2012-2015年合肥市人群土源性线虫病监测结果分析

目的 分析2012-2015年合肥市土源性线虫病监测结果，为制定合肥市“十三五”寄生虫病防治策略提供依据。方法 每年对长丰县、巢湖市、庐江县监测点采用Kato?Katz法检查监测人群的蛔虫、鞭虫、钩虫感染情况，采用透明胶纸法检查6岁以下儿童蛲虫感染情况。结果 2012-2015年全市共调查12 496人，感染者84人，其中钩虫感染人数最多（70例），蛔虫最少（3例）。2014年人群感染率高于其他年份，差异有统计学意义（P < 0.008）；6岁以上各年龄组感染率差异有统计学意义（[χ2] = 27.229，P < 0.05），66岁以上年龄组感染率高于其他年龄组；女性感染率高于男性，差异有统计学意义（[χ2] = 5.378，P < 0.05）；长丰县监测点感染率高于其他监测点，差异有统计学意义（P < 0.017）。结论 2012-2015年合肥市人群土源性线虫病感染率低于5%，处于较低水平。钩虫感染人数最多，今后钩虫是该市重点防治的寄生虫。

Surveillance of soil-borne nematodiasis in population in Hefei City, 2012-2015

Objective To analyze the surveillance results of soil?borne nematodiasis in Hefei City from 2012 to 2015， so as to provide the evidence formulating the Hefei “Thirteen?five” parasitic disease prevention strategy. Methods The population in monitoring points in Changfeng County， Lujiang City and Chaohu County were investigated for Ascaris lumbricoides， Trichuris trichiura and hookworm infections with Kato?Katz technique every year from 2012 to 2015， and the children aged less than 6 years were checked for Enterobius vermicularis infection by using the cellophane tape method. Results A total of 12 496 people were investigated from 2012 to 2015， the number of infections was 84， and among them， the number of hookworm infection was the most （70 cases） and the number of A. lumbricoides was the least （3 cases）. The infection rate in 2014 was higher than that in other years， and there was a statistically significant difference （P < 0.008）. There was a statistically significant difference among all age groups over 6 years of age in the infection rates （[χ2] = 27.229， P < 0.05）， and the infection rate of the age group over 66 years was higher than that of the other age groups. The infection rate in the female was higher than that in the male （[χ2] = 5.378， P < 0.05）. The infection rate in the monitoring point in Changfeng County was higher than that in the other monitoring points （P < 0.017）. Conclusions From 2012 to 2015， the infection rate of soil?borne nematode infections is lower than 5% in Hefei City. The number of hookworm infection is the most. Therefore， during the "Thirteen five" period， the key point of prevention of parasitic infections is hookworm infection.
