目的了解湖北省电力系统职工血吸虫病感染状况,为评价和制定防治策略提供依据。方法用血清免疫学方法,从34051名受检者血清中筛查日本血吸虫病阳性病例;阳性者用B超检查肝脏病变。结果34051名受检者血清中筛查出日本血吸虫病阳性者775例,感染率为2.28%。其中,荆州地区的感染率最高,为7.15%;除武汉市以外,其他接受调查的各地级市电力系统职工也有不同程度的血吸虫感染,但感染率均低于2%。对血清阳性者进一步作B超检查发现,血吸虫肝病者419人,占阳性人数的54.1%。与2004年的调查结果相比,各地的血吸虫病感染率有明显下降。结论湖北省电力系统职工血吸虫病防治工作效果明显,但还须加强。
Objective To understand the status of schistosomiasis infection in power system workers in Hubei Province, and to provide basis for evaluation and formulation of prevention and treatment strategies. Methods Serum immunological method was used to screen the positive cases of schistosomiasis japonica from the serums of 34,051 subjects, while the positive ones were examined by B ultrasound. Results A total of 7,505 cases of schistosomiasis japonica were screened from 34051 subjects, the infection rate was 2.28%. Among them, the infection rate was the highest in Jingzhou, 7.15%; except for Wuhan City, other surveyed municipal power system workers also had different degrees of schistosomiasis infection, but the infection rates were less than 2%. Serum positive for further B-ultrasound found that schistosome liver disease 419, accounting for 54.1% of the positive number. Compared with the 2004 survey results, the prevalence of schistosomiasis infection decreased significantly. Conclusions Hubei Province power system workers schistosomiasis control effect is obvious, but still need to be strengthened.
