In December, a HPAI H5N1 subtype of clade 2.3.4.4b was found in a captive Asian black bear and in wild and captive birds in a wildlife park in France. [17] A human case of H5N1 was reported in the U.S. in April, "though this detection may have been the result of contamination of the nasal passages with the virus rather than actual infection."
The U.S. Centers for Disease Control and Prevention (CDC) says handling infected birds is unlikely to lead to illness in people. However, there have been 67 human cases of bird flu since 2022 ...
Additionally, the new outbreaks of HPAI in poultry and wild birds in Russia, Kazakhstan, Western China and Mongolia may indicate that migratory birds probably act as carriers for the transport of HPAI over longer distances. Short-distance transmission between farms, villages or contaminated local water bodies is likewise a distinct possibility.
Between 1959 and 1995, there were 15 recorded outbreaks of highly pathogenic avian influenza (HPAI) in poultry, with losses varying from a few birds on a single farm to many millions.

Influenza A/H5N1 was first detected in 1959 after an outbreak of highly pathogenic avian influenza in Scotland, which infected two flocks of chickens. [59] [60] The next detection, and the earliest infection of humans by H5N1, was an epizootic (an epidemic in nonhumans) of H5N1 influenza in Hong Kong's poultry population in 1997. This outbreak ...
The CDC estimates that there have been at least 9.1 million illnesses, with 110,000 hospitalizations for adults. It’s also estimated that 4,700 people have died from flu this season.
The Asian H5N1 virus was first detected in Guangdong Province, China, in 1996, when it killed some geese, but it received little attention until it spread through live-poultry markets in Hong Kong to humans in May 1997, killing 6 of 18 infected people. [...] From 1997 to May 2005, H5N1 viruses were largely confined to Southeast Asia, but after ...
