Abstract
To investigate the epidemic of major human parasitic diseases in Chongqing City, so as to provide a reference for developing prevention and control strategies. 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. 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). 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.
