| Abstract: |
| 本文报告经调查证实江苏省存在着不少有钉螺而无血吸虫病流行（有螺无病）地方，共468个大队，分布于9个县的112个公社。这些大队中，属平原型的429个，属山丘型的39个。对这两型有螺无病地方，各取3个大队作流行病学调查研究的结果，说明这6个大队的有螺无病现象已存在23年以上，那里有螺无病存在的主要原因是没有足够数量的传染源输入。本文还就调查研究结果，对血防工作上有关问题作了探讨。 |

| This paper describes the geographical distribution of 468 brigades of 112 communes in 9 counties with local Oncomelania snail infestation without aboriginal human schistosomiosis in Jiangsu Province. Among the brigades, 429 are of the "Plain region" type and 39 of the "hiliy region" type.Three brigades from each type were chosen for epidemiological study, and it was found that all 6 brigades, although still infestated with local Oncomelania snail,had been free from human schistosomiasis for more than 23 years.The interruption of transmission might be due to the absence or low frequency ova-bearing feces in the local residents and animals.The significance of these findings concerning schistosomiasis control is discussed. |
