The human incubation period of avian influenza A (H5N1) is 2 to 17 days. [37] Once infected, the virus can spread by cell-to-cell contact, bypassing receptors. So even if a strain is very hard to initially catch, once infected, it spreads rapidly within a body. [ 38 ]
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.
Because of that, both avian and mammalian influenza viruses can infect pigs. If co-infection occurs, reassortment is possible. [20] A notable example of this was the reassortment of a swine, avian, and human influenza virus that caused the 2009 flu pandemic. [20] [4] Spillover events from humans to pigs appear to be more common than from pigs ...

Mammalian influenza viruses tend to be labile, but can survive several hours in mucus. [57] Avian influenza virus can survive for 100 days in distilled water at room temperature, and 200 days at 17 °C (63 °F). The avian virus is inactivated more quickly in manure, but can survive for up to two weeks in feces on cages.
Bird flu is a scary illness with a high mortality rate. But so far, infections in the U.S. have been relatively mild—until now. A patient in Louisiana has been hospitalized with a severe case of ...
