Since the first report by Chanock et al.,1 in 1958, on the association of hemadsorption viruses with respiratory illness in childhood, several investigators in this country and abroad2-13 have recovered hemadsorption viruses from the respiratory tracts of children and adults affected by respiratory infections of variable severity. Until recently, the hemadsorption viruses included 2 strains, and it has been proposed that these agents be included in the group termed "parainfluenza viruses."14 A third agent has been isolated from an adult and several children and it has been proposed that it be called "parainfluenza Type 4."15

Although the role of parainfluenza viruses in human disease has not been completely established, there is good evidence that these viruses should be considered as responsible agents of some of the nonbacterial respiratory infections occurring in infants and children.16,17
