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]
Future flu pandemics, which may be caused by an influenza virus of avian origin, [35] are viewed as almost inevitable, and increased globalization has made it easier for a pandemic virus to spread, [34] so there are continual efforts to prepare for future pandemics [76] and improve the prevention and treatment of influenza.

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.
Bird flu can be diagnosed by testing samples taken from a sick person’s nose, throat, or eye, but testing is primarily recommended for people who have symptoms and have been recently exposed to ...
