Acute respiratory disease of university students with special reference to the etiologic role of Herpesvirus hominis.
Infections with Herpesvirus hominis type 1 were associated with 11.5% of acute respiratory illnesses of university students who were admitted to the student infirmary over a 6-year period. Over three-quarters of these infections were detected in students with pharyngitis or tonsillitis; 42% had ulcerated lesions on tonsils or posterior pharynx but only 11% had lesions in the anterior portion of the mouth or lips. Almost all of the H. hominis infections were accompanied by significant rises in neutralizing antibodies and few students had detectable antibodies in the initial serum collected during the acute phase of illness. Special studies revealed herpes-specific IgM antibodies in the early convalescent sera of some of these patients. The data demonstrate that 80% of the infections detected were primary infections with H. hominis. Only 30% of university students possessed neutralizing antibodies to H. hominis and about 10% of those without antibodies acquired antibodies each year. These data suggest that the majority of persons from middle income families reach young adulthood without acquiring infections of H. hominis and the spread of the virus requires close and intimate contact.
