目的了解南平市人体肠道寄生虫病的流行状况,评价寄生虫病防治规划效果,为制定防治对策提供依据。方法以分层整群抽样法,分别于规划前的2007年和实施防治规划的2011-2014年,抽取行政村开展人体肠道寄生虫病调查,并在每个调查县内抽取幼儿园调查儿童蛲虫感染情况。结果 2007年南平市共粪检9 851人,查出寄生虫感染者896人,总感染率为9.10%,儿童蛲虫感染率18.56%(328/1 767)。2011-2014年共计粪检4 679人,查出寄生虫感染者190人,总感染率为4.06%,儿童蛲虫感染率3.87%(33/853)。实施防治规划后南平市人群肠道寄生虫感染率呈下降趋势,总感染率和钩虫感染率均随着年龄增长呈上升趋势(χ~2=49.03、53.58,P均<0.01)。结论南平市实施寄生虫病防治规划后人体肠道寄生虫感染率有所下降,但仍处较高水平,需继续加强防治工作力度。
Objective To understand the epidemic situation of human intestinal parasites in Nanping City and evaluate the effect of prevention and control of parasitic diseases so as to provide basis for the prevention and control measures. Methods The stratified cluster sampling method was used to survey the human intestinal parasites in the administrative villages in 2007 and 2014-2014 before the planning and implementation of prevention and control plans respectively. Kindergartens were also surveyed for children in each survey area. Insect infection. Results In 2007, a total of 9 851 people were seized in Nanping City. 896 were detected in the parasite, the total infection rate was 9.10%, and the infection rate in children was 18.56% (328/1 767). In 2011-2014, a total of 4 679 fecal examinations were conducted, of which 190 were found parasitic infections with a total infection rate of 4.06% and children with pinworm infection of 3.87% (33/853). The infection rate of intestinal parasites in Nanping City decreased after the implementation of prevention and control plan. The total infection rate and hookworm infection rate increased with age (χ ~ 2 = 49.03,53.58, P <0.01). Conclusion Nanping City, the implementation of parasitic disease prevention and control program of human intestinal parasitic infection rates have declined, but still at a high level, we must continue to strengthen prevention and control efforts.
