Epidemiology of parainfluenza virus type 3 in England and Wales over a ten-year period

Abstract

SUMMARYWe have analysed data on respiratory syneytial (RS) and parainfiuenza type 3 (PF3) viruses reported to the Communicable Disease Surveillance Centre. London, over the period 1978–87. These confirm the annual winter epidemic of RS virus and show that, in England and Wales, PF3 is a summer infection with regular yearly epidemics.
