OBJECTIVE
To understand the changes of epidemic situation of schistosomiasis in Shashi District, Jingzhou City.


METHODS
From 2005 to 2010, each year, from April to May, thestatus of Oncomelania snails were investigate by using the systematic sampling approach; in October, the inhabitants aged over 6 years were screened by indirect hemagglutination assay (IHA) and the positive persons received the etiological examination (Kato-Katz technique). All the farm cattle in pens were examined by using the plastic cup jacking hatching method. The data of control measures, and the nature and society data were collected annually. All the data were analyzed systematically.

The area with snails, the appearance rate of frames with living snails, and the average density of living snails assumed ascend trends.
