[Surveillance of schistosomiasis in Hubei section of the Three Gorge Reservoir areas, 2007 - 2009].

ABSTRACT

The source of infection of schistosomiasis and snail situation in Hubei section of the Three Gorge Reservoir areas from 2007 to 2009 were investigated by combined epidemiological, immunological and field survey. The results showed that there were no local residents and livestock infected with shchistosome, and no Oncomelania snails were found, but 4 cases of imported patients with chronic schistosomiasis were checked out. It is suggested that the surveillance and intervention should be strengthened pointing to the risk of schistosomiasis transmission in the Three Gorge Reservoir areas, so as to prevent schistosomiasis being endemic in these areas.
