目的掌握山东省人体肠道蠕虫感染流行现状及全民服药驱虫效果,为采取相应措施提供依据。方法以整群抽样方法对34 384名山东农村居民采用改良加藤厚涂片法(Kato-Katz)和透明胶纸肛拭法检查肠道蠕虫感染情况,在感染率≥20%的重点县市,以阿苯达唑全民服药法控制土源性线虫感染并考核其疗效。结果调查农村居民34 384人,肠道蠕虫总感染率为3.51%,其中蛔虫感染率为0.49%,钩虫为0.1%,鞭虫为2.57%,蛲虫为3.27%,华支睾吸虫为0.01%;农村居民全民化疗人群141.19万,土源性线虫感染率较化疗前大幅下降。结论山东省肠道蠕虫的虫种、感染率、感染度、多虫种感染现象均有大幅下降;阿苯达唑全民化疗降低农村居民土源性线虫感染率效果显著。
Objective To understand the prevalence of human intestinal helminth infection in Shandong Province and the effect of detoxification by all the people in order to provide the basis for taking corresponding measures. Methods A total of 34 384 rural residents in Shandong were tested for intestinal helminth infection by using Kato-Katz and transvaginal anal swabs in a cluster sampling method. In key counties and cities where the infection rate was ≥20% Albendazole people taking medicine to control soil-borne nematode infection and assess its efficacy. Results A total of 34 384 rural residents were surveyed. The total infection rate of intestinal worms was 3.51%. The infection rate of roundworm was 0.49%, hookworm was 0.1%, whipworm was 2.57%, pinworm was 3.27%, Clonorchis sinensis was 0.01% ; The population of rural residents was 1.1419 million, and the infection rate of soil-borne nematodes dropped significantly compared with that before chemotherapy. Conclusion The incidence of infection, infection and multi-infestation of intestinal worms in Shandong Province all dropped significantly. Albendazole chemotherapy was effective in reducing the infection rate of indigenous nematodes in rural residents.
