An epidemiological survey for scabies was conducted in a rural community of 2771 persons among 404 households living in 238 houses. Prevalence rates were 13% by population and 30.9% by household. Each index case was responsible, on average, for the spread of infection to 1.9 persons in affected households. Significantly lower rates of secondary attack and transmissibility were observed among the more prosperous villagers. The proportion of infected households increased linearly with household size. The prevalence was highest in those aged up to 19 years, both sexes being affected equally. An average morbidity duration for scabies was 64.5 days; 16.3% of the patients showed secondary pyogenic infection of the skin.
在一个由238所房屋中的404户家庭组成、共2771人的农村社区进行了疥疮流行病学调查。按人口计算的患病率为13%，按家庭计算为30.9%。在受影响的家庭中，每个索引病例平均致使1.9人感染。在较富裕的村民中，继发感染率和传播率显著较低。受感染家庭的比例随家庭规模呈线性增加。19岁及以下人群的患病率最高，男女受影响程度相同。疥疮的平均发病持续时间为64.5天；16.3%的患者出现皮肤继发性化脓性感染。
