Rheumatic fever in children and adolescents in Hawaii.

Case records of hospitalized children (age 4 to 18 years) with acute rheumatic fever on Oahu, HI, were reviewed for the 4-year period from Oct 1, 1980, to Sept 30, 1984. Ninety-eight cases met the modified Jones criteria. The overall incidence of rheumatic fever was 13.4 hospitalized children per 100,000 children per year and that for recurrent attacks was 2.5. Of the 98 with rheumatic fever, 73 had polyarthritis, 33 had carditis, and ten had chorea. Polynesian/part-Polynesian children accounted for 76 of the 98 cases. The incidence of rheumatic fever in Hawaiian/part-Hawaiian was 18.0 and for Samoan children was 206 hospitalized children per 100,000 per year. The relative risks were 7.7 and 88 times that of the white children, respectively. Rheumatic fever continues to cause significant morbidity in children in Hawaii, especially in Polynesian children.
