ABSTRACT
Schistosomiasis japonica is a major public health problem in China. Domestic animals play a major role in the transmission of Schistosoma japonicum to humans. To better understand the epidemiology of schistosomiasis japonica in domestic animals in the mountainous areas of China, we performed a 5-year longitudinal study of schistosomiasis in cattle and horses in Yunnan Province from 2009 to 2013. We also performed a concurrent drug-based intervention study in three settlement groups in Yunnan Province aimed at developing an effective means of controlling transmission in this region. The prevalence of infection in cattle fluctuated between 1.67% and 3.05% from 2009 to 2011, and monthly treatments of schistosome-positive animals reduced the prevalence to 0% (P<0.05) from 2012 to 2013. Prior to the intervention, we found that schistosomiasis was prevalent from May to October, with the highest prevalence observed in June (10.00%). We surveyed for environmental schistosome contamination, and 94.29% of the miracidia found were from cattle. Our study showed that it is possible to eliminate schistosomiasis in domestic animals in the mountainous regions of China by monthly treating cattle and horses from schistosome-positive households from May to October.
