To lessen your risk of becoming infected with
bird flu

• Avoid contact with live chickens and ducks - even
  ones that appear healthy.
• Avoid contact with dead birds.
• Avoid contact with items or surfaces
• that may have been contaminated with
• excrement from an infected bird.
• All foods from poultry, including eggs,
• should be thoroughly cooked.
• As with other infectious illnesses, one of the
  most important preventive practices is careful
  and frequent hand washing.
• Watch for symptoms such as a fever, difficulty
  breathing, cough, or any illness that requires
  prompt medical attention.

• Since December 2003, highly pathogenic H5N1
  avian influenza viruses have swept through
  poultry populations across Asia and parts of
  Europe. The outbreaks are historically
  unprecedented in scale and geographical spread.
  Their economic impact on the agricultural sector
  of the affected countries has been large. From
  December 2003 to mid-July 2005, outbreaks of
  avian influenza A(H5N1) in poultry occurred in
  nine countries (Cambodia, China, Indonesia,
  Japan, the Republic of Korea, the Lao People's
  Democratic Republic, Malaysia, Thailand and Viet
  Nam).

Since late July 2005, outbreaks in domestic
poultry as well as wild birds have been reported
in the Russian Federation, Kazakhstan and
Mongolia. Outbreaks have recurred despite
aggressive control measures, including the
culling of more than 140 million poultry as of
September 2005.

• Human cases, with an overall fatality rate around
  50, have been reported in Cambodia, Indonesia,
  Thailand and Viet Nam. The majority of human
  infections occur sporadically. Increased
  infection of humans comes in winter months,
  November to March, with a smaller increase around
  July to September. Almost all human infections
  can be linked to contact with infected poultry,
  but isolated instances of inefficient
  human-to-human transmission may have occurred in
  Viet Nam in 2004, and possibly in Thailand and
  Indonesia.
