In order to implement the relevant requirements of the "Healthy China 2030" Planning Outline and the Action Plan for Accelerating the Realization of the Schistosomiasis Elimination Target (2023-2030), the National Bureau of Disease Control and Prevention has designated April 8-14, 2024 as the Schistosomiasis Prevention and Control Publicity Week. This year's theme is "Inheriting the Spirit of Blood Prevention and Accelerating the Process of Elimination".
As the temperature rises
Playing in the water naturally becomes
One of the many fun items for adults and children
But what people don't know is
In the process of playing in the water,
It is possible to be infected with schistosomiasis
Don't take this disease lightly
Recently, Guangdong CDC has issued a reminder
Commonly known as "big belly disease", the late stage of infection has a large belly like 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".
so
How schistosoma is transmitted
Is it possible to be exposed to it in daily life?
Attention! Schistosoma spreads like this
(1) A person or animal infected with schistosomiasis excretes feces containing schistosomiasis eggs into the water;
(2) the intermediate host of schistosomiasis transmission, the snail, lives in the water, and then produces cercariae that can infect humans;
Snails
(3) Human contact with water bodies containing cercariae (infested water).
Life history of blood flukes
It can be infected after 10 seconds of contact with infested water
According to Guangdong Disease Control and Prevention, the most direct cause of schistosomiasis infection is contact with water bodies containing schistosomiasis cercariae without protection.
Daily behaviors, such as production (rice planting, grass cutting, catching fish and shrimp, etc.), life (washing, washing vegetables, swimming, playing in the water, etc.) contact with infected water, or direct drinking of infected water. In just 10 seconds, small bugs will burrow into the human body through the skin and mucous membranes and cause infection!
After infection, it is 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 2 things to prevent schistosomiasis
Keep away from infested 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;
Remind:
Prompt medical attention is key
Exposure to infected water for about a month
If you have symptoms such as fever and diarrhea,
Go to a hospital or schistosomiasis control facility as soon as possible,
Conduct examinations, treatments, or consultations.
