Epidemiology of herpesvirus and respiratory virus infections. Part 1. Serologic findings.

The majority of the population group studied had complement-fixation antibodies toward the following viruses: influenza type A, respiratory syncytial, cytomegalovirus, and Epstein-Barr. The herpesvirus infections (cytomegalovirus and Epstein-Barr virus) seemed to be prevalent. Only low incidences of antibodies were found toward adenovirus, influenza type B, influenza type C, and parainfluenza type II. A total of 70 aucte virus infections (increases of antibody titer) were diagnosed in 49 patients. Besides cytomegalovirus, no particular virus infection occurred in a large number. Only 11 of the 70 acute virus infections diagnosed serologically were accompanied by clinical signs of disease
