summary

Some time ago, schistosomiasis was still serious. Many people were worried about it, and they didn't know the route of transmission of schistosomiasis, so what was the route of transmission of schistosomiasis.

What is the route of transmission of schistosomiasis

First, schistosomiasis is a chronic parasitic disease caused by Schistosoma of the genus schizosoma. It is mainly prevalent in 73 countries in Asia, Africa and Latin America, with about 200 million patients. There are two main types of schistosomiasis: one is intestinal schistosomiasis, mainly caused by Schistosoma mansoni and Schistosoma japonicum; the other is urinary schistosomiasis, caused by Schistosoma egyptosum. Schistosomiasis japonica is the main epidemic disease in China.

Second, the transmission of schistosomiasis is generally due to the host eating some food containing schistosomiasis. Generally speaking, schistosomiasis may also be due to blood transmission.

Third, in every link of the transmission route, there are three important links: the water source polluted by feces containing schistosome eggs, the existence of snails and the people's contact with infected water. The way that feces pollute water is closely related to the local agricultural production mode, the living habits of residents and the feeding and management of livestock. When there are positive snails infected with Schistosoma japonicum in the water, they will become epidemic water and have infectivity to human and livestock. The ways of schistosome infection in human body can be divided into two types: production water and domestic water.

matters needing attention

At ordinary times, pay attention not to eat so much food that may contain Schistosoma, such as snails, or some other aquatic organisms.
