| Abstract: |
| 河南省长葛农村经饮水改良和粪便无害化处理后使腹泻病得到控制。试验村1983年腹泻发病率为48%,1986年建起简易集中式供水系统后发病率降至28.2%;改水后再加上修建双瓮漏斗型厕所,使腹泻发病率降至11.08%,较1983年下降76.92势。单纯改水使4岁以下儿童发病减少3/4;改水和改厕可使各年龄组发病率降低54%~79%,对降低6~10月腹泻发病高峰效果显著,但病原分布无明显差异。该两项措施人均投资46.31元,一年内由疾病减少、节省挑水劳力和积肥可获23.53元效益,效益与费用比值(BCR)为0.51。预计总投资可在2年内自身偿还,第三年及以后的BCR为4.42。 |
