OBJECTIVE: To investigate the risk factors of schistosomiasis transmission in Jingmen City.
METHODS: The Oncomelania hupensis snails, the wild animal feces, and infection source were selected as the monitoring objects to carry out the schistosomiasis risk monitoring. I-III levels of risk environments were treated with appropriate measures.
RESULTS: A total of 52 environments and three water systems were monitored and 1 542 snails were dissected but no Schistosoma infected snails were found. Nine fecal samples were collected from the areas with snails, and no eggs of Schistosoma were found. Eighty-nine samples of cattle/sheep faces, and mice and dogs were collected, and three samples of cattle feces were found with Schistosoma eggs. Five environments were assessed as Grade II, and 48 environments were assessed as Grade III, and 2 environments were assessed as no risk of schistosomiasis transmission.
CONCLUSIONS: In Jingmen City, the mollusciciding work from May to June could decrease the density of snails and the risk of schistosomiasis transmission efficiently. The schistosome-infected cattle were the main infection source, and therefore, the cattle and snails should be administrated simultaneously.
