Abstract: Objective To investigate the epidemic of major human parasitic diseases in Chongqing City, so as to provide a reference for developing prevention and control strategies. Methods According to the unified methods formulated by the national investigation scheme and stratified cluster random sampling, 36 rural pilots and 50 urban pilots were selected in Chongqing City. The number of the objects investigated in individual pilot was defined over 250. Results Totally 22 263 residents were detected. The overall infection rate of intestinal parasites was 5.41%. The infection rates of Ascaris lumbricoides, hookworm, Trichuris trichiura, and Enterobius vermicularis were 1.20%, 4.23%, 0.13% and 0.47% respectively. Only 0.22% of the infections were co?infections. The infection rate of overall intestinal parasites was statistically higher in the females than that in the males ([χ2] = 15.19, P < 0.05), and the infection rates were significantly different among various age groups, occupations, education levels, and regions ([χ2] = 15.19, 396.72, 421.07, 347.79, all P < 0.05). Conclusions The infection rates of major human parasites in Chongqing show an obviously decreasing tendency compared with the rates of the past twice of national surveys. In the future, the controlling practices are obliged to focus on reducing the infection rates of soil?borne parasites.

摘要: 目的 了解重庆市人体重点寄生虫病流行现状,为制定防治策略提供科学依据。 方法 按照分层整群抽样的原则,抽取重庆市36个农村调查点和50个城镇调查点开展调查。每个调查点调查不少于250人。 结果 共调查22 263人,寄生虫总感染率为5.41%。蛔虫、钩虫、鞭虫和蛲虫的感染率分别为1.20%、4.23%、0.13%和0.47%。混合感染占0.22%。不同性别、年龄、职业、文化程度及地区间寄生虫感染率的差异具有统计学意义([χ2] = 15.19、396.72、421.07、347.79,P 均< 0.05)。结论 重庆市人群寄生虫感染率呈明显下降趋势,土源性线虫病仍是今后寄生虫病防治工作的重点。 [关键词]
