RESEARCH ON THE CAUSES AND PREVENTION OF SCHISTOSOMIASIS IN DIFFERENT TYPES OF ENDEMIC AREAS IN DONGTING LAKE AREA SINCE 1949
Since 1949,research on schistosomiasis control in the Dongting Lake area has mainly centered on the lake-marsh type and the hill type.The formation of both lake-marsh and hill-type schistosomiasis can be at-tributed to the following reasons:people in the two different types of endemic areas are not accustomed to doing personal protection when they go fishing and come into contact with the infected water;subjective consciousness of schistosomiasis is neglected,and the sense of protection is weak;and there is obvious seasonality in the cli-mate,which leads to the surge of the number of people who play the grass in the lake and go fishing during the period of abundant water.Of course,due to the different geographic environments of the two types of endemic areas,there are also differences in the density of snails,policy orientation and measures taken to eliminate schis-tosomiasis.Therefore,the study of schistosomiasis control in different types of endemic areas in Dongting Lake,Hunan,aims to provide historical lessons for contemporary epidemic prevention and treatment.
