I want to travel to Xianning. What preparatory measures should be taken to prevent and control schistosomiasis? Is schistosomiasis serious in Yindong and Yaochi Hot Springs?

I am from Xianning, and I have never heard of schistosomiasis. Schistosoma only exists in water, so you can learn about Schistosoma. The hidden water cave is in Tongshan, and there is a river in it. It's a little cold now, so I guess you won't go into the water either. Yaochi Hot Spring is a place to soak in hot springs. Will there be schistosomiasis in hot spring water?
