2007—2011年淮安市肠道寄生虫病纵向监测结果

Longitudinal surveillance of intestinal parasites in Huai'an City from 2007-2011

目的为及时了淮安市钩虫、蛔虫、鞭虫等肠道寄生虫病流行动态和影响因素,掌握流行规律,预测流行趋势,为制定防治策略和评价措施提供科学依据。方法选择淮安市涟水县河网乡谭陈村,连续5年运用改良加藤厚涂片法(Kato-Katz),监测人群的肠道寄生虫病感染情况。感染者每年2次运用甲苯咪唑进行驱虫治疗。结果 2007年调查1 062人,查出钩虫、蛔虫、鞭虫、蛲虫和姜片虫感染者33人,总感染率为3.11%;2008年调查1 001人,查出钩虫、蛔虫和鞭虫感染者27人,总感染率为2.70%;2009年调查1 219人,查出钩虫、蛔虫和鞭虫感染者6人,总感染率为0.49%;2010年调查1 116人,查出钩虫、蛔虫和鞭虫感染者17人,总感染率为1.52%;2011年调查1 029人,查出钩虫、蛔虫和鞭虫感染者10人,总感染率为0.97%。感染率在5年内下降了68.81%,男女感染率相比差异有统计学意义(χ2=4.50,P<0.05)。肠道寄生虫感染者主要集中在50～59岁年龄组,其感染病例数占总感染病例数的38.33%(23/60),明显高于其他年龄组。结论该监测点连续5年肠道寄生虫总感染率波动在5%以下,但随着感染者的治愈不断有新感染者出现,为巩固防治成果,在今后应以加强重点人群监测和相关健康知识的宣传工作为重点。

[Objective]To understand the epdemic dynamics and influencing factors of hookworm,roundworm,whipworm,and other intestinal parasites in Huaian City,to master the epidemic rule,to predict epidemic trends,and provide scientific evidence for developing control strategies and evaluation measures.[Methods]The Tanchen village was chosen to monitor the epidemic of intestinal parasites infection for 5 consecutive years by using the Kato-Katz thick smear method（Kato-Katz）.Infected victims were treated with mebendazole twice a year.[Results] In 2007,1 062 people were surveyed,of whom 33 were identified with hookworm,roundworm,whipworm,pinworm,and ginger insects infections,the overall infection rate was 3.11%.In 2008 it surveyed 1 001 people,of whom 27 were identified with hookworm,roundworm and whipworm infections,the overall infection rate was 2.70%.In 2009 it surveyed 1219 people,of whom 6 were identified with hookworm,roundworm and whipworm infections,the overall infection rate was 0.49%.In 2010 it surveyed 1 116 people,of whom 17 were identified with hookworm,roundworm and whipworm infections,the overall infection rate was 1.52%.In 2011 it surveyed 1 029 people,of whom 10 were identified with hookworm,roundworm and whipworm infections,the overall infection rate was 0.97%.The infection rate decreased by 68.81% in 5 years,and there was significant difference between male and female（χ2=4.50,P0.05）.Intestinal parasitic infections mainly concentrated in the age group of 50-59 years,its infection number occupied 38.33%（23/60） of the total number of cases infection,which was significantly higher than the other age groups.[Conclusion]Intestinal parasites infection rate fluctuates under 5% in monitoring points of 5 consecutive years,but there are new infections along with the healing of infected persons,it is important to strengthen population monitoring and propaganda health-related knowledge in order to consolidate the results of control.
