title: The Tecumseh study. XII. Enteric agents in the community, 1976-1981.
abstract: Enteric illnesses in residents of Tecumseh, Michigan, were studied from 1976 to 1981. The frequency of illness among adults and children increased each year in the late autumn, usually in November. This peak of illness preceded the main period of appearance of the rotaviruses, which were less regularly associated with another peak of illness. Rotaviruses were identified in 3.8% of all stool specimens collected; in specimens from children under two years of age, the annual rate of rotavirus identification was 10.4%. All rotaviruses were identified during the period from late December to early April. Bacterial pathogens were isolated from 3.3% of stool specimens, with no concentration in any age group or season. However, most enteric illnesses in the community were not associated with recognized pathogens. Testing of blood specimens collected in 1976-1978 by complement fixation confirmed the seasonal pattern of rotavirus activity. Rotavirus infections were documented in all age groups, even in older adults, and were associated with symptomatic illness.
