目的了解广东省人体重要寄生虫感染现状及防治效果。方法按照2001年全国统一制定的调查方案,于2002～2003年在全省范围内按地区分层整群随机抽样的方法进行调查。以Kato-Katz法检查肠道蠕虫卵,透明胶纸肛拭法检查12岁以下儿童蛲虫卵。结果土源性线虫和华支睾吸虫感染共抽样调查17县个(市、区)51个点(村)26 363人,寄生虫总感染率为28.59%。其中男性感染率为29.99%、女性为27.20%;年龄组感染率5～9岁组最高,为37.36%,15～19岁组最低,为19.56%;渔民感染率最高,为44.00%,待业人员最低,为8.70%。人群蛔虫、钩虫、鞭虫、蛲虫和华支睾吸虫感染率分别为7.78%、6.13%、4.58%、30.38%和10.13%,其中钩虫感染率女性高于男性,蛲虫、华支睾吸虫感染率男性高于女性(P均<0.01)。结论广东省肠道寄生虫感染率总体呈下降趋势,但华支睾吸虫、蛲虫感染率上升。
Objective To understand the status quo and prevention and treatment of important parasitic infections in Guangdong Province. Methods According to the survey plan formulated in 2001 by a unified nationwide survey, random sampling was conducted in different regions of the whole country from 2002 to 2003 according to the random sampling method. The Kato-Katz method was used to examine gut worm eggs and translucent tape anal swabs to examine the eggs of children under 12 years of age. Results A total of 26 363 51 villages (villages) in 17 counties (cities and districts) were sampled by sampling. The total infection rate of parasites was 28.59%. Among them, the rate of male infection was 29.99% and that of females was 27.20%. The infection rate of age group was the highest at 5-9 years old (37.36%), the lowest was 15.5 years old (19.56%), the infection rate of fishermen was the highest (44.00%), The lowest is 8.70%. The prevalence of hookworm, hookworm, whipworm, pinworm and Clonorchis sinensis was 7.78%, 6.13%, 4.58%, 30.38% and 10.13%, respectively. The prevalence of hookworm infection in female was higher than that of male, pinworm and Clonorchis sinensis The infection rate was higher in males than females (all P <0.01). Conclusions The intestinal parasitic infection rate in Guangdong Province generally shows a decreasing trend, but the infection rate of Clonorchis sinensis and pinworm increased.
