目的了解土源性线虫病流行动态及影响因素,为制定土源性线虫病防治策略与措施提供科学依据.方法 2006-2010年,在海南省五指山市毛阳地区每年监测人数不少于1000人；用改良加藤厚涂片法检查粪便中的土源性线虫卵,用透明胶纸肛拭法检查3～12周岁儿童蛲虫卵；采用改良饱和硝酸钠漂浮检查法检测土壤中的蛔虫卵.结果土源性线虫的总感染率从2006年的51.02％下降至2010年的27.97％,总下降率为45.18％；其中钩虫、蛔虫、鞭虫感染率从2006年的43.81％、3.88％和10.54％分别下降至2010年的25.94％、0.19％和2.03％,分别下降了40.79％、95.10％和80.74％.感染者和人群的虫卵算术均数及几何均数均逐年下降.各种虫的重度及多重感染者也逐年减少,但年长者、农民和文盲的钩虫感染率仍较高,分别为62.77％、33.24％和63.64％.儿童各年蛲虫感染的差异不大,平均感染率为39.79％.结论土源性线虫感染率呈逐年下降趋势,农民钩虫感染率仍然较高,必须采取综合性的防治措施.

Objective To observe and understand the epidemic dynamics and influence factors of soil-transmitted nematode infections,thus to predict the epidemic trend and provide scientific basis for the development of control strategies and measures.Methods During 2006-2010,the number of annual monitoring persons was not less than 1000 in the Mao Yang,Wuzhishan City.The improved Kato thick smear method was applied to detect the eggs of soil-transmitted nematodes and transparent tape anus wiping method to check ova of pinworm in 3-12 years old children.Ascaris eggs in soil were tested by modified saturated sodium nitrate floatation method.The monitoring data were statistically analyzed.Results The total rate of infection with soil-transmitted nematodes decreased from 51.02％ in 2006 to 27.97％ in 2010.The total rate of decline was 45.18％ while the infection rates of hookworm,roundworm and whipworm decreased from 43.81％,3.88％ and 10.54％ in 2006 to 25.94％,0.19％ and 2.03％ in 2010,decreased by 40.79％,95.10％,80.74％,respectively.The eggs arithmetic mean and geometric mean in infected individuals and populations were decreased year by year.Severe and multiple infection of all species of nematodes also decrease year by year.But the infection rates in elderly people,farmers and illiteracy were 62.77％,33.24％,and 63.64％respectively,still at a higher level.There was no difference in pinworm infection in children with the average infection rate 39.79％.Conclusion The soil-transmitted nematode infection rate was decreased year by year.But the infection rate of hookworm in farmers was still high,so the comprehensive prevention and control measures must be implemented.
