[Circulation of parainfluenza viruses and adenoviruses in groups exposed to the action of noxious chemicals or not].

Investigations were conducted during 1985 and 1986 years on the effect of some chemicals on the parainfluenza and adenovirus circulation in an industrial enterprise community. The presence of type 1, 2 and 3 parainfluenza virus and of adenovirus was revealed by immunofluorescence in exfoliated cells collected from nasopharynx. The kinetic of specific hemagglutination inhibiting and complement fixing antibodies was followed monthly by immunological tests. Meaning of the results is discussed from an epidemiological point of view.
