Prevalence of streptococcal sorethroat in the school children of Dhaka.

Beta Haemolytic Streptococcal (BHS) infections and their sequelae Rheumatic Fever (RF) and Glomerulonephritis (GN) have a world wide distribution and so pose an important health problem. Reports show that there is considerable variation in the number of isolations from different groups. Present study intended to find out the health status of the school children in relation to streptococcal throat infection, in Dhaka Cantonment. It was a cross sectional, observational study. During one year period total six hundred and one (601) children were examined from one school of Dhaka Cantonment. Prevalence of streptococcus was found to be 22% among the study population with highest rate (67%) for group-G among BHS positive cases. True streptococcal infection was found in 8.7% cases & 2.2% cases were true GABHS positive cases. GABHS was significantly higher in large size families. Females and children from lower socioeconomic group were at higher risk. Females and children of large families may require special attention regarding prevention of streptococcal infection and RF/RHD prevention programme.
