An investigation of family distribution patterns of schistosomiasis japonica was carried out in four pilot villages in Yunnan Province. Family clustering of the disease was present in Bihuayuan Village before and after economic reform (site A); however, such clustering did not occur in Tuanshan and Liantie Villages (sites B and C) in the same periods. Being contrary to the stage prior to economic reform family clustering existed in Zhonghe Village (site D) after the reform. The results obtained from single- and multifactor analysis showed that the main human behavior related to family distribution of schistosomiasis in mountainous regions of Yunnan Province included the frequency of laborer migration, contact with cercariae-infested water in public places or family microenvironments with a high transmission potential, promiscuous defecation and status of cattle grazing. The frequency of laborer migration and human contact with cercariae-infested water in public places in sites B and C without family clustering was higher than that in sites A and D with family clustering. Place for promiscuous defecation and cattle grazing in site A converged compared with that in sites B and C.
在云南省的四个试点村庄开展了日本血吸虫病家庭分布模式的调查。经济改革前后，碧花园村（A点）均存在该病的家庭聚集现象；然而，同期团山村和炼铁村（B点和C点）未出现此类聚集。与经济改革前阶段相反，中和村（D点）在改革后存在家庭聚集。单因素和多因素分析结果表明，云南省山区与血吸虫病家庭分布相关的主要人类行为包括劳动力迁移频率、在具有高传播潜力的公共场所或家庭微环境中接触感染尾蚴的水、随地大便以及放牛状况。无家庭聚集的B点和C点劳动力迁移频率和人类在公共场所接触感染尾蚴的水的情况高于有家庭聚集的A点和D点。与B点和C点相比，A点随地大便和放牛的地点较为集中。
