目的了解岱山县农村居民土源性寄生虫病感染现状,为采取针对性防控措施降低感染率提供依据。方法采用多阶段随机抽样方法,抽取3个行政村,每个村再随机抽取260名>1周岁常住居民进行调查,采用改良加藤厚涂片法检测蛔虫、钩虫、鞭虫;3~6岁儿童除粪便检测外,同时用透明胶纸检测蛲虫卵。结果共检测当地773名居民的粪便样本,检出寄生虫卵阳性10例,阳性率1.29%;男性居民阳性率1.64%,女性居民阳性率1.07%;1岁~组居民阳性率0.60%;60岁以上居民阳性率1.82%,不同性别和年龄居民虫卵阳性率比较差异无统计学意义(P>0.05);山礁村粪检阳性率2.73%,明显高于金家村的0.78%和山外村的0.38%(P<0.05)。结论岱山县农村居民土源性寄生虫卵阳性率较以往明显下降,但不同村之间还存在地区差异,今后应重点关注感染率较高、经济相对落后的村。
Objective To understand the current situation of indigenous parasitic diseases in rural residents in Daishan County, and to provide basis for taking targeted prevention and control measures to reduce the infection rate. Methods A total of 260 administrative villages> 1-year-old residents were randomly selected from each of the 3 administrative villages using a multi-stage random sampling method to investigate. Roundworm, hookworm and whipworm were tested by modified Kato thick smear method. Children aged 3 to 6 years In addition to fecal testing, at the same time with a transparent tape test oyster eggs. Results A total of 773 local residents were tested for stool samples. 10 cases were positive for parasite eggs and the positive rate was 1.29%. The positive rate was 1.64% for male residents and 1.07% for female residents. The positive rate was 0.60% for residents aged 1 to 60 years. The positive rate of residents aged above one year was 1.82%. There was no significant difference in the positive rate of insect eggs between residents of different sexes and ages (P> 0.05). The positive rate of fecal examination in mountain reef was 2.73%, significantly higher than that of Jinjiacun 0.78% 0.38% of villages (P <0.05). Conclusion The positive rates of soil-borne parasite eggs of rural residents in Daishan County decreased significantly compared with the past years. However, there are still some regional differences among different villages. In the future, we should focus on villages with relatively high infection rates and relatively backward economy.
