How to get rid of blood-sucking bugs on the bed

Schistosomiasis is a relatively serious parasitic disease in daily life, which endangers human health and is widely prevalent. The human body is infected when it comes into contact with water. It mainly parasitizes in the arterial system and can cause many diseases, such as: fever, fear of cold, loss of appetite, diarrhea, etc. There are usually no obvious symptoms in the chronic stage. If you experience these symptoms, go to the hospital for treatment immediately. How can we eliminate blood-sucking bugs if we have them in our beds?

1. Expose the bed bugs to strong sunlight for 1 to 4 hours and turn them over to kill them by the high temperature or by crawling out.

2. Manual capture: knock on the bed frame, bed board, kang mat, straw mat, etc. to shake the bed bugs off and kill them, or use a needle or wire to pick out the bed bugs in the gaps and kill them.

The most obvious symptoms of schistosomiasis:

The onset is acute, with symptoms such as chills, fever, abdominal pain, diarrhea, loss of appetite, and mild enlargement of the liver and spleen. Repeated infection with schistosomiasis usually manifests as chronic schistosomiasis. In mild cases, there are no subjective symptoms. Severe cases often present with abdominal pain, diarrhea, bloody stools, and varying degrees of anemia, weight loss, malnutrition, and hepatosplenomegaly. Late-stage patients develop cirrhosis, ascites and portal hypertension. Patients often die from liver damage and massive upper gastrointestinal bleeding.

When people come into contact with water containing schistosome cercariae, the cercariae quickly attach to the human skin. After about 10 to 20 seconds, the cercariae pass through the skin and enter the human body, and the person is then infected with schistosomes. After schistosome eggs fall into the water along with human feces, under suitable temperature and water quality conditions, after a certain period of time, the eggs will hatch into miracidia. The miracidia have many fine hairs all over their bodies and can move. When they encounter a kind of snail called "Oncomelania" in the water, the miracidia will drill into the soft part of the snail that protrudes outward, and develop and reproduce into a large number of cercariae inside the snail's body. The mature cercariae do not stay in the snail's body for long, but can only escape from the snail's body in the presence of water. When the snail is in the water or crawling on the stems and leaves of plants with water droplets, the cercariae leave the snail's body and enter the water. At this time, if people go into the water (such as fishing in lake areas, cutting lake grass, fighting floods, disaster relief, etc.) or walk barefoot on the ridges of fields in the countryside, they may be infected with schistosomiasis. Schistosoma cercariae mainly invade the human body through the skin.

However, according to investigations, drinking raw water containing cercariae can also cause infection with schistosomiasis, indicating that cercariae can enter the human body through the oral mucosa. Once we understand the relationships among snails, cercariae, water bodies and humans, it is not difficult to understand how schistosomiasis is transmitted and why people cannot be infected with schistosomiasis through contact with each other.
