![]() Japonicum infection in both humans and the intermediate host snails and reduced the infection risk by 3–4 times relative to the conventional strategy. A 2018 review found that the 'new integrated strategy' was highly effective to reducing the rate of S. The morbidity control strategy focused on synchronous chemotherapy for humans and bovines and the new strategy developed in 2004 intervenes in the transmission pathway of schistosomiasis, mainly including replacement of bovines with machines, prohibition of grazing cattle in the grasslands, improving sanitation, installation of fecal-matter containers on boats, drug therapy, snail control, and health education. Integrated strategy in China In, the national strategy for schistosomiasis japonica control has shifted three times since it was first initiated: transmission control strategy (from mid-1950s to early 1980s), morbidity control strategy (from mid-1980s to 2003), and the 'new integrated strategy' (2004 to present). Schistosoma mekongi is found in Southeast Asia. ![]() ![]() Schistosoma japonicum is found throughout Asia. 187 Schistosoma mansoni is found in the Caribbean, South America, the Middle East, and Africa. Further, at the 1986 on the, restoring prawns upstream of the dam reduced both snail density and the human schistosomiasis reinfection rate. Schistosoma are trematodes whose complex life cycles require an intermediate freshwater snail host they infect approximately 200 million people worldwide. After the construction of fourteen large dams, greater increases in schistosomiasis occurred in the historical habitats of native prawns than in other areas.
