Influenza A virus
The type species of the genus INFLUENZAVIRUS A that causes influenza and other diseases in humans and animals. Antigenic variation occurs frequently between strains, allowing classification into subtypes and variants. Transmission is usually by aerosol (human and most non-aquatic hosts) or waterborne (ducks). Infected birds shed the virus in their saliva, nasal secretions, and feces.
Kazakhstan
I'm sorry for any confusion, but "Kazakhstan" is not a medical term and does not have a medical definition; it is the name of a country located in Central Asia, known officially as the Republic of Kazakhstan.
