Examination of 267.107 liver specimens obtained in Brazil by viscerotomy during from 1937 to 1946 inclusive revealed 5,953 Schistosoma mansoni infe¬ctions. This represents 2.23% ± 0.019 of the total number of livers studied. Data on the incidence of the disease is tabulated by states and municipios. Infected livers were found in all of the states and territories except the Territory of Amapá. Schistosomiasis is widespread in Brazil with highest incidence in the states of the Northeast. The disease is quite common in Espírito Santo and Minas Gerais as well. A study of the age distribution of cases of intestinal schistosomiasis observed among liver specimens obtained in the year 1938 showed a low inci¬dence on young children with a peak of prevalence in the 10 to 19 year age group. The purpose of this contribution is to call attention of the health autho¬rities to the extent and gravity of the problem of intestinal schistosomiasis in Brazil.
