Natural environment and schistosomiasis transmission in Poyang Lake re-gion / 中国血吸虫病防治杂志

ABSTRACT

Schistosomiasis is closely related to natural environmental factors. The changes of environmental factors such as temperature hydrology vegetation soil etc. all impact the scope and extent of schistosomiasis transmission. Poyang Lake is the largest freshwater lake and one of the major endemic areas with schistosomiasis in China. With global warming the imple-mentation of the Three Gorges Dam operation and the Poyang Lake Ecological Economic Planning the natural environment in Poyang Lake area has been and will continue to change especially the water environment and climate environment which are more closely related to the schistosomiasis transmission. These changes to some extent have affected and will continue to affect the prevalence and transmission of schistosomiasis. This article reviews the relationship between the natural environment and its changes and schistosomiasis transmission in the Poyang Lake region.
