Surveys on the infection rate of the clonorchiasis in Xinhui district,Jiangmen city

目的了解新会区华支睾吸虫病的流行现状,为制定防治策略提供科学依据。方法按不同地理位置进行分层随机抽样,用改良加藤氏厚涂片法粪检华支睾吸虫卵并计数。结果全区共调查5个点2 005人,其中感染华支睾吸虫456人,感染率为22.74%,每克粪便虫卵数（EPG）为24~780个。男性感染率为26.16%,女性感染率为19.23%,差异有统计学意义（χ2=13.676,P〈0.01）。结论新会区为华支睾吸虫病高度流行区,建议加强主动监测,将华支睾吸虫感染筛查列入体检项目。

Objective To study the epidemic situation of clonorchiasis in Xinhui district, and therefore provide a scientific basis for the development of prevention strategies. Methods Samples were collected according to stratified random sampling from different locations. The modified Kato＇s thick smear method was used to examine the ova of the Clonorchis sinensis from the feces. Results 2005 samples from 5 locations in the district were tested. 456 samples were testified to be infected by Clonorchis sinensis, with the infection rate of 22.74%. The number of the eggs from one gram of the feces was from 24 to 780. The infection rate was 26.16% for male, and 19.23% for female. This result indicates that the difference of the infection rates is statistically significant（x^2=13.676,P〈0.01）. Conclusion On the basis of the survey, the clonorchiasis is considered to be endemic in Xinhui district, and the active surveillance should be strengthened. It is suggested screening for Clonorchis sinensis infection should be listed on the body check program.
