Epidemiology of acute rheumatic fever in a multiethnic, multiracial urban community: The miami-dade county experience

Abstract

During the mid-1980s, several US communities experienced outbreaks of acute rheumatic fever (ARF), often involving predominantly white, middle-class individuals living in suburban or rural settings. The medical records of all patients diagnosed with ARF in Miami-Dade County, Florida, between 1984 and 1988 were reviewed. Thirty-five cases met the revised Jones criteria and were considered definite; four additional cases were classified as probable. Carditis was present in 54%. Of the 39 patients, 32 (82%) were black. The annual incidence of ARF among black children aged 5-14 years was 12.25 per 100,000 compared to 0.71 for other (non-Hispanic white plus Hispanic) children (P < .001). ARF was centered in the inner city, where the incidence among black children reached 15.21. Despite the multiethnic, multiracial character of Miami-Dade County and the rapid influx of immigrants, ARF in this community remains primarily a disease of underprivileged, black inner-city children.
