Myint T, Htoon MT, Shwe T. Estimation of leprosy prevalence in Bago and Kawa
townships using two-stage probability proportionate to size sampling technique.
International Journal of Epidemiology 21(4): 778-83, 1992.
Two surveys to estimate leprosy prevalence using two-stage probability
proportionate to size sampling technique were conducted in Bago and Kawa
townships. A total of 3519 and 3739 individuals were examined in each township.
The two surveys were finished within 25 (Bago) and 30 (Kawa) working days at a
cost of Kyats 10,000 (US $1500) for each survey. The estimated leprosy
prevalence obtained in Bago was 9.95 per 1000 population (95% confidence
interval (CI): 7.11-12.78) and in Kawa it was 12.04 per 1000 population (95% CI:
8.85-15.22). A total of 30 (Bago) and 34 (Kawa) new leprosy cases were detected
in the two surveys. Grade I disability was seen to be 20% in Bago and 18.78% in
Kawa, whereas grade II disability was 17.14% in Bago and 15.56% in Kawa.
