NON-POLIO ENTEROVIRUS DISEASE IN THE UNITED-STATES, 1971-1975

Reports to the Center for Disease Control [Atlanta, Georgia, USA] on isolation of non-polio enteroviruses for the years 1971-1975 were analyzed. During 5 yr, enterovirus isolations were reported from 7075 individuals. Of these, 90% occurred in the 7 mo. interval of May-Nov. Enteroviruses were isolated more frequently from males than females for all age groups during all 5 yr. The incidence of reported isolations decreased with increasing age, and an inverse relationship between severity of disease and age was suggested. Clinical diagnoses associated with enteroviral isolations included aseptic meningitis, encephalitis, upper respiratory tract disease, non-specific febrile illness, gastroenteritis, pneumonia and lower respiratory tract disease, exanthem and enanthem.
