New Scientist said that an H5N1 virus infecting a human could acquire all the abilities it needs to become a pandemic virus by swapping genes with a human virus infecting the same individual. [ 100 ] On December 6, the USDA announced a new mandate to test the national milk supply for bird flu as part of efforts to combat the virus's spread ...
The epicenters of both the Asian influenza pandemic of 1957 and the Hong Kong influenza pandemic of 1968 were in Southeast Asia, and it is in this region that multiple clades of H5N1 influenza virus have already emerged. The Asian H5N1 virus was first detected in Guangdong Province, China, in 1996, when it killed some geese, but it received ...
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]
The bird flu that’s been making news in the United States is a virus called H5N1. Some flu viruses carried by birds cause only mild infections and are classified as low-pathogenic viruses.
Could H5N1 bird flu become airborne and spread between people? Scientists say that’s still unknown. But, if the virus gains that ability, it could produce the next pandemic. The virus has been ...
When, where and how the H5N1 bird flu virus may evolve and its capacity to spark a pandemic is hard to predict — in part, some researchers say, because of federal restrictions on gain-of ...
H5N1 pre-pandemic vaccines exist in quantities sufficient to inoculate a few million people [4] and might be useful for priming to "boost the immune response to a different H5N1 vaccine tailor-made years later to thwart an emerging pandemic". [5] H5N1 pandemic vaccines and technologies to rapidly create them are in the H5N1 clinical trials ...
H5N1 influenza virus is a type of influenza A virus which mostly infects birds. H5N1 flu is a concern because its global spread may constitute a pandemic threat. The yardstick for human mortality from H5N1 is the case-fatality rate (CFR); the ratio of the number of confirmed human deaths resulting from infection of H5N1 to the number of those confirmed cases of infection with the virus.
