Understand the infection process of Schistosoma japonicum and talk about how to prevent Schistosoma japonicum.

The adult Schistosoma japonicum in patients or sick cows lays eggs, which are discharged with feces, and the feces come into contact with water sources, hatching out miracidium. The miracidium infects Oncomelania, which is divided into two parts in Oncomelania, producing a large number of cercaria, which overflows from Oncomelania and distributes in the wild water environment. People are infected with schistosomiasis when they come into contact with infected water.

From the point of view of ordinary people, the only effective way to prevent schistosomiasis is not to touch suspicious waters.

From a professional point of view, to prevent schistosomiasis, it is necessary to treat sick cattle in time, control water pipe dung, kill snails, educate and publicize, and eliminate farm cattle.
