RESUMEN
The paper is a report of sociological investigation about thousands of peoples who were exposed to acute infection of schistosomiasis in subdistrict Younyuan, Wuhan City. 9 organizations, 258 families (944 persons) were surveyed with sociological metheds such as outlined questionare, personal questioning, visit and meeting. The result showed that some factors (age, profession, cultural level, size of residing place, distance between residing place and Yangtze river, frequency of swimming in river) were closely related with the epidemic outbreak of acute schistosomiasis. Thus we suggest that public health education should be implemented as an important antischistcsomiasis measure for local residents in urban epidemic areas when snail host (Oncomelania hupensis) of Schistosoma japonicum has not been controlled.
