目的掌握土源性线虫病在海南省的流行动态及流行规律,为制定土源性线虫病防治策略与措施提供科学依据。方法根据流行区地理位置选择两个调查点,采用一粪三检的改良加藤厚涂片法(Kato-Katz法),检查土源性线虫卵;对3～12岁儿童加做透明胶纸肛拭法检查蛲虫卵。使用EpiData2.1a软件建立调查资料数据库,应用Excel和Spss10.0软件,对监测资料进行统计学分析。结果全省监测2028人,总感染率为39.23%,其中钩虫、蛔虫、鞭虫及3～12岁儿童蛲虫感染率分别为32.35%、0.69%、3.80%、37.05%。流行特征以丘陵地区感染高于山区,以汉族、农民、文盲的感染最高,女性感染高于男性。总感染率及钩虫感染率均随着年龄的增加而升高;鞭虫和蛔虫感染分别以学生和学龄前儿童较多。结论海南省中部及中北部地区土源性线虫感染呈下降趋势,但年长农民钩虫和3～12岁儿童蛲虫感染仍很严重,应作为优先防治重点,并采取综合性的防治措施,以达到控制土源性线虫病目标。
Objective To understand the epidemiological and epidemic patterns of soil-borne nematodes in Hainan Province and provide scientific evidence for the development of strategies and measures for controlling soil-borne nematode diseases. Methods According to the geographical location of the endemic area, two investigation points were selected, and a modified method of Kato-Katz test was used to check the soil-borne nematode eggs. Three to 12-year-old children were applied with transparent adhesive tape Anal swab method check the worm eggs. The EpiData2.1a software was used to establish the survey data database. The data of the monitoring data were statistically analyzed by Excel and Spss10.0 software. Results The total number of surveillance was 2028, with a total infection rate of 39.23%. The infection rates of hookworm, roundworm, whipworm and children aged 3 ~ 12 years were 32.35%, 0.69%, 3.80% and 37.05%, respectively. The epidemic characteristics of infection in hilly areas than in mountainous areas, Han, peasants, illiteracy, infection, women infected than men. Total infection rate and hookworm infection rate increased with age; whipworm and roundworm infections were more students and preschool children. Conclusion The infection of soil-borne nematodes in central and northern central part of Hainan Province is on the decline. However, the prevalence of pinworm infection in older peasant hookworms and children aged 3 ~ 12 years is still serious, and should be taken as priority prevention and control measures and taken comprehensive prevention and treatment measures To control the target of soil-borne nematodes.
