目的掌握巍山县血吸虫病疫情,为制定防治措施提供科学依据。方法人群病情采用间接血凝法(IHA)、粪便集卵孵化和Kato-Katz法检查;家畜病情采用粪便顶管孵化检测;螺情采用系统抽样法和环境抽样法检查。结果人群免疫学阳性率、人群粪便孵化阳性率、人群Kato-Katz阳性率、人群感染率、家畜病情阳性率分别为8.94%、1.56%、0.00%、0.12%、0.00%;IHA查病以6~岁组最高(12.00%),60~岁组最低;女性阳性率为10.37%,男性阳性率为7.48%;共查出有螺面积130 114 m2,有螺框出现率4.22%,活螺平均密度0.145只/框,未发现阳性螺,人群感染率和家畜阳性率比2007年明显下降,有螺面积略有减少,钉螺密度上升。结论 2008年巍山县的钉螺面积、人群病情、家畜病情等血吸虫病各项指标均下降,药物灭螺、人畜同步化疗、牲畜圈养、禁牧、健康教育、改厕等综合性措施是有效的。
Objective To grasp the epidemic situation of schistosomiasis in Weishan County and provide a scientific basis for making prevention and control measures. Methods The condition of the population was detected by indirect hemagglutination (IHA), egg hatching by stool and Kato-Katz method. The feces was tested by hatching of the feces pipette. The system was sampled by systematic sampling and environmental sampling. Results The positive rate of immunocompetence, the positive rate of hatch in crowd, the positive rate of Kato-Katz in population, the infection rate of population and the positive rate of domestic animal were 8.94%, 1.56%, 0.00%, 0.12% and 0.00% The highest positive rate was 12.00% in group A and the lowest was in group 60-60. The positive rate was 10.37% in female and 7.48% in male. A total area of 130 114 m2 was found and the occurrence rate of screw frame was 4.22% Density 0.145 / box, no positive snails, the population infection rate and the positive rate of livestock than in 2007 decreased significantly, there is a slight decrease in snail area, snail density increased. Conclusion In 2008, all the indexes of schistosomiasis area such as snail area, population condition and domestic animal condition in Weishan County were decreased. Comprehensive measures such as drug snail killing, syncytial therapy of human and animals, livestock captivity, grazing prohibition, health education and restroom were effective .
