			<content:encoded><![CDATA[<p><strong>H5N1 Avian Influenza History And Disease Characteristics</strong><br />
As a rule, influenza viruses seem to be very specific in terms of which species is affected by which virus strain. This means that a virus that is infecting birds, pigs, horses or even seals, will generally continue to only infect those specific species. Rarely will a virus “leak “into a different species. In the last fifty years cases of human contagion due to an avian influenza have been recorded in only ten instances. There are literally hundreds of varieties of avian influenza virus and yet just four have been confirmed as having caused any human infection: H5N1, H7N3, H7N7, and H9N2. When these viruses infected humans the result was only mild sickness and  light symptoms – exceedingly slight harsh illness and only one is the exception, the extremely transmittable H5N1 bird virus.</p>
<p>There are many flu viruses in the avian populations but the H5N1 infection is the most worrisome for health service officials for a couple reasons. </p>
<p>One, H5N1 infection has been responsible for the highest number of recorded cases of extremely virulent illness as well as the highest mortality rate. On three occasions it has jumped species to infect humans most recently in 2004 and our current trouble, but also in Hong Kong in 1997 when there were  18 infections and one third of them fatalities and also Hong Kong in 2003 with 2 cases and one death.</p>
<p>Two, and even more disconcerting is that the current H5N1 virus runs the risk of mutating, if enough chances are presented to it, into an infection of pandemic proportions. Thus far the H5N1 virus has displayed all the rudimentary qualities it needs to initiate a pandemic except one critical component, the capacity to be effectually transmitted from human to human. While currently the H1N1 virus is at the critical pandemic level, the potential for a pandemic to develop from a mutated human version of H5N1 virus must not be ignored.</p>
<p> The H5N1 virus can suddenly begin infecting people in two ways. The first is in an exchange process between viruses. The genetic matter is passed between a human and bird flu virus while there is a mutual infection of the two viruses with a person or a pig. This trade of material or shuffling process could mean the mutated result is a very dangerous and highly infectious pandemic virus and would be introduced into society by a rash of human cases and a rapid spread.</p>
<p>Another method would be slower but no less perilous, adaptive mutation is caused by the virus attaching to human cells in a steady manner through successive human infections and the virus becomes more capricious and pernicious as it gathers momentum forming small groups of human illness where there is confirmation of person to person contact. This second version of events would at least, if discovered early enough, give authorities some valuable time to respond.</p>
<p>In the Hong Kong H5N1 influenza spate of 1997, there were eighteen cases of illness which happened to take place when there was an outbreak of a far more severe and contagious bird flu by a virtually matching strain of the virus occurring on poultry farms and in public poultry markets. Intense follow up  studies with familial and personal contacts of the patients, health care personnel, and those who culled flocks of birds determined there was little confirmation, in not any at all to confirm the spread between humans. In three days time, the culling of all poultry in Hong Kong ensured there was no further human infections. This at the expense of a million and a half birds that world medical officials credit with preventing a pandemic of avian influenza.</p>
<p>Everything up until now points to humans making contact with infected or dead birds as the primary source of illness in humans from H5N1 virus. People at risk are those who butcher, pluck feathers, initiate the bird kill process and those who process poultry meat for consumption when handling infected bird carcasses. Some individuals came into contact with chicken feces specifically using a poultry free range as a playground for kids and subsequently became ill. Experts also believe that swimming in water that contained dead bird cadavers or where infected birds could have contaminated with their droppings is potentially a further cause of some infections.</p>
<p>Not all cases of initial virus exposure could be indentified making authorities consider the possibility that some undiscovered infectivity factor with the virus may be the cause of certain cases. Some thoughts about what this cause may be area possible connection with feral birds such as pigeons or perhaps employing bird droppings as a form of fertilizer. For the time being H5N1 avian influenza is primarily a bird illness. The obstacle of single species strains of flu is noteworthy since the virus does not transfer from birds to humans without difficulty.</p>
<p>Notwithstanding the fact that there have been millions upon millions of diseased poultry in huge areas since the year 2003 there have only been less than a couple hundred cases of clinically diagnosed human H5N1 infection. There must be a reason, as yet not understood, why many of these infections occurred out in the country or semi rural locations where families and farmers maintain smaller stocks of poultry. It is also an anomaly that there are fewer infections in those groups that would ordinarily be considered at greater risk such as industrial poultry personnel, live poultry market vendors, those who cull flocks, veterinarians, health care workers who aid the patients that are ill, many not having the proper safety gear to do so without leaving them vulnerable.</p>
<p>There is also a lack of data or understanding of why kids who were in good health and medically fit young adults seemed to get ill. Health officials need to quickly discover logical reasons for this type of exposure. Are there certain behaviors involved? Perhaps there are immunity or genetic circumstances that seem to leave these groups vulnerable to infection?</p>
<p><strong>Evaluating Potential infections in People</strong></p>
<p>Examining many of the verified human infected with H5N1 virus, those in Asian nations and in Turkey, showed that direct contact with diseased avian species as presumably the primary reason for exposure. When reviewing likely infections, medical personnel should be inclined to look at those people displaying signs of influenza symptoms such as respiratory illness, hyperthermia etc. and those persons with a close proximity to birds. Particular attention should be paid to those presenting with these symptoms who reside in locations of verified outbreaks of the contagious H5N1 bird flu are active. If those presenting symptoms are from an environment where avian fecal matter  may have caused contamination then than perhaps this would be a secondary consideration for exposure. </p>
<p>To this point, human infections of H5N1 virus are not all the responsibility of contact with diseased carcasses or tame bird stock that look like they are ill. In 2005 reports showed that domicile ducks could emit large amounts of high contagion virus but display none of the illness symptoms. There was no threat to people who ate poultry from these countries provided they cooked their poultry well and those people did not take part in prepping the food. </p>
<p>Since there is not a sign of any person to person spread of this virus anywhere, there is no discernable hazard for anyone travelling to these countries where outbreaks occur provided obvious precautions are taken such as staying away from open air poultry markets, farms or any other location where diseased bird contact is imminent or has occurred in the past.</p>
<p><strong>How Clinical Symptoms Present</strong></p>
<p>When a patient with H5N1 influenza becomes ill the infection is usually quite aggressive during its path, with patients displaying a fast decline with an elevated mortality. As with most new diseases, H5N1 influenza has a long learning curve for health officials. Health services data compiled in 1997 along with the latest epidemic are only now starting to illustrate the clinical characteristics of the infection yet there is so much left to study. Making matters worse is the fact that the virus has a habit of mutating quickly meaning its unpredictable nature makes disease mapping that much more frustrating for researchers.</p>
<p>The infection development phase for H5N1 avian flu is probably longer than the more common seasonal influenza which stand around two or three days. Any current information regarding disease incubation shows a range of two days to eight and quite probable extending to a length of seventeen days. But the Likelihood of numerous exposures to the H5N1 virus means accurately calculating a disease development period quite difficult. The WHO is currently saying clinicians should use a seven day gestation period in order to conduct examinations at ground zero for illness and when observing patient acquaintances.</p>
<p>The illness presents itself through elevated temperature, higher than 38° Celsius with influenza type indicators. Vomiting and diarrhea, stomach pain, chest pain and gum and nosebleeds have been cited as pre symptomatic signs with certain patients. Watery diarrhea with no blood seems more common in H5N1 than in the season variety of flu. The range of illness symptoms may be wider still. Verified patient illnesses have not all included respiratory problems.</p>
<p>Several Vietnamese persons infected the diagnosis was severe encephalitis: neither of these people showed any respiratory distress when they presented. Another infection in Thailand had the patient presenting with hyperthermia and diarrhea but no lung/breathing distress. In all three of these infected patients they had been in direct contact with diseased  poultry.</p>
<p>A characteristic observed in a number of illnesses was the development of indicators in the lower respiratory tract in the beginning stages of the illness. Many patients display these lower respiratory symptoms when initially looking for treatment. Based on current knowledge, breathing irregularities begin to manifest about day five of the onset of illness. Respiratory trouble, hoarseness in the voice, and a discernable crackly noise while inhaling are most likely observed. Phlegm production is erratic and occasionally tainted with blood. Lately there have been bloody respiratory secretions seen in Turkey. Nearly all patients wind up with pneumonia.</p>
<p>Throughout the Hong Kong influenza illness spurt, the severely sick people showed primary viral pneumonia that antibiotics couldn’t help. Inadequate information about patients in the current outbreak show the signs of primary viral pneumonia in H5N1 that usually fail to show signs of bacterial supra-infection when determining diagnosis. Turkey medical officials have documented pneumonia as a consistent characteristic in more harsh cases, and the same as other patients, these people did not respond to being treated with antibiotics.</p>
<p>Those patients with H5N1 Influenza suffer a quick decline in their illness. There was a six day time period from the beginning of the flu to respiratory distress in Thai patients with an overall spectrum of four to thirteen days. Severe Turkish H5N1 illnesses the respiratory decline was three to five day after initial symptoms appeared according to medical experts. Something else which appears all too common is the irregular function of multiple organs. General laboratory anomalies, consisted of leukopenia (chiefly lymphopenia), mild-to-moderate thrombocytopenia, prominent aminotransferases, and with several occasions of disseminated intravascular coagulation.</p>
<p>There is some confirmation that particular antiviral medications, especially Oseltamivir or generic Tamiflu as it is known commercially, as they decrease the ability of the virus to reproduce thus improving the odds of survivability. They must be taken inside a forty eight hour window from the start of symptoms to be effectual. Data collected from the Turkish outbreak suggests that the majority of those with the virus were diagnosed and treated well into their course with the illness. It is because of this information that the use of Oseltamivir as a treatment is somewhat incomplete. </p>
<p>Oseltamivir or Tamiflu and other antiviral medications where produced as forms of treatment and as prophylaxis methods for seasonal variations of influenza, known to be a less severe version of flu as well as having a longer virus reproduction process in the body. The options for treatment courses and dosage quantities are still in a state of fluidity for oseltamivir – tamiflu therapeutic treatment of H5N1 influenza as it is with child illness of the virus. The WHO is continually monitoring and reviewing these antiviral practices as they require vital revision.</p>
<p>When a case of H5N1 influenza is suspected, generic tamiflu needs to be prescribed and taken as quickly as possible, preferably within forty eight hours from becoming symptomatic in order to optimize the value of the medication. Given the virulence of the current strain and the length of time of replication process, mortality rate etc. it would behoove the primary physician to begin treatment with generic Tamiflu also in those patients who are well into the illnesses course.</p>
<p>The existing suggested dosages for generic tamiflu for influenza virus treatments can be located on the Manufacturer – Roche’s website under product information. Currently the optional dose for generic tamiflu for influenza therapy is 150 mgs daily for children thirteen years and over and also adults, administered twice daily at 75 mg each for a course of five days minimum. There is no record of Tamiflu treatment for kids under one year old. The WHO health experts are looking into issuing treatment dosages and recommendations for children under the age of one year.</p>
<p>Since H5N1 viral reproduction periods could be extended, clinical personnel should reflect on increasing the tamiflu course treatment from five days up to seven or ten days in patients who are not responding to average treatment courses. When a patient displays severe H5N1 infection, they may want to raise the suggested daily dosage or length of treatment time. Clinicians also need to remember that Tamiflu dosages higher than 300 mg per day can be responsible for an increase in adverse effects . These same clinicians may want to consider administering serial clinical samples for future examination so viral loads can be monitored, an assessment can be made on medication susceptibility and levels of tamiflu can be reviewed. But, these samples should only be ingested where suitable procedures for infection control are available.</p>
<p>When a patient with H5N1 is suffering from a severe form of the illness and hampered by gastrointestinal symptoms, the absorption of Oseltamivir – Tamiflu could be hindered. Clinicians need to be cognizant of this prospect when treating patients such as these. </p>

			<content:encoded><![CDATA[<p><strong>H5N1 Influenza May Appear Off The Radar But Vigilance Is Vital</strong><br />
With all eyes seemingly on the H1N1 influenza  strain health officials the world over are still monitoring the H5N1 bird flu strain since it has the potential to be far more destructive if it infects humans via humans. There is concern that a global recession may be threatening surveillance and prevention measures that are keeping the fatal bird flu virus at bay.</p>
<p>The recorded cases of H5N1 have been dropping in previous years but the H5N1 strain is known to vary in intensity year to year, though the drop is an indicator that efforts to manage the virus have been somewhat successful in domestic poultry birds. There has been better observation of the disease globally and China has instigated a huge poultry inoculation endeavor but China has experienced a cluster of illness from bird flu that felled eight people in one month. Six of those cases were in areas with no reports of outbreaks in their poultry stocks.</p>
<p>Influenza H5N1 is still difficult for humans to contract, it has still claimed two hundred fifty four victims around the world since 2003. Health scientists have been sounding the alarm for a while now that if H5N1 wasn’t under control in the avian population it could well mutate into a modified strain that would infect humans and cause the spread to activate the strain into a pandemic. </p>
<p>The peril is that after years of controlling this H5N1 strain and keeping it from becoming a more serious threat to humans there could be slippage in vigilance due to economic stress and general flu fatigue. After years of pandemic preparedness operations and a recession, would there be a call for financial curbs on funding? A number of less resourceful nations could be the impetus for this to happen.</p>
<p>The World Health Organization still thinks a flu pandemic from H5N1 virus is only a matter of time, there is no IF in the equation. The international community must keep a vigilant eye not only for modification of the H5N1 virus but also for other influenza strains in addition to what has already been identified. We are already a world under threat from a pandemic of H1N1 influenza and if these two viruses were to somehow mutate from mutual contact the result could be catastrophic.</p>
<p><strong>Bird Flu Symptoms And Treatment Protocols</strong></p>
<p>People who contract the H5N1 illness will present with hyperthermia or fever, sore throat, cough, severe respiratory distress and viral pneumonia. People of all ages can be infected and can be in various situations with their health. Today there are tests that can be performed quickly in order to diagnose a particular influenza strain. Antiviral medications like Generic Tamiflu or Oseltamivir are considered effective for treating and preventing the influenza A strains of the virus and this is good since when a new strain of flu develops it can take a good number of months to produce a viable vaccine.</p>
<p>The WHO is recording and posting regular updates concerning any new human infections of H5N1 Bird flu. They must gather information as to how the person was exposed to the virus whether by wild or domestic birds and which species of bird they made contact with. It’s critical to inform the public not to keep wild birds with domestic flocks, not to allow free ranging poultry, to keep the public away from wild birds, or keep in captivity any wild birds’ period and this must be done to aid in preventing a global pandemic. The public must continually wash their hands after coming in contact with poultry stocks or subsequent to handling chicken meat, cooking poultry well and keep domestic bird species separate from each other.</p>

			<content:encoded><![CDATA[<p><strong>Nations Face Quandary Over Avian H5N1 Virus</strong><br />
Because of the many questions unanswered regarding the current avian influenza and the risk it poses, nations are faced with a predicament: How can these governments commit their limited community health services financial resources to a latent yet possibly disastrous occurrence. Research clinicians testing a chicken’s blood at a renowned contagion control hospital in China warn of a highly contagious bird flu virus with the wherewithal to claim millions of lives in a global pandemic.</p>
<p>The risk would be calculated but how do you respond when there is no way to forecast when it will get severe and yet the cost of doing nothing could be ominous. It is an impossibility to know in advance when a bird flu pandemic will happen and so forecasting a crisis is difficult and the possibilities are vast. What is certain is that the next great pandemic is nearing its due date if not having surpassed it. </p>
<p>The twentieth century bore witness to three deadly pandemics. The Spanish influenza in 1918 -1919 in which some estimates claim nearly fifty million people perished. The Asian influenza of 1957 -1958 with approximately one million fatalities and the 1968 – 1969 Hong Kong influenza took anywhere from one million to four million lives. Estimates vary widely as a testament to the lack of record keeping and resources during a major worldwide health crisis. </p>
<p>All three of these outbreaks are believed to have had their origins in avian species. There are fifteen known bird flu virus sub variations and H5N1 is specifically anxiety producing. This strain of avian flu has slammed domestic bird sectors in eight nations, of these three of them, Cambodia, Thailand and Vietnam, have reportedly had altogether seventy nine human infections and more than fifty percent of these illnesses were deadly. </p>
<p>Never has there been such destructive fallout to so many nations by the H5N1 bird influenza virus at once causing anxiety to populations and economies to suffer so greatly in both farms and residences as well as industrialized poultry producers. The H5N1 Bird flu strain has displayed two frightening characteristics thus far, the ability to spread infection quickly and to cause harsh disease in humans. What it has not yet shown is the capability to spread human to human. If and when this third indicator appears it would be considered the beginning of a pandemic and would certainly prompt an international reaction from The World Health Organization and the initiation of emergency preparedness plans for an influenza pandemic.</p>
<p>The worry right now is that this H5N1 bird flu virus could mutate, it has a history of doing just that, developing the means to spread more easily from person to person contact. Experts wonder if this mutation or change could occur from adjusting to the infected masses or via an inherent modification with a known human influenza virus. Currently the infection is spread through direct human exposure with contagious domestic poultry.</p>
<p>The WHO has stated that there is no confirmed link of any continued person to person diffusion instead there were limited infection sequences that remain quite typical in bird flu virus not yet tailored to people. It is understood by authorities that each specific cluster of infected persons could be an indicator of an oncoming pandemic, meaning each case needs to be examined promptly.</p>
<p>Expert clinicians concur the unparalleled scope and transmission of H5N1 bird flu has increased the chances of a serious influenza pandemic reoccurring, their human mortality approximations are anywhere from two million to fifty million globally. Because of international travel being so common and the massive amount of trade between countries there is little that can be done to inhibit the spread of the virus worldwide.</p>
<p>When SARS [severe acute respiratory syndrome] was a problem a few years ago, infected persons were able to be identified and quarantine measures taken at airports. H5N1 Infected persons during a pandemic are going to be able to infect anyone they come in contact with before symptoms even start to present. This is a real concern for the medical and health services since infected travelers won’t be caught at the airports this time.</p>
<p>The WHO is asking all of its member nations to urgently review and revise their influenza pandemic emergency response plans. It is mainly industrialized, more affluent nations that have done these revisions while many others are scrambling to do so. These preparedness plans are based on suggestions made by the WHO to utilize a phased reaction in order to decrease the feared force of any influenza pandemic. </p>
<p>The plan is to produce a vaccine quickly and warehouse antiviral medications such as generic tamiflu or Oseltamivir, which has displayed an effectual response to the H5N1 bird flu virus. Generic Tamiflu will probably be as effective against any upcoming flu strains in the future as well. The WHO has also recommended thirty other pandemic guidelines not related to medical intercession that should prove valuable if we are facing a pandemic.</p>
<p>If we make the assumption that the H5N1 has its roots in the Far East Asian nations we must also assume that we will not be able to stop it from reaching the industrialized western nations of North America and Europe. When it lands here it will hit with a ferocity racking up illnesses and causing havoc with our daily lives. Preplanning for this event horizon will go a long way to decreasing the effect overall on the national communities  affected.  </p>
<p>The United Kingdom has decided to acquire nearly fifteen million therapeutic courses of anti viral medication Oseltamivir or Generic Tamiflu. This means treatment can be given to one in four Britons who could potentially be infected, this number estimated by the WHO for antiviral stocks on hand. Great Britain is only one of a number of countries that are stockpiling Tamiflu and other antiviral medications. They are also taking part in the research to quickly ramp up production of a vaccine against any future H5N1 pandemic flu outbreak.</p>
<p>Current influenza vaccines won’t give any defense against a future pandemic flu virus. But knowing that a potential mutation will initiate from H5N1 and have little difference genetically, The WHO is urging its members that preventative warehousing of current vaccine may be an option of some protection for wealthier countries to consider. At least it would be available immediately and it may offer a certain amount of help from the human exposed pandemic virus. There is the hope that  this could also bring about investment from companies to begin pandemic vaccine development. Vaccine has an expiry date of a couple years so it could in the end just be thrown away but it would be considered cheap insurance in the event of a full blown pandemic health crisis.</p>
<p>Countries like China, France, Canada, Japan, the UK and the United States have made arrangements with manufacturers to produce a sample H5N1 vaccine, but if any new flu strain is drastically modified from the H5N1 virus the vaccine will be deemed ineffective. This on the back of a report from the WHO stating that a vaccine offering protection against the H5N1 as it is now could be nearly as effective against a new variation. Error on the side of caution according to the richer nations.</p>
<p>For the first time many countries are affected outright by the disease and the economic losses alone are overwhelming for farmers, industrial poultry producers and common households in these countries.</p>
<p>Currently the vaccine production is taking place in Australia, North America, Europe and Japan but during a pandemic the need will stretch around the world. There are concerns that less affluent countries seem to get hit the hardest by the influenza pandemic because their people tend to be less fit and undernourished. Poor countries have fewer health service staff and weaker health organizations overall that can’t stand up to the load of a pandemic virus and are lacking an emergency preparedness plan of any significance.</p>
<p>Because of a lack of resources most emergent nations are concentrating on surveillance of the H5N1 disease rather than warehousing antiviral tamiflu and vaccine production. If a pandemic hits these areas they will be extremely susceptible to illness in overwhelming numbers and not have the medicinal resources to anything about it.</p>
<p>The danger faced by humans from H5N1 flu has been second guessed lately. Medical personnel initially approximated the mortality figures at about ninety percent but adjusted that number as additional cases became obvious so the number dropped down to sixty seven percent along with newer confirmation of a lack of symptoms shown in many people so there may well be more cases that go unnoticed making an accurate death toll difficult to predict and possibly much lower than originally considered. It should be mentioned that a lower death tally doesn’t necessarily mean a lesser menace to humans from the H5N1 virus.</p>
<p>With H5N1 it was always suspected that the illness cases to death ratio seemed strangely elevated and the range of illness more general than only severe cases that were being recorded. Still, with lower fatality numbers based on more cases of illness, easier spreading of the flu virus means more people will get infected and hence, more individuals will become fatally ill.</p>
<p>The WHO is still quite certain that a pandemic of H5N1 virus will hit us globally. Regardless of all the unanswered questions surrounding the bird flu virus and its shock to society, preplanning for a pandemic will have a positive effect on the outcome. Lives will be saved, some will be lost, and the economy will still take a beating along with societal structure in general but emergency response organization will be improved and that is at least something positive. Better to be prepared as much as possible regardless of a nations internal capabilities.</p>

			<content:encoded><![CDATA[<p><strong>Don’t Panic &#8211; Start Planning For Avian Influenza Pandemic</strong><br />
The H5N1 Avian Influenza, referred to as simply “the bird flu”, is a contagion that is spawned by bird viruses that happen naturally in birds. It is fairly normal for birds to carry a virus but this specific H5N1 virus in exceptionally infectious. The good news is they have mainly caused illness in bird populations such as ducks, chickens and turkeys. The birds convey the infection through their body fluids and human raised poultry when contact is made. The infected avian population then gets ill in a mild form or severely and fatally.</p>
<p><strong>What is the risk of Avian Influenza to human health?</strong></p>
<p>Anxiety over an H5N1 influenza pandemic has become significant in many countries. Medical experts around the world state that in the event of a bird flu virus mutation which is then infectious person to person, the medical outcome in terms of morbidity and mortality on humankind would be horrendous.</p>
<p>Until now human infections have been caused by direct transmission from bird to human or from diseased surfaces from bird excrement. People need to realize that it is unusual for human to human transmission. The odds of infection in this manner remain quite low and for those people who have become infected through avian contact the result has been a severe form of influenza and fifty percent mortality.</p>
<p> Apprehension is high in populations because of the ability for influenza viruses to change into a new strain with the potential to infect people around the world. This would be the case if the H5N1 virus began the steady mutation process and began claiming victims due to human to human transmission.</p>
<p>Up until now there is no sign of any form of person to person infectious capability with the H5N1 bird flu virus. Also there has been no confirmation by any firm means that a new strain of avian influenza is about to menace the world’s population. That said, agencies such as the World Health Organization or WHO are on guard for any unusual events with this avian virus, so we try and remain calm about it all.</p>
<p><strong>Is There Anything We Can Do To Stop Bird Flu?</strong></p>
<p>Currently there is really only a vaccine for avian flu that is so new it hasn’t been tested by difficult illness scenarios and is still really in production/trial phases. What people need to remember is that washing hands thoroughly and frequently is still probably the best preventative solution of all. If you have been exposed to the bird flu or contact has been made with an infected individual, you should wash your hands before doing anything. Keep your hands away from your mouth nose and eyes. When you wash your hands count to twenty to do the job thoroughly.</p>
<p>Remember your common sense precautions including hand washing, sneezing or coughing into a tissue or into the crook of your arm works too. Keep up with your seasonal flu injections. The annual vaccine for seasonal flu won’t help you with the bird flu but it will inoculate you against the seasonal variety. If a person was suffering with the seasonal flu and made contact with the H5N1 virus the result could be a viral perfect storm allowing the mix to mutate the avian strain into a different and perhaps more virulent and infectious. </p>
<p><strong>There are some measures that can be taken to aid in the prevention of a severe global pandemic of avian flu which comprise:</strong></p>
<p>Depending on personal circumstances some individuals are stockpiling N-95 face masks and or throwaway breathing apparatuses, some type of eyesight defense, hand protection, protective clothing, and hand sanitizer in addition to other practical safety gear.</p>
<p>Plan to teach anyone who will require it, the proper use of this equipment, disposal of waste and the process for disinfection of personnel and equipment. In the event of a pandemic the resources you need may not be available and it could be too late to prepare otherwise.</p>
<p>Be sure that all medical supplies are usable and there are sufficient stores of essentials. The medical kits should contain basic first aid materials and any prescription medications needed to get by. A supply of OTC medicines for stomach relief, pain killers, colds, cough and allergies. This kind of kit is useful in a number of emergency scenarios, not just a pandemic situation. </p>
<p>Be sure everyone at home and work are aware of sanitary hygiene like proper hand washing with soap &#038; water particularly before and after meal preparation and after using the bathroom. Regular hand cleaning with alcohol based [minimum 60% alc.] hand sanitizer and proper etiquette for controlling coughs and sneezing when around others to avoid spreading germs.</p>
<p>Again, all people should have a supply of their prescription and non prescription  medications on hand as well some energy drinks like Gatorade and other fluids containing vitamins etc in case of a long stay indoors.<br />
Families should start stocking up on water and food in advance of a pandemic. Having enough essentials on hand during an outbreak in the local area that can sustain a family for 2 weeks is advisable. It must be reiterated that in case of a pandemic, it may not be as easy as just driving to your grocery store if employees are ill or stock isn’t being transported while the threat passes. Stores may close so be prepared.</p>
<p><strong>Avian Flu: Potential Crisis</strong></p>
<p>As of now the H5N1 avian influenza virus has been concentrated in Asia, the Middle East and areas of Europe. Everyone else is closely observing the bird flu virus trying to ensure it doesn’t enter anymore countries. The avian flu is fairly common in feral birds but can wipeout populations of domestic poultry/birds very rapidly. The worry is that humans are not equipped with a natural resistance to bird flu virus, so if it mutates and becomes aggressive in humans there is no defense, only medical intercession. Fortunately the strain has not yet mutated, unfortunately this also means that a vaccine cannot be produced to control a new mutation. Currently the only way to repel thee H5N1 virus is through stringent prevention measures that are followed by non infected populations.</p>
<p><strong>Avian Influenza Pandemic Personal Preparedness Plan</strong></p>
<p>In a pandemic there will most certainly be things you can do to limit exposure and keep your family safe. Social distancing is critical to avoid infection, even when there is only limited illness locally, in a pandemic this can change extremely quickly. Start planning now for future potential exposure to the virus. That means when the local outbreak is in full mode you want to remain isolated from everyone outside of your immediate family. You should leave your residence for essential shopping only such as fuel, water, drugs and food. Hopefully you have stocked a supply in advance but there may be a need to venture out so take some precautions.</p>
<p>With this in mind you should only be traveling to the grocery store, gas station, discount store, pharmacy, or convenience store. This is not an ideal time to be strolling through the mall or window shopping.</p>
<p>Go on these shopping expeditions during the slowest possible times so your exposure will be limited to as few people as possible. Now would be a good time to explore which stores are open 24 hours. Find out the hours of these stores and which are open late in the evening or early in the mornings. Find out the time that you will likely be the only patron other than a couple employees.</p>
<p>Be sure to have your vehicle/s topped up with gas since  fuel may be out of stock due to a run at the pumps or lack of fuel delivery. Do not drive far for supplies given potential fuel supplies. Make substitutions in your planning if necessary – if a grocery store is open 24 hours at 4 mile distance it would be worth going at 5 am if variables above are right rather than going fifteen miles for the same thing – that would waste gas.<br />
Walking is fine if you do so during the day though there will be more people out, your safety is more important. Some individuals tend to get reckless with their behavior in a time of crisis. Local law enforcement may not be as prevalent during a bird flu pandemic so walk in daylight if necessary and drive at night for your protection.</p>
<p><strong>What supplies you should buy:</strong></p>
<p>Bottled water &#8211; Canned vegetables &#8211; Canned fruit – Sauerkraut [promotes the development of good bacteria in your body which aids in repelling H5N1 [in Asia you can use Kim Chi] – manual can openers –garlic – onions – canned or cooked meat – fresh meat if you have the means to continue cooking it.<br />
Fresh vegetables – fresh fruit – horse radish – ginger root – dried meat – cheese preferably low in fat – eggs – fresh milk – powder and canned milk – canned fish.</p>
<p>You need superior vitamins and health supplements, specifically vitamin C – selenium – zinc – Omega 3 – lysine – beta glucan – vitamin E – beta carotene – vitamin B complex – green foods that have chlorophyll – ginseng – resveratrol – magnesium – DHEA – quercetin – bioflavonoids – yogurt.</p>
<p>Soap [extra water for washing] – alcohol sanitizer wipes – Antiseptic hand lotion – propane – kerosene – First aid kit with tea tree oil and nu-skin – hot and cold packs – vaporizer – dental cleaning supplies – toilet paper and diapers – various cleaning soaps – reading materials – jigsaw puzzles and deck of cards.</p>
<p><strong>What won’t be necessary:</strong></p>
<p>Useless herbs and supplements that do nothing to augment your immune system – candy bars and snack foods – sugar and sweets – bread – rice – spaghetti and noodles/ pastas – cigarettes – alcohol – fruit juices – soda pop &#8211; Decrease your odds of becoming infected by the avian influenza H5N1 virus by boosting your immune system and to survive in the event that you are infected by it. Avoid anything that raises your chance of becoming infected by avian flu and avoid everything possible that can deteriorate personal immunity. A pandemic  is something you have no control over but you can protect yourself and your family. It is not the time to be personally indulgent nor is it a time to be self conscious about protecting you and yours so take the required actions to beat the odds.</p>

			<content:encoded><![CDATA[<p><strong>Emergency Measures for H5N1 Influenza Pandemic</strong><br />
The ongoing pandemic of the extremely contagious H5N1 version of the avian influenza virus has a fatality rate of about fifty eight percent. It is presenting itself as quite relentless in much of southeast Asia, specifically in Thailand and Vietnam. It does seem to be an inefficient virus there has been some confirmation of person to person contact in the transmission of the virus. If unchecked it could become a potentially disastrous pandemic because of mutating viral antigens meaning a very contagious strain of H5N1 could develop. The last century saw several deadly pandemics in 1918 – 1919, 1957 – 1958, and 1968 -1969 which were virulent enough to claim an estimated thirty million, four million and seven hundred fifty thousand fatalities in that order.</p>
<p>Any chance for a vaccine to combat the H5N1 influenza will probably take a while yet to produce. Should the major pharmaceutical companies start producing immediately after an epidemic occurs, there won’t be enough of the vaccine to offer any kind of adequate provision for the nations that are in dire need – meaning the Asian countries. This means that for the foreseeable future antiviral medications such as oseltamivir –generic tamiflu and zanamivir – relenza and perhaps other older antivirals such as amantadine and rimantadine are going to be the first line of defense.</p>
<p>Drugs such as generic tamiflu and amantadine are referred to as neuraminidase inhibitors which both decrease and shorten the severity of flu symptoms and they can provide prevention measures from influenza as subsequent contact and seasonal prophylaxis medications. Influenza preparedness strategies recommended by the World Health Organization, WHO, and many governments globally as a rule support detection, isolation, primary responder protection, and beginning antiviral treatment therapy for those with the illness and those in contact with them. Most national governments have already begun warehousing at exorbitant costs, huge amounts of generic tamiflu [Oseltamivir] in preparation for a potential epic rash of illness. </p>
<p>in any case, the effectiveness of the neuraminidase inhibitors, even when taken as a prophylaxis in healthy people taken within the forty eight hour window from the beginning of flu symptoms is only small. The utilization of tamiflu in five of ten cases documented in Vietnam did not display any clear medical effectiveness and there was an eighty percent fatality rate found in this effort. Neither tamiflu – oseltamivir nor relenza – zanamivir, were directly evaluated in the restricted study.</p>
<p>Both antiviral medications have related pharmacological properties and both offer comparable effectiveness; zanamivir- relenza appeared to have fewer side effects to manage and a better resistance report. This resistance report would carry much weight in the event of a pandemic. The zanamivir is not being stockpiled in anywhere near the amounts as tamiflu is and this could be because of the potential challenges of administering an inhalant medication for children and intellectually impaired persons. Zanamivir does have some original and practical methods for use in children.</p>
<p>The incidence of bronchial problems and decreased lung utility is not very common, and those suffering with asthmatic conditions and chronic obstructive pulmonary disease or [COPD] are able to abide by the inhalation of the zanamivir – relenza,  along with the placebo. Zanamivir has options for dry inhalant devices which are popular among these same patients even in times of problematic situations with their illnesses.</p>
<p>With this in mind, nation governments need to contemplate warehousing zanamivir as an antiviral option along with generic tamiflu as part of their emergency preparedness planning. The antivirals must be dispensed to ill patients and those who have been exposed to them within forty eight hours of becoming symptomatic. The logical position for health officials to take is allowing community health care services and drug store pharmacists to be responsible for getting the antivirals medications into the hands of those who need them in a timely manner rather than counting on potentially overstretched hospital based health providers to do the job.</p>
<p>All nations and their health services sector should include H5N1 study trials in their preparedness planning testing a dual role for tamiflu and zanamivir with prospective new medications and not; specifically testing SIRNA’s and interferon. These are in experimental phases now and hold promise as antivirals. More important is that these studies when conducted in the outset of a pandemic offer valuable data for late stage virus control and patient care. Vaccine producers are located mainly in wealthier industrialized nations and so delays getting the bird flu vaccine into the underprivileged Asian countries that need it. The wise decision would be to initiate some production of neuraminidase inhibitors and vaccine in these areas to rectify these shortages. Questions arise about drug patents during a pandemic that could lead to global crisis. </p>
<p>From a virus control perspective having available tamiflu and zanamivir antivirals stockpiled and or produced in these outbreak countries would aid in controlling the anticipated spread of the illness, nipping it in the bud so to speak. Developers such as Roche for oseltamivir [generic tamiflu] are already licensing out to many overseas countries. India has pharmaceutical companies prepared to begin producing generic tamiflu but cannot obtain government approval to do so. Restrictions and red tape need to be removed in order to take the fight to the virus with as much clinical punch as possible.</p>
<p>Medical study modeling has displayed to researchers that H5N1 influenza is more contagious than severe acute respiratory syndrome [SARS virus] and the preparations and management model for controlling SARS may not be sufficient for a pandemic of influenza, particularly H5N1. If this isn’t looked at and changes aren’t made to these plans the community health services in infected nations will become strained to the maximum in short order. SARS showed that when hospital personnel are under equipped in staff and resources they become discouraged and personnel begin to abandon their posts. Especially when these first responders begin to see their co workers become infected by clinic borne H5N1 contagion and they aren’t treated in an ICU setting. Health care officials at all levels of government must see that they protect their health care providers and show they are being conscientious. These health care professionals on the front line will also be depended on for their skills to handle the repercussions of a pandemic so their continued health should be paramount in the planning stages of a pandemic.</p>

			<content:encoded><![CDATA[<p><strong>Bird Flu Virus At Ground Zero – Now What</strong><br />
What would happen if the H5N1 bird flu virus erupted in your community? The following is an account of the reaction to the H5N1 virus when an outbreak was first discovered on an island in Germany, a tourist destination called Rugen. </p>
<p>In January of 2006 there was an increase in the number of dead bird remains located in East Germany that the Parks Commission believed was simply an average natural occurrence due to a longer and tougher winter than normal. By mid February on the 14th a traveler reported discovering four dead swans on the eastern side of Rugen. Rapid testing of the bird corpses pointed to H5N1 as a potential threat and avian influenza was eventually confirmed.</p>
<p>The next day there were more bird corpses found and it was mandatory that all domesticated birds be penned up. The Government executives held an emergency assembly to discuss the situation in more depth.  On the 16th of February it became publically confirmed that the cause of these bird deaths was H5N1 and the avian fatalities kept coming. The 17th of February there was a call that all birds nationwide must be kept in pens or stalls or inside a form of defensive cover. This included all chickens, ducks, geese and turkeys to be what amounted to quarantine conditions in their locations. Discussions are continuing between officials for improvements to their preparedness plan and revisions are made if needed.</p>
<p>The following day the entire island of Rugen is placed on alert. A secure perimeter of three kilometers or two miles is put in position around the  expired birds and a further secure zone for surveillance is in effect at the ten kilometer perimeter. The sale of all birds is halted and any automobiles, passenger buses and  trucks are disinfected. Birds inside the 3 kilometer sector are disinfected as well. The local populace is told to call police, fire officials or veterinarian clinics if they find any deceased animals at all. They are warned against handling them and to only make a report.</p>
<p>On the 19th of the same month dead birds are discovered  on the principal German landmass. Things are becoming serious quite rapidly. On the 20th, the entire eastern coast region of the country is placed on alert and each individual county in the nation was now preparing for the calamity approaching. </p>
<p>While this was all occurring, firemen, the military, experts and volunteers were in Rugen. Certain ones were outfitted with masks, others in full body protective outfits in order to aid in disinfecting operations and still some were just there to observe and account for the birds answering queries from citizens. There was an influx of 1280 masks, 1550 throw away protection suits along with 150  non disposable outfits, 1200 pairs of protective goggles, 1150 pairs of boots, 1700 pairs of gloves and one thousand liters of disinfectant. Outside the protective perimeter there were 11780 more face masks, 11,560 throw away suits, 10,072 protective eyeglasses, 9140 sets of boots and 5000 more liters of disinfectant agent as a backup resource. There were also nearly 40 unique epidemic beds and 370 individuals who were ready to assist or already pitching in.</p>
<p>If there is anything to be learned from this story its do not panic. When a Breakout occurs of H5N1 flu virus a concerted effort to contain the disease is called for and combined resources of a community can assist greatly to quell the threat. Diagnostic testing is becoming much better in and quicker when testing animal corpses and the response to the situation is in a state of fluidity. The Public has a responsibility to keep a keen eye open for dead birds and notify authorities when they are found. </p>
<p>A significant observation is that the German public showed no signs of panic, just a sense of getting the job done and a positive reaction to the situation. A German Government official stated that he would have preferred an even quicker reaction to the crisis, it is obvious the circumstances were dealt with in a well managed way. It serves as an example to other countries when they are confronted with H5N1 influenza at ground zero.</p>

			<content:encoded><![CDATA[<p><strong>Mouse Studies Pits H5N1 Bird Flu Virus Up Against Tamiflu Antiviral Drug</strong><br />
Scientists who conducted an experiment using mice confirm that the antiviral medication generic tamiflu currently being used to combat and control seasonal influenza is also capable of thwarting the deadly H5N1 avian influenza virus. Bird flu, as it is known, has spread from the avian population to humans causing copious fatalities amongst the people of southeast Asia, including Vietnam, Thailand and Cambodia beginning in about 2004. The research experiment was the initial study done on Oseltamivir to judge its effectiveness against the relentless H5N1 influenza variety spreading about Vietnam. They discovered that oseltamivir, also known as tamiflu, significantly augmented the survival rate of the mice in the experiment.</p>
<p>The experiment was paid for and sponsored by the National Institute of Allergy and Infectious Disease [NIAID], which is affiliated with the National Institute of Health [NIH]. Health officials are concerned that the bird flu virus might produce the capability to transmit more easily from human to human and become far more deadly taking millions of lives via a flu pandemic. The point is to learn whether antiviral medications have the strength and endurance to treat and act as a prophylaxis for the avian virus since an early phase outbreak would mean few if anyone would be vaccinated. Once a vaccine becomes viable, months would be needed to produce, deliver and administer it.</p>
<p>Scientists who carried out the study administered one of three daily dosage amounts to the H5N1 contagious mice. The maximum amount was adjusted to the weight of the mice and was the equivalent of the expected dose for humans infected with the illness. The protocol for generic tamiflu is to take it for a course of five days, the also tested an eight day course in 50 percent of the mice. the H5N1 virus continued to spread if the medication was ceased after five days. Generic tamiflu reduces the action of the virus in the mice, inhibiting its ability to spread into uninfected cells by stopping the neuraminidase enzyme, the surface protein which enables the virus to move from infected cells to others.</p>
<p>There were 8-0 mice total infected with the H5N1 virus and twenty of those received a placebo drug, thirty were given tamiflu at one of those three dosage levels for a five day span, while thirty got the dose of one of three levels for an eight day period. None of the placebo group of mice lived. Just five of ten mice who were administered the top level five day dose of tamiflu survived. Oseltamivir did aid in suppressing the flu virus in the infected rodents, the virus continued to thrive if the tamiflu was discontinued after day five.<br />
Those mice that were administered the tamiflu over eight days did do better at surviving. One of the ten mice given a low dose survived as did six of ten in the mid level range of dosage and eight out of ten that were administered the highest dosage amount survived. The eight day course of oseltamivir gave added time for the virus to decrease its levels and there was a lesser chance of the avian virus from bouncing back after the tamiflu medication dosing was closed.</p>
<p>On top of testing for the effective response from the tamiflu versus H5N1 flu virus in these rodents, researchers also evaluated the vigorous nature of the current avian virus from Vietnam to a 1997 strain of the same virus that caused the deaths of half a dozen individuals in Hong Kong. Scientists discovered that The recent H5N1 influenza avian virus now working its way around Vietnam is far more virulent than its previous 1997 counterpart. They are suggesting that a longer phase of tamiflu antiviral medication will likely be necessary to defeat the ferociousness of the antigenic version of the H5N1 bird flu virus.</p>
<p>They believe that H5N1 is going through a quickening redevelopment phase that is tenacious. Experts were taken back by the persistence of this strain of bird flu. This initial study will be useful when future research is conducted by offering up a basis for measurement towards treatment and prevention of the avian virus utilizing oseltamivir – tamiflu antiviral medication.</p>
<p>After a spinal tap procedure on a young Vietnamese victim of influenza H5N1 performed in England physicians found traces of H5N1 in the boy’s spinal fluid which indicates this flu virus has the capability to transmit to the brain. More science is required to determine whether higher doses of tamiflu over a longer course can thwart H5N1 from entering the lungs and establishing a grip so it can then spread to the brain. Animal study models using avian flu virus to closely mimic the illness in a person are planned.</p>
<p>The NIAID is a section of the National Institute of Health connected with the United States Department of Health and Human Services and the NIAID is supportive of basic and practical research in order to diagnose, treat and prevent infectious communicable diseases like influenza, among others.</p>
