Climatic Impacts on Japanese Encephalitis, Three Gorges Dam, China

by Sarah King

Japanese encephalitis (JE) is a prevalent, mosquito-borne infectious disease found throughout the Asian Pacific Rim and Southeast Asia and most predominately in China (Bai et al. 2014). The Chinese province Chongqing has one of the highest incidence rates of JE in the country in combination with only four other provinces, make up 50% of the incidence of JE in all of China, with only 26% of the population. Consequently, Chongqing is an interesting place to study the effect of climatic change on Japanese encephalitis, which is exactly what Yuntao Bai and his colleagues did. Bai and his team set out to identify the most important climatic variables that induce the transmission and spread of the JE virus in Chongqing from 1997–2008, and what kind of geographical incidence patters arise in relation to climate change (Bai et al., 2014).
