Schistosomiasis is a disease that poses a serious threat to our health and has been prevalent in our country for a very long time.

Predisposing factors of schistosomiasis liver disease :

Schistosomiasis is an endemic disease caused by adult schistosomes parasitizing the human body. It is mainly prevalent in 76 countries in Asia, Africa and Latin America. It is estimated that 500 to 600 million people are threatened, and as many as 200 million people suffer from the disease. The epidemic situation in our country is very serious. According to the national epidemiological survey in 1989, there are still about 1.5 million patients, including 55,000 patients in the advanced stage. The snail-infected area is 3.55 billion square meters, and there are 1.19 million sick animals. It is prone to occur in 381 counties (cities and districts) in 12 provinces, municipalities and autonomous regions, including Hunan, Hubei, Jiangxi and other provinces in the Yangtze River Basin and to its south.

Its epidemic factors include natural factors and social factors. Natural factors mainly include the natural conditions that affect the life history of schistosomes and snails, such as geographical climate, temperature, rainfall, water quality, etc.; social factors refer to the economy and living habits that affect the prevalence of schistosomiasis, especially the social system, health conditions and the national health care system, which are very important for the prevention and control of schistosomiasis. Schistosomiasis japonicum is a parasitic disease that is transmitted between humans and zoonoses. Its final hosts include humans and a variety of domestic and wild animals. Sick patients and cattle are the main sources of infection. Water sources are mainly contaminated by feces containing schistosome eggs. The presence of snails and human contact with infected water are three important links. Humans are susceptible to schistosomiasis.
