01
Commonly known as "pot-bellied disease"
In the late stages of infection, the belly is as large as a bulge
Schistosomiasis is a disease caused by schistosomiasis parasitizing the human body and is listed by the World Health Organization as one of the 21 neglected tropical diseases.
After the human body is infected with schistosomiasis, there is no standardized treatment or repeated infection, and when it develops to an advanced stage, symptoms such as hepatosplenomegaly and ascites will appear, showing skinny and large belly, regardless of men and women.
Therefore, it is commonly known as "big belly" disease.
Patients with advanced schistosomiasis

Attention! Schistosoma spreads like this
①
A person or animal infected with schistosomiasis
Waste the stool containing the schistosoma eggs into the water
②
Schistosomiasis is transmitted in the water
Intermediate Host –
Snails
This then produces cercariae capable of infecting humans
Snails
③
People touched
Water bodies containing cercariae (infested water)
Life history of blood flukes
03
In case of contact with infested water
It takes 10 seconds to get infected
The most direct cause of schistosomiasis infection is unprotected exposure to water bodies containing schistosomiasis cercariae.
Daily behaviors, such as production (rice planting, grass cutting, catching fish and shrimp, etc.), life (laundry, vegetable washing, swimming, playing in the water, etc.) contact with infected water, or direct drinking of infected water -
Just 10 seconds
Small insects will burrow into the body through the skin and mucous membranes
Trigger an infection!
04
After infection
It's easy to mistake it for a "cold"
Some patients may experience a tingling-like sensation on the skin after exposure to the infested water, followed by pimples and itching.
Pimples and itching appear after contact with infected water
● After 1~5 days, there may be cough (easy to mistake for cold), and the lung symptoms of recurrent infection are more serious.
● After an incubation period of 30-60 days, there will be fever, liver enlargement and peripheral blood eosinophilia, accompanied by liver tenderness, spleen enlargement, cough, abdominal distension and diarrhea and other symptoms.
● Patients with recurrent infections who have not been treated with standard treatment can develop advanced schistosomiasis.

Do the following two things
Prevention of schistosomiasis
(1) Keep away from infected water
The direct cause of schistosomiasis infection is contact with water bodies containing schistosomiasis cercariae, and the key to preventing infection is not touching infected water and safe water.
1. Always pay attention to whether there are relevant warning signs on the shore! Try to avoid swimming, playing, laundry, fishing in rivers, lakes, ponds, ditches and other water bodies where there are snails breeding or uncertain risks;
2. Due to the needs of production, life and flood control, it is inevitable to come into contact with the infected water where Schistosoma cercariae may exist, and prevent infection with Schistosoma by wearing protective equipment (rubber gloves, rubber shoes, rubber clothing, rubber pants, etc.), applying protective cream (agent), and taking preventive medicine;
(2) Seek medical attention in a timely manner
If you have symptoms such as fever and diarrhea after about one month of exposure to infected water, go to the hospital or schistosomiasis control institution as soon as possible for examination, treatment or consultation.
