Prevalence rates of leprosy in Cambodia; results of a sample survey.

A total population survey was carried out in early 1994 in 13 villages around Battambang (northwest Cambodia). Coverage was 87.5% (12,992 out of 14,842). Among the 12,922 household members examined 21 known patients and 20 new patients were found. Five of the 21 known and none of the newly found patients had disabilities. Among males total prevalence rates (known and newly found patients combined) appear to rise up to the age of 25 to 34, after which rates remain roughly stable until they start to decline in the 65 to 74-year age group. Among females prevalence rates reach a plateau in the 35 to 44-year age group.
