[Surveillance of endemic situation of schistosomiasis in Gaoyou sections in east route of South-to-North Water Diversion Project before water transfer].

Objective: To understand the endemic situation of schistosomiasis and the distribution of Oncomelania hupensis snails in Gaoyou sections in the east route of the South-to-North Water Diversion Project before water transfer.

Methods: The Grand Canal, the Sanyang River and the range of 3 kilometers of both sides of the rivers were chosen as the surveillance area in the Gaoyou sections in the east route of the South-to-North Water Diversion Project, and the Gaoyou Lake area adjacent to the east route was also chosen as the surveillance area. The human and livestock schistosomiasis and Oncomelania hupensis snails were monitored by the conventional method.

[Investigation on HBsAg carrier rate of population in schistosomiasis transmission-interrupted area of Gaoyou City, 2010].

A total of 500 residents in a schistosomiasis transmission-interrupted area, Maogang Village of Gaoyou City were detected simultaneously for the infection status of schistosome and HBV, and the results showed that there was no significant difference between the HBsAg carrier rates of residents with and without the history of schistosomiasis, but the HBsAg carrier rates in some population were high, which needs more concern.
