Abstract

Studies of parainfluenza virus type 4 (PIV-4) have been limited by difficulty in culturing. We prospectively studied a cohort of 225 young children attending daycare followed for 165 child-years, using polymerase chain reaction to detect 12 viruses, including PIV-4. PIV-4 was second only to PIV-3, occurring in 9 of 87 (10%) PIV+ illnesses. PIV-4 illnesses were not more severe and not associated with a specific clinical syndrome.
