Surveillance of schistosomiasis in Hubei Province in 2014

OBJECTIVE: To analyze the surveillance results of schistosomiasis and understand the transmission situation in Hubei Province in 2014. METHODS: According to the Scheme of Schistosomiasis Surveillance in Hubei Province (the 2009 edition), 207 endemic sites were selected, where the schistosome infections of residents and livestock, and the distribution of Oncomelania hupensis snails were investigated. RESULTS: In the 207 sites, there were 27 sites without positive results of the blood tests and 129 sites without positive results of the stool tests. The infection rates of residents and cattle were 0.17% and 0, respectively. The density of living snails was 0.339 3 snails/0.1m2, the rate of living snails was 10.12%, and the infection rate of snails was 0. The infection rate of residents in the inner embankment type was 0.22%, higher than the rates in the other types. In different age groups, the infection rate in the 50-59 years age group was higher than the rates in other age groups. The infection rates of residents in farmer and fisherman were higher than those in the other occupation groups. The infection rate of floating people was 0, and no acute schistosomiasis patients were found. CONCLUSIONS: The endemic situation of schistosomiasis has decreased obviously in Hubei Province, and the whole province has achieved the criteria for transmission control of schistosomiasis.
