Abstract
A survey of secondary schools in Karachi, Pakistan, was conducted to assess the prevalence rate of rheumatic and congenital heart disease; 4,002 boys and girls between the ages of 8–14 years were examined. By standardized and well accepted criteria, 3.5 per 1,000 were found to have heart disease, 1.8 per 1,000 each for congenital and rheumatic heart disease. Throat cultures positive for beta hemolytic streptococci were found in 4.2 per cent of the same sample. Comparison of this prevalence with that reported from other parts of the world suggests that rheumatic fever and rheumatic heart disease are essentially as common in Pakistan as in temperate and affluent nations.
