摘要
1980～1988年对四川省18个市、地的124个县(市)282个农村调查点进行了钩虫病流行现状调查。平均感染率和克粪虫卵数分别为63.82%和563个,感染度Ⅰ、Ⅱ、Ⅲ和Ⅳ度依次占87.61%、9.21%、2.94%和0.24%;单纯十二指肠钩虫(A.d.)感染、单纯美洲钩虫(N.a.)感染和两种钩虫混合感染分别占13.05%、12.55%和70.40%,推算成虫比A.d.:N.a.为1:1.60;钩虫感染者中,平均患病率为10.84%;钩蚴皮炎发生率平均为51.31%,感染时间4～9月占98.96%,高峰期为5～7月占83.99%,主要感染场所为红薯、玉米和蔬菜地。据此认为,目前四川省钩虫病的流行仍然严重,应当引起足够的重视。
From 1980-1988, survey on epidemiological status of human hookworm infections was carried out in 124 counties of 18 cities or prefectures of Sichuan Province. The results in average value are as follows;
(1) Infection rate and EPG: 63. 82% and 563.
(2) Intensity: with grade, Ⅰ,Ⅱ,Ⅲ and IV of 87. 61%, 9. 21% 2. 94% and 0. 24%.
(3) Species infected: single infection with A. duodenale, or N.americanus or mixture infection with both were 13. 05%, 12. 55% and 74. 40%.
(4) Ratio of A. d: N. a = 1:1.60.
(5) Morbidity rate: 10. 84% among infections.
(6) Eruption rate: 51. 31%, in which 98. 96% occurred in April to September, while 83. 99% in 'peak months' May to July. The susceptible fields were those planting sweet potato, maize or vegetables.
The authors suggested that great attention shoule be paid to control program of human hookworm disease for the situation is far beyond what we expected
