南平市实施寄生虫病防治规划后肠道寄生虫病控制效果分析

Effect of control program of human intestinal parasitic diseases in Nanping City

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 status of human intestinal parasitic diseases and evaluate the effect of the control program in Nanping City,so as to provide an evidence for improving the disease control.Methods The villages were selected by the stratified cluster sampling method and the residents in these villages were surveyed for human intestinal parasitic diseases,and kindergartens were also selected and the children in these kindergartens were surveyed for Enterobius vermicularis infection.Results In 2007,before the control program,9 851 residents of Nanping City were surveyed,with the parasitic infection rate of 9.10%（896 infection cases）,and the infection rate of E.vermicularis of children was 18.56%（328/1 767）.From 2011 to 2014,when the control program was performed,4 679 residents were surveyed,with the infection rate of 4.06%（190 infection cases）,and the infection rate of E.vermicularis of children was 3.87%（33/853）.After the control program was launched,the infection rates of human intestinal parasites were decreased.The overall parasitic infection rate and hookworm infection rate showed increasing trends by age（ χ^2= 49.03 and 53.58 respectively,both P〈0.01）.Conclusion The infection situation of human intestinal parasites is decreased after the implementation of the control program but the infection rate is still at a high level,and the control work should be strengthened.
