摘要： 目的  了解淮安市淮安区肠道线虫病流行态势，为科学制定防治策略和措施提供依据。 方法  每年选择1个镇1个村，调查2岁以上常住居民1 000人，其中14岁以下儿童≤1/3。采用改良加藤厚涂片法（Kato-Katz法）1送2检查肠道线虫卵，统计人群总感染率、单虫感染率和感染度。 结果  2011~2015年共监测5 104人，肠道线虫感染率在0.10%~0.95%之间，平均感染率为0.61%。钩虫感染占感染虫种的58.06%，各虫种平均感染率差异有统计学意义（χ2＝8.99，P＜0.05）。蛔虫、钩虫、鞭虫平均感染度分别为1 944.00、247.11和576.00，均未发现重度感染者和多重感染。感染率从2011年的0.79%下降到2015年的0.10%，下降了87.34%。各年度间总感染率差异有统计学意义（χ2＝9.65，P＜0.05），单虫感染率差异均无统计学意义（χ2蛔＝1.84，P＞0.05；χ2钩＝6.79，P＞0.05；χ2鞭＝3.85，P＞0.05）。除20~岁年龄组外，其余各年龄组均有感染，50~以上年龄组占感染总数的70.97%。男性感染率为0.44%，女性感染率为0.75%，两者间差异无统计学意义（χ2＝2.05，P＞0.05）。除干部外，其余职业人群均有肠道线虫感染，各职业间总感染率差异无统计学意义（χ2＝0.65，P＞0.05）。 结论  淮安市淮安区肠道线虫感染率逐年下降且呈低流行状态，需继续做好中老农民等重点人群的防控工作。

Abstract:

Objective  To investigate the epidemic trend of intestinal nematodiasis in Huai'an district of Huai’an city for evidences to plan scientific preventive and control measures for this infection. Methods The survey was yearly conducted in a population of 1000 aged over 2 years, randomly selected from a village under an administrative township. Children under 14 years of age accounted for ≤1/3 in the subjects surveyed. Modified Kato-Katz method was used to detect the eggs of intestinal nematode, and the total infection rate, single worm infection rate and infection degree were calculated. Results A total of 5104 subjects were surveyed from 2011 through 2015. Intestinal nematode infection ranged from 0.10% to 0.95%(average 0.61%), and hookworm infection accounted for 58.06% of the infected species. The difference was significant regarding the average infection rate by individual species (χ2＝8.99, P＜0.05).Mean infection degree was 1 944.00, 247.11 and 576.00 for roundworm, hookworm and whipworm, respectively. Severe infection and multiple infection were free. The infection rate was decreased by 87.34% from 0.79% in 2011 to 0.10% in 2015, and was significant between years(χ2＝9.65, P＜0.05), yet the single worm infection rate remained no difference (χr2＝1.84, P＞0.05. χh2＝6.79, P＞0.05. χw2＝3.85, P＞0.05). Infection was seen in different age groups except for subjects aged 20 years. Those aged over 50 years accounted for 70.97% of the total infected population. The infection rate was not statistically different between males and females( 0.44% vs. 0.75%; χ2＝2.05, P＞0.05). Infection with intestinal nematodes occurred in population with different occupations except for cadres, yet the difference was not significant between occupations (χ2＝0.65, P＞0.05). Conclusion Intestinal nematode infection tends to drop year by year in population in Huai'an district, and following prevention and control of the infection should target at the middle aged and the elderly farmers.
