本文报道江苏省10个县99个大队血吸虫病防治的考核结果。99个大队1980年的居民粪检阳性率和有螺面积,分别较1970年下降了93.93％和98.83％;用指数曲线分析两者的年平均下降速率依次为24.43％和35.90％。1980年的居民粪检阳性率下降为1.09％,91％的大队未查到10岁以下儿童病人。钉螺的平均密度已下降为每平方市尺0.0095只,仅在2个大队发现感染性钉螺。以上结果说明在这些社、队防治血吸虫病的效果是显著的。 考核中发现尚存在着少数病情、螺情较重、流行尚未完全控制的大队。在未治病人中,晚期、夹杂症病人比例较高;残留的钉螺环境呈现“少、散、难以查出”等特点。要达到消灭血吸虫病,必须继续努力。 本文还分析了10岁以下儿童皮试、粪检在考核防治效果中的作用。
This article reports the results of the examination of schistosomiasis control in 99 units of 10 counties in Jiangsu Province. The positive rate and snail area of residents of 99 units in 1980 dropped by 93.93% and 98.83% respectively compared with that of 1970s. The annual average declining rates of the two groups were 24.43% and 35.90% respectively by means of exponential curve analysis. The positive rate of fecal examination in 1980 dropped to 1.09%, 91% of the brigade did not find the children under the age of 10 patients. The average density of Oncomelania has decreased to 0.0095 per square foot, only to find infectious snails in two brigades. The above results indicate that the effectiveness of the team in controlling schistosomiasis is significant. Examination found that there are still a small number of illnesses, spirits heavier, the prevalence has not yet fully controlled brigade. Among the non-cured patients, late patients had a higher proportion of patients with inclusion disease; residual snail environment showed “less, scattered and difficult to detect” and so on. To eradicate schistosomiasis, we must continue our efforts. This article also analyzes the children under the age of 10 skin test, fecal examination in the prevention and control of the effect of the test.
