Avian influenza, also known as avian flu or bird flu, is a disease caused by the influenza A virus, which primarily affects birds but can sometimes affect mammals including humans. [1] Wild aquatic birds are the primary host of the influenza A virus, which is enzootic (continually present) in many bird populations.
This is a timeline of influenza, briefly describing major events such as outbreaks, epidemics, pandemics, discoveries and developments of vaccines.In addition to specific year/period-related events, there is the seasonal flu that kills between 250,000 and 500,000 people every year and has claimed between 340 million and 1 billion human lives throughout history.
Influenza A virus subtype H5N1 (A/H5N1) is a subtype of the influenza A virus, which causes the disease avian influenza (often referred to as "bird flu"). It is enzootic (maintained in the population) in many bird populations, and also panzootic (affecting animals of many species over a wide area). [ 1 ]
Migratory birds can spread influenza across long distances. An example of this was when an H5N1 strain in 2005 infected birds at Qinghai Lake, China, which is a stopover and breeding site for many migratory birds, subsequently spreading the virus to more than 20 countries across Asia, Europe, and the Middle East.
As of the July 25, 2008 FAO Avian Influenza Disease Emergency Situation Update, H5N1 pathogenicity is continuing to gradually rise in wild birds in endemic areas but the avian influenza disease situation in farmed birds is being held in check by vaccination. Eleven outbreaks of H5N1 were reported worldwide in June 2008 in five countries (China ...
Thousands of birds and animals were being culled in Germany to stop the spread. [11] In the United Kingdom the flu was found in a wild duck at a turkey farm in Lincolnshire. [12] In South Korea, a record total of 18.4 million birds had been killed by December since the first outbreak of avian flu was reported at a farm on Nov. 18. [13]
The 1889–1890 pandemic, often referred to as the Asiatic flu [53] or Russian flu, killed about 1 million people [54] [55] out of a world population of about 1.5 billion. It was long believed to be caused by an influenza A subtype (most often H2N2), but recent analysis largely brought on by the 2002-2004 SARS outbreak and the COVID-19 pandemic ...
