Avian Influenza Brief

  1. 1. Team Palehorse Avian Influenza Brief
  2. 2. Avian Influenza Statistics <ul><li>Avian Influenza A/(H5N1) Cumulative Number of Confirmed Human Cases as of January 7, 2006 </li></ul>RANK GEOGRAPHIC AREA NUMBER Global 146 1 Viet Nam 93 2 Thailand 22 3 Indonesia 16 4 China 7 5 Turkey 4
  3. 3. Background <ul><li>A/(H5N1) Influenza (Avian Influenza) </li></ul><ul><ul><li>Type (A) influenzas are responsible for lethal pandemics </li></ul></ul><ul><ul><li>Subtype H5 N1 is the most virulent to birds influenza virus </li></ul></ul><ul><ul><ul><li>The subtype sickens and kills birds sometimes in a single day. </li></ul></ul></ul><ul><ul><ul><li>Humans and pigs are also known to be susceptible to this virus subtype. </li></ul></ul></ul><ul><ul><ul><li>This virus subtype mutates rapidly. It can massively shuffle and rearrange its genetic material directly in both humans and pigs, making the species more susceptible with every mutation. </li></ul></ul></ul><ul><li>Transmission </li></ul><ul><ul><li>The virus is transmitted through direct contact with sick birds or with surfaces contaminated by their feathers, saliva, or droppings. </li></ul></ul><ul><ul><li>Presently there is only limited human-to-human transmission of the bird flu. </li></ul></ul><ul><ul><li>Young children appear to be especially vulnerable to the virus. </li></ul></ul><ul><ul><li>Outbreaks would likely spread through open air markets, contaminated clothing and equipment, and smuggled birds. </li></ul></ul><ul><li>Virulence </li></ul><ul><ul><li>The virus kills close to 100% of susceptible birds and more than half of infected people. </li></ul></ul><ul><ul><li>The virus potential to combine with a human flu virus makes it a likely source of a widespread pandemic. </li></ul></ul><ul><ul><li>Illness seems to develop within one to five days of exposure to the virus. </li></ul></ul>
  4. 4. Preventive Medicine <ul><li>Signs and symptoms </li></ul><ul><ul><li>Cough, fever, sore throat, muscle aches are the most common symptoms. </li></ul></ul><ul><ul><li>Sometimes the only indication of the disease is a mild eye infection. </li></ul></ul><ul><ul><li>The most virulent form of the virus causes life-threatening complications such as viral pneumonia and acute respiratory distress (the most common causes of bird flu mortalities). </li></ul></ul><ul><li>Preventive Medicine Recommendations </li></ul><ul><ul><li>Avoid domesticated birds. </li></ul></ul><ul><ul><li>Avoid open-air markets. </li></ul></ul><ul><ul><li>Wash your hands. !!!HANDWASHING!!! </li></ul></ul><ul><ul><li>Steer clear of raw eggs. </li></ul></ul><ul><ul><li>Ask for a flu shot (reduces the risk of simultaneous infection with bird and human flu viruses). </li></ul></ul><ul><ul><li>Carefully and thoroughly wash cutting boards, utensils, and all food preparation surfaces in hot, soapy water. </li></ul></ul><ul><ul><li>Thoroughly cook poultry until juices run clear and meat reaches an internal temperature of 180°F. </li></ul></ul><ul><ul><li>Although there is no evidence that bird flu can be transmitted to cats and dogs, WTF was seen eating dead birds. WTF may infect personnel without contracting the disease or exhibiting signs of illness. </li></ul></ul><ul><ul><ul><li>We need to act on this health threat quickly and swiftly (without necessarily killing the dog). </li></ul></ul></ul><ul><li>Treatment </li></ul><ul><ul><li>A prototype French vaccine is currently being tested. </li></ul></ul><ul><ul><li>The vaccine won’t be licensed until late in 2006. </li></ul></ul><ul><ul><li>Once licensed, it will take 6 to 12 months of production before useful amounts of the vaccine are available. </li></ul></ul><ul><ul><li>Right now the primary treatment option is the flu drug oseltamivir (Tamiflu). </li></ul></ul>
