The content of preventing schistosomiasis in the fourth grade handwritten newspaper

The contents of the fourth grade handwritten newspaper for schistosomiasis control are as follows:

1, Understanding schistosomiasis: Understanding the living habits, transmission routes and hazards of schistosomiasis, and knowing how to prevent schistosomiasis.

2. Avoid contact with epidemic water: Don't swim or play in the waters of epidemic areas, especially don't let children play in epidemic water. In case of contact with epidemic water, protective measures should be taken, such as wearing protective clothing, gloves and shoes.

3. Do a good job in personal hygiene: maintain personal hygiene, wash your hands frequently, take a bath frequently, and avoid contact with the patient's blood and excrement.

4. Prevent skin damage: Avoid skin soaking in water for a long time, especially in epidemic areas. If you must go into the water, try to reduce the soaking time and take protective measures.

5. Timely treatment of patients: If symptoms of schistosomiasis are found, you should seek medical treatment in time.

Schistosoma japonicum is a parasite of Schistosoma japonicum, also known as Schistosoma japonicum. Schistosoma japonicum is a trematode parasitic in blood vessels. Schistosoma mansoni, Schistosoma japonicum and Schistosoma japonicum are the main parasites in human body. Schistosoma japonicum is prevalent in China. Adults are hermaphroditic, and male and female hugs are necessary for the normal development of children, but neither parthenogenesis nor male infection can develop normally.

The diagnosis of schistosomiasis is to detect parasitic eggs in feces or urine samples. Schistosomiasis is prevalent in tropical and subtropical regions, especially in poor communities without safe drinking water and proper sanitation facilities. It is estimated that at least 90% of patients who need schistosomiasis treatment live in Africa.

Pathogenic principle:

China has Schistosoma japonicum, which is hermaphroditic. The male worm is short and thick, with an average body length of 16mm, showing milky white. The female worm has a slender figure and a slender front end, with an average body length of 20 mm. The back of the worm is dark brown because the intestine is full of digested hemoglobin. Female insects are often located in the female-holding groove of male insects, and parasitize the hepatic portal vein and mesenteric vein system of human and mammals such as cattle, sheep, pigs, rats and rabbits.

Some or all of the surface of hermaphroditic adults have small nodules or spines, and the oral sucker and abdominal sucker are located at the front end of the worm. Worms are adsorbed on the inner wall of veins by suckers, and crawl to the venous end of intestinal submucosa through the attraction and separation of oral and abdominal suckers, where they mate and lay eggs. The egg is ovoid, light yellow, and contains miracidium.
