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) |
