A Survey on Intestinal Parasites Infestation Status in Lianyuna City

目的 了解涟源市人体肠道寄生虫感染现状。 方法 采用随机抽样方法确定3个乡(镇)做为调查点,改良加藤厚涂片法检查计算感染率。 结果 本次调查3个乡(村) 5 2 5户15 47人共发现有6种寄生虫感染,总感染率和单虫种感染率均有年龄、性别、职业和地域差别,且有统计学意义(P <0 .0 1)。寄生虫总感染率为2 8.83 % ,虫种中蛔虫感染率占首位(2 1.85 % ) ,值得一提的是在老疫区(伏口镇)没有查到华支睾吸虫,而在做为对照区的杨市镇却查出8例,且对照区的感染率(65 .5 7% )明显高于老疫区(3 1.95 % ) ;人群中以女性农民的感染率最高(3 3 .92 % ) ,农民和学生是主要的感染群体,年龄组以5 0岁组(3 9.61% )和5岁组(3 6.17% )为甚,男性(2 5 .46% )低于女性(3 2 .0 7% )。 结论 该市肠道寄生虫感染状况严重,感染率高且既往本底不清。

Objective To survey the infestation status of intestinal parasites in Lianyuan city district. Methods Three countrysides were selected as investigation points by the case-control method. Its infection rate was calculated from the Kato-Katz feces smear. Results One thousand five hundred and forty-seven people of 525 families in three villages were investigated and six intestinal parasites were found. The age, sex, occupation and regional significant differences were existed in total-and single-parasite infection (P<0.01). The results indicated that the total infection rate was 28.83%, of which the rate of ascarid infection was in the first place(21.85%). It is noticeable that eight clonorchiasis cases were found in the control group but none in the original epidemic region Fukou Town. Moreover, the infection rate of the former was higher sharply than that of the latter. The infection rate of female farmers in the population was the highest (33.92%). Farmers and students were the major group of infestation, and the 50-year and 5-year groups had highest infestation rate. The infection rate of males was lower than that of females. Conclusion The infestation status of intestinal parasites in Lianyuan city district is severe as the prevalence is high and the basic data are unclear. It is urgent that investigation and control on intestinal parasitism should be strengthened.
