目的对河北省1989-1992年和2002-2004年两次人体蛔虫感染情况调查进行分析比较,掌握目前流行动态。方法按照全国人体寄生虫调查实施细则进行抽样调查,采用改良加藤厚涂片法查蛔虫卵。将两次调查的居民蛔虫感染率,分别以地区分布、经济状况、性别和年龄分组进行统计分析。结果与第1次调查相比,第2次调查人群蛔虫感染率由31.84%(20951/65803)降至1.60%(117/7316)。各组人群蛔虫感染率均显著下降,女性下降幅度高于男性;冀西丘陵片区感染率下降99.45%;不同经济收入地区,蛔虫感染率有显著性差异(x2=17.47,P<0.01),经济收入高的地区感染率最低,下降幅度最大;15岁以下年龄组感染率较高。结论河北省人群蛔虫感染率较10年前显著下降;在一些经济水平落后、卫生条件较差的地区人群蛔虫感染率仍较高,今后应加强对重点地区、重点人群蛔虫感染的防治工作。
Objective To analyze and compare the two roundworms infections in Hebei Province from 1989 to 1992 and from 2002 to 2004, and to grasp the current epidemic trends. Methods In accordance with the national human parasites survey implementation details of the sample survey, using improved Kato thick smear method roundworm eggs. The rates of roundworm infection of residents in two surveys were statistically analyzed by regional distribution, economic status, gender and age groups respectively. Results Compared with the first survey, the infection rate of Ascaris in the second survey decreased from 31.84% (20951/65803) to 1.60% (117/7316). The infection rate of Ascaris in each group was significantly lower than that of the male. The infection rate in the western Hebei hilly area was decreased by 99.45%. The infection rates of Ascaris were significantly different in different economic areas (x2 = 17.47, P <0.01) In areas with high incomes, the infection rate is the lowest, with the largest decrease; the infection rate in the age group under 15 years is higher. Conclusions The infection rate of ascaris in Hebei province is significantly lower than that of 10 years ago. In some areas where the economic level is poor and where hygienic conditions are poor, the infection rate of ascaris is still high. Prevention and treatment of roundworm infection in key areas and key populations should be strengthened in the future.
