Genera "Host Range"

Influenza virus A and B "Influenza A viruses naturally infect man, and several other mammalian species and a wide variety of avian species. Some interspecies transmission believed to occur.

Influenza B strains appear to naturally infect only man and cause epidemics every few years. They also artificially infect laboratory rodents." (B72)

Influenza virus C "Infection of man is common in childhood. Occasional outbreaks, but not epidemics, have been detected. Swine in China reported to be infected by viruses similar to contemporary human strains" (B72)
