摘要
在采取连续的综合防治措施下，使肠线虫病感染程度降至低水平后，如何继续开展防治工作，以期不断巩固和取得更大成效。本文总结连续４年（１９９２～１９９５年）的防治探索的主要成绩：（１）每年１次选择性化疗（吉吴村）使肠线虫感染率从８．７６％降为２．４５％。其中蛔虫、钩虫和鞭虫的感染率分别为４．４３％～０．３９％、２．６０％～１．１６％及２．１２％～１．０３％；感染度（ＥＰＧ）分别为２３７．６０～１．２０、１．６０～０．２４及０．６９～０．４１。随着感染程度的不断下降，化疗的即时疗效逐年提高，阴转率为８０．９０％（１９９１）、９６．４３％（１９９２）、９７．５０％（１９９３）和９７．８７％（１９９４）；（２）每３年１次集体化疗，连续２次，６年间当地居民感染率（汉南村）逐渐下降：７６．０１％（１９８９）、４６．５６％（１９９２）及１４．４２％（１９９５）；（３）持续开展健康教育作为综合防治的重要措施，起到加速和巩固防治成效的促进作用。与单纯集体化疗的汉南村同步相比，居民感染率（墩头村）逐步下降更明显：７５．４３％（１９８９）、３６．５９％（１９９２）和１２．３１％（１９９５）；（４）粪管改厕在宋家村进行，集体化疗２年后?
This paper presents the main experiments of 4 years continuous control research for intestinal nematodiasis in the villages with low prevalence of infection. The results are summarized as follows : (1)A continued selective chemotherapy once a year was conducted for 4 years in Jiwu village. The prevalence of intestinal nematodiasis reduced from 8.76%(1992) to 2.45%(1995), in which the infective rates of ascariasis, hookworm infection and trichuriasis were from 4.43% to 0.39 %, 2.59% to 1.16% and 2.12% to 1.03%, and the intensities of infection(eggs per gram, EPG) were from 237.60 to 1.20, 1. 60 to 0. 24 and 0.69 to 0.41 respectively. However, the cure rates after treatment increased year after year i.e. 80.90%(1991), 96.43%(1992), 97.50%(1993), 97.87%(1994);(2)The mass chemotherapy was conducted once in every 3 years in Hannan village. At the end of second time, the infective rates of intestinal nematodiasis decreased apparently from 76. 01% in 1989 to 46.56%(1992) and then to 14.42%( 1995) ; ( 3) Health education combined with mass chemotherapy was conducted in Dengtou village with more effective and rapid results obtained(75.43% in 1989, 36.59% in 1992 and 12.31% in 1995) than that of Hannan village( mass chemotherapy only); (4) Reformation of lavatories was conducted in part of families in Songjia village. 2 years after mass treatment, the infective rates of intestinal nematodiasis in the families with the reformed lavatories(12.9%) were slightly lower than those of the families with non reformed lavatories(15.04%).
