The frequency of episodes of acute rheumatic fever and acute glomerulonephritis in the region about Miami, Fla., was studied by establishing a registry with the cooperation of physicians and hospitals. Monthly reports were obtained over a period of 13 months, during which 17 acute attacks of rheumatic disease and 18 of glomerulonephritis were reported. These low frequencies were striking in view of the fact that group A beta-hemolytic streptococci have been recovered from the throats of more than 40 % of a group of school children between the ages of 6 and 9 years. Autopsies reveal a lower frequency of heart lesions due to rheumatic disease in persons born in Florida than in those born elsewhere. Establishing similar registries in other parts of the country would yield valuable data as to geographic factors in disease.
