GEOGRAPHIC EPIDEMIOLOGY OF SARCOIDOSIS IN DENMARK - 1954-1957

Abstract

The incidence of pulmonary sarcoidosis in Denmark during 1954-1957 was obtained from the number of cases reported by chest clinics in individual countries. Approximately 900 cases were reported, corresponding to an average annual rate of 55 per million. The incidence was uniform in different regions of Denmark except for a greater part of Jutland where the rate was 3 times as high as in the rest of the country. There was no correlation between the geographic pattern of sarcoidosis and coniferous forests, and none was found with the tuberculin pattern in the general population as shown by the participants in the mass campaign of 1950-1952 who were 15 to 34 years of age; the geographic tuberculin pattern in cattle in 1937; or the geographic pattern for the incidence of pulmonary tuberculosis in 1955.
