Temperature, nearby species could affect avian flu transmission in migrating birds

Finding a turkey this holiday season could be difficult because of avian flu outbreaks on farms. Migratory wild birds could be to blame for transmitting the virus to commercial flocks, but no one has looked closely at this wandering population until now. Researchers now report that cooler temperatures and certain species gathering in the same winter habitat could increase the circulation of H7 and H9 strains.
