ABSTRACT
The paper presents the morbidity through streptococcal angina, acute rheumatic fever and acute glomerulonephritis in two industrial enterprises with different working conditions. This study was performed between 1968 and 1977. In enterprise A, where rheumatogenic conditions were present, streptococcal angina had an yearly attacks vaeried between 0,13 and 0,7 percent, and acute glomerulonephritis between 2,3 and 5,4 percent. In enterprise B, with usual working conditions, angina showed an yearly variation between 2,3 and 5,8 percent, acute rheumatic fever varied between 0,0 and 0,84 percent and there were no cases of acute glomerulonephritis. In two units (collectivities of students) where angina was detected by active methods and prophylactic measures were applied rigurously no post-streptococcal complications were recorded. The authors stress the effects of morbidity through streptococcal infections in adults and recommend an extension of targeted prophylactic programs in high-risk units.
