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 understand the prevalence of Clonorchis sinensis in Xinhui District and provide a scientific basis for making prevention and treatment strategies. Methods Stratified stratified random sampling according to different geographical locations, stool samples of Clonorchis sinensis were counted and stained with modified Kato ’s thick smear method. Results A total of 5 005 individuals were investigated in the district, of which 456 were infected with Clonorchis sinensis, with an infection rate of 22.74%. The number of stool egg per gram (EPG) ranged from 24 to 780. The infection rate of males was 26.16%, and the infection rate of females was 19.23%. The difference was statistically significant (χ2 = 13.676, P <0.01). Conclusion The Xinhui District is a highly endemic area of Clonorchis sinensis. It is suggested to strengthen the active monitoring and include screening of Clonorchis sinensis infection screening in the physical examination.
