The risk of humans getting bird flu is still low, but you can take the following steps to lower your risk: Avoid contact with sick or dead birds. Wash hands thoroughly after touching poultry.
The threat of avian flu has dominated public health discourse as cases become increasingly more widespread and severe. H5N1, a highly pathogenic strain, was present in several continents as early ...
Avian flu has been around and infecting wild birds and poultry since 1996. There have been nearly 1,000 known cases of bird flu in humans (889 between 2003 and May 3, 2024, according to the World ...
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. [2] [3]
Bird flu can be transmitted from birds to humans if they come in close contact with infected animals. According to experts, infected birds shed flu viruses in their saliva, mucous, and feces.
The PB1 gene codes for the PB1 protein and the PB1-F2 protein. The PB1-F2 protein probably contributes to viral pathogenicity and might have an important role in determining the severity of pandemic influenza. Until H5N1, all known avian influenza viruses had a Glu at position 627, while all human influenza viruses had a lysine.
Avian flu virus can last indefinitely at a temperature dozens of degrees below freezing, as is found in the northernmost areas that migratory birds frequent. [citation needed] Heat kills H5N1 (i.e. inactivates the virus). Influenza A viruses can survive: Over 30 days at 0 °C (32.0 °F) (over one month at freezing temperature)
The CDC says no person-to-person spread of H5 bird flu has been detected and is using its flu surveillance systems to monitor for H5 bird flu activity in people. Since March 2024, 901 dairy herds ...
