摘要
1987-1989年按不同地理位置,将广西分为东、西、南、北、中5个片区,采用分层整群随机抽样方法,对中签的20个县、市100个点51883人进行了人体寄生虫感染情况的调查,共查见人体寄生虫24种,其中线虫7种、吸虫2种、绦虫4种、原虫11种,人群寄生虫感染率为85.3%。感染人数最多的为蛔虫、鞭虫、钩虫和蛲虫,其感染率分别为66.0%、47.7%、37.8%和35.5%。据推算全区寄生虫感染者为3298.41万人,其中蛔虫、鞭虫、钩虫和蛲虫感染者分别为2550.74万、1844.44万、1463.25万和614.71万人,上述病种应列为广西优先防治的病种。人群中多种寄生虫混合感染甚为普遍,感染2种和2种以上虫种的人数占感染者的68.5%,个人感染寄生虫最多的达8种。以5—14岁儿童的感染率最高,达89.9%,女性明显高于男性,文化、卫生和经济水平较低的下等县感染率普遍高于上等县,提示儿童、妇女和贫困地区的人群,应列为防治的重点人群。
From 1987 to 1989, a survey was made on 51 883 residents in 100 sites of 20 counties and cities of Guangxi Zhuang Autonomous Region. The investigated sites, located respectively in north,south, west, east and central Guangxi, were selected according to different topography and socioeconomic status by stratified cluster sampling. The overall parasitic infection rate was 85.3%. A total of 24 species of parasites were found, including 7 species of nematodes, 2 species of trematodes, 4 species of cestodes and 11 species of protozoa. The most commonly infected parasites were Ascaris lumbricoides, Trichuris trichiura, hookworm and Enterobius vermicularis . Their infection rates were 66.0%, 47.7%, 37.8% and 35.5%,respectively. It is suggested that infections of these four parasites should be listed as major ones in control program of Guangxi. Multiparasitism was very common, 68.5% of the infected persons haboured two or more than two species of parasites. The highest record falls on a person who was infected with 8 species of parasites. The infection rate of children of 5-14 year age group was 89.9%, being the highest among different age groups. The infection rate in females was significantly higher than in males. In the counties with poor cultural , hygienic and economic conditions, the infection rates were generally higher than the well off counties. A suggestion is made that the control practice should be focused on children, women and people living in the underdeveloped areas.
