Reye syndrome in Ohio, 1973-1977.

Some major epidemiologic features of Reye syndrome have been elucidated since the first description of this clinical entity. Multiple studies have shown an association with epidemic influenza B and endemic varicella. Little population data are available on age, sex, race, geographic distribution, and secular trends. A five-year retrospective population-based study of 190 Ohio residents diagnosed with Reye syndrome from January 1, 1973-December 31, 1977, is reported here. The temporal relationships between the occurrence of Reye syndrome and influenza B and varicella were confirmed; however, a high number of blacks and city dwellers with Reye syndrome were found in this study.
