title: Isolation of H1N1 influenza virus in Munich.
abstract: During an outbreak of a mild upper respiratory tract infection in a university children's hospital in Munich, an H1N1 influenza virus was isolated. Serological analysis of the isolate showed that antigenically the virus resembled the USSR/90/77 strain of influenza A virus which has been isolated in many parts of the world during the last two years.
