How to prevent schistosomiasis?

summary

Let's not underestimate schistosomiasis. It is a widespread disease, especially in Asia and Africa. Therefore, schistosomiasis is a typical endemic disease. Let's introduce the prevention methods of schistosomiasis, which can reduce the incidence of schistosomiasis.

How to prevent schistosomiasis?

Management of source of infection: general survey of patients and sick cattle in epidemic areas every year to ensure no missed diagnosis. General chronic patients can be treated with single dose praziquantel therapy, which can significantly reduce the infection rate. 5 mg / kg for buffalo and 2 mg / kg for cattle. The cure rate was over 98%.

Snail control is the key to prevent the disease. We should find out the snail situation, adjust measures to local conditions, adopt physical snail control or drug snail control method, insist on repeated. It can be combined with the construction of water conservancy and the transformation of snail breeding environment, according to local conditions, choose cultivation, breeding, flooding, soil burial and fire methods. The commonly used molluscicidal drugs are sodium pentachlorophenol and niclosamide. Sodium pentachlorophenol can kill adult snails, juveniles and eggs, but it is also toxic to crops, fish and human; Niclosamide is only toxic to fish. It has high molluscicidal efficiency, long lasting effect and slow action. The combination of niclosamide and sodium pentachlorophenol can improve the efficacy.

Protection of vulnerable groups: try to avoid contact with epidemic water, especially children should be strictly prohibited from swimming, bathing, playing in water, catching fish and shrimp in epidemic water. If you have to contact with epidemic water due to work needs, you should strengthen personal protection, such as dipping clothes with 1% niclosamide alkaline solution to prevent the invasion of cercariae. Using fatty acid as substrate, saponification with alkali, adding 2% niclosamide and turpentine to make protective agent, it can kill cercariae. Schistosome vaccine has been used in domestic animals. In recent years, the development of schistosome vaccine may produce an effective vaccine suitable for human.

matters needing attention

Generally speaking, for areas with relatively backward public health, the probability of schistosomiasis is relatively high, because their environmental health is worse, so if we want to prevent schistosomiasis, we should first explain personal hygiene, which is very important.
