Schistosomiasis is a public health burden in developing and resource-poor regions of the world, especially in agricultural and rural areas. Worldwide, schistosomiasis has a tremendous health burden, with an estimated 251 million people treated in 2021 alone.1 Schistosomiasis is caused by trematode worms (blood flukes), which penetrate the skin of their host in contaminated freshwater. Symptoms can include abdominal pain, diarrhoea, haematochezia and haematuria. Schistosomiasis was once endemic in Japan, but after an extensive and effective eradication programme aimed primarily at the intermediate host—(Oncomelania, a freshwater snail), no locally acquired cases have been reported in Japan since 1977.2
