Summary:To investigate the water infectivity in key water regions, and analyze the transmission risk of schistosomiasis in suspicious and high-risk environments in Hubei Province in 2016. Schistosome-endemic areas of the Yangtze River, the Hanbei River and the Fu River were chosen as the surveillance and forecast sites. The water infectivity was detected by using the sentinel mice during the flood season. The infection status of residents in the villages around the surveillance sites and the activities of human beings and domestic animals were surveyed. The emergency response system was initiated when the water infectivity areas were detected. From May to June, among the ten surveillance sites of the first batch, two positive spots with infected mice were found, accounting for 20%. All the recovered mice (totally 200) were dissected: five mice were infected, with a total infection rate of 2.5%. Totally five schistosome adult worms were collected, with mean worm burden of 1 worm per infected mouse. The site with cerca
