Influenza virus first was isolated from chickens suffering from fowl plague in 1901 a subtype we now call H7N7. In 1931, an influenza virus closely related to the virus that caused the Great Pandemic of 1918 was identified in swine. The first influenza B virus was isolated in 1940, and the first influenza C virus in 1947. The ability to isolate these viruses and grow them in embryonated eggs eventually led to the ability to develop and test influenza vaccines and antiviral medications, as well as to perform careful seasonal surveillance.
