Survey of Clonorchis sinensis Infection in Miaoli County, Taiwan
1994 Vol.10 NO.1
Clonorchis sinensis is more prevalent in mainland China, Japan, Korea, Vietnam, Taiwan and the southeast Asian countries(1,2). Since the first report by Ohoi(3) in 1915 on the infection in Taiwan, there have been several reports suggesting that some townships or villages in Taiwan are high infection areas. The infection rates in high infection areas such as the Sun-Moon Lake area of Nantou County, Meinong and Chishan townships of Kaohsiung County, Chuwei, Toulun and Hsintien villages of Pingtung County, and Shitan Township and Miaoli City of Miaoli County are estimated to be between 10 and 50%(4-10). Cross(11) in his 1969 report estimated the infection rate of Clonorchis sinensis in man in Taiwan area at 1.5%. Now that most helminthes have been brought under control in Taiwan, the infection of Clonorchis sinensis has become more significant.
