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 global spread of H5N1 influenza in birds is considered a significant pandemic threat. While other H5N1 influenza strains are known, they are significantly different on a genetic level from a highly pathogenic, emergent strain of H5N1, which was able to achieve hitherto unprecedented global spread in 2008.

The World Health Organization (WHO) confirmed on July 26, 2006, that a 17-year-old boy who died on July 24, 2006, in the Phichit province of northern Thailand had H5N1 avian influenza, marking the country's first case this year. H5N1 was recently detected in 31 dead chickens in Phichit province.
Though H5N1 has been circulating nationwide in wild birds, domestic poultry, and mammals since 2022, you may have only been hearing about it recently because of its jump to dairy cattle. The first ...
Dairy industry experts say the virus entered California after local cows were shipped to another state and then returned to California.
There have been 939 cases of human H5N1 infections worldwide as of November 2024, according to the World Health Organization. ... the mutated virus did not appear to pass from those two patients ...
Influenza A/H5N1 was first recorded in a small outbreak among poultry in Scotland [74] in 1959, with numerous outbreaks subsequently in every continent. [75] The first known transmission of A/H5N1 to a human occurred in Hong Kong in 1997, when there was an outbreak of 18 human cases resulting in 6 deaths. It was determined that all the infected ...
While prior H5N1 strains have been known, they were significantly different from the current H5N1 strain on a genetic level, making the global spread of this new strain unprecedented. The current H5N1 strain is a fast-mutating, highly pathogenic avian influenza virus (HPAI) found in multiple bird species. It is both epizootic (an epidemic in ...
