What is schistosomiasis? What are the symptoms?

Schistosomiasis, commonly known as "potbelly disease", is an infectious disease and parasitic disease caused by schistosomiasis infection in humans or mammals such as cattle, sheep, and pigs. What activities can get schistosomiasis? In general, from March to November, people can be infected with schistosomiasis as long as they come into contact with infected water containing cercariae, such as rice planting, flood control, shrimp fishing, swimming, washing clothes and vegetables.

The more exposure to epidemic water, the greater the chance of infection. <>

Schistosoma parasitizes humans and mammals. The eggs produced by the adult worms are excreted in the feces, and the cercariae hatch in the water; Cercariae burrow into the body of the snail and develop into cercariae. The cercariae leave the snail and swim into the water.

When they encounter people and animals, they burrow into the body through ** (mucous membranes) and develop into adults. This cycle repeats itself, leading to the spread and epidemic of schistosomiasis. <>

What are the symptoms there?Clinical manifestations of schistosomiasis: the main symptoms in the acute stage are rash, fever, abdominal pain, diarrhea, hepatosplenomegaly, etc. Chronic phase: asymptomatic or chronic diarrhea or dysentery.

Schistosoma is mainly distributed in 346 counties (cities and districts) in 12 provinces, autonomous regions and municipalities directly under the central government, including Shanghai, Jiangsu, Zhejiang, Jiangxi, Fujian, Anhui, Hubei, Hunan, Sichuan, Yunnan, Guangxi and Guangdong. Outbreak: More than 12 million patients, 1.2 million sick cattle and 14.8 billion m of snails.

So how can we prevent schistosomiasis?

Schistosoma japoiconum infects humans through contact with epidemic water. Therefore, avoiding or reducing exposure to infected water in production and life is the most effective way to prevent schistosomiasis.

Residents have access to tap water, well water, etc. For daily use, unsterilized pond and ditch water should not be consumed. If the water is heated above 60 (the temperature at which it feels hot), the cercariae in the water are killed; For every 50 kg of water, 1 gram of bleaching powder, 15 milliliters of 3% iodine tincture or gram of quicklime can be added to kill cercariae.

Practice good hygiene: Humans and animals should not excrete feces in places where there are snails to prevent feces from polluting water sources and ensure safe drinking water.

Schistosomiasis is a parasitic disease in which schistosomiasis inhabit the human body. The main symptoms are abdominal pain, diarrhea, fever, rash, etc. Medications** are generally anthelmintic praziquantel, and patients should ensure adequate rest and nutrition to prevent complications.

The general symptoms are inflammation and fever, there will be a rash all over the body, infectious diseases and parasitic diseases infected by schistosomiasis, schistosomiasis is a flat-shaped animal, which can suck blood, which is very harmful to health.

Schistosomiasis is a chronic parasitic disease caused by Schistosoma schizosome, commonly known as "potbelly disease", the main symptoms of schistosomiasis in the acute phase are rash, fever, abdominal pain, diarrhea, hepatosplenomegaly, etc., and asymptomatic or chronic diarrhea or dysentery in the chronic phase.

Schistosomiasis is a parasitic disease that can cause stomach pain, diarrhea, or blood in the stool.

A tingling-like sensation may be followed by papules and itching within 1 hour to 2 days of schistosomiasis infection with contact with the infested water**. Recurrent infections often have itching and sometimes hives. The pimples and itching last 1-5 days and then resolve on their own.

Infected with schistosomiasis 1 to 5 days may have a cough (easily mistaken for a cold), and patients with repeated infections may have severe lung symptoms. Symptoms of acute schistosomiasis such as fever, hepatic tenderness, hepatosplenomegaly, abdominal pain, and diarrhea may appear 1 month after infection (acute symptoms can appear as early as 2 weeks).

Chronic schistosomiasis may include hepatosplenomegaly and chronic diarrhea. Women infected with schistosomiasis can be infertile and pregnant women can have miscarriages. Advanced schistosomiasis may include hepatosplenomegaly, ascites, dyspnea, upper gastrointestinal bleeding, lower extremity edema, abdominal pain, diarrhea, constipation, etc., and schistosomiasis dwarfs can be seen in endemic areas.

The onset is acute, with chills, fever, abdominal pain, diarrhea, loss of appetite, and mild enlargement of the liver and spleen. Recurrent and repeated schistosomiasis infections most often present as chronic schistosomiasis. Mild cases have no symptoms.

Severe cases often have abdominal pain, diarrhea and mucus and bloody stools, and varying degrees of anemia, emaciation, malnutrition, and hepatosplenomegaly. Patients with advanced disease developed cirrhosis, ascites, and portal hypertension. Patients often die from liver compromise and massive upper gastrointestinal bleeding.

When a person comes into contact with water containing schistosoma cercariae, the cercariae quickly adsorb on the human **, and after about 10 20 seconds, the cercariae pass through the ** into the human body, and the person is infected with schistosomiasis. After schistosoma eggs fall into the water with human feces, under suitable temperature and water quality conditions, after a certain period of time, the eggs hatch out of the larvae, which have many slender hairs around the body and can move, when encountering a kind of snail called "snail" in the water, the larvae will drill into the soft part of the body that extends outward, and develop and reproduce into a large number of cercariae in the body of the snail. When the snail crawls in the water or on the stems and leaves of plants with water droplets, the cercariae leave the snail and enter the water, at this time, if people go into the water (such as fishing in the lake area, hunting lake grass, flood control, disaster relief, etc.) or walk barefoot on the ridge of the countryside, there is a possibility of infection with schistosomiasis.

Schistosoma cercariae mainly invade the human body through **. However, according to research, drinking raw water containing cercariae can also infect schistosomiasis, indicating that cercariae can enter the human body through the oral mucosa. Once we understand the interconnections between snails, cercariae, water bodies and people, it is not difficult to understand how schistosomiasis is transmitted and how people cannot be infected with schistosomiasis.

A: Human schistosomiasis infection is mainly characterized by acute or chronic enteritis, liver cirrhosis, severe diarrhea, anemia, and emaciation.

Schistosomiasis can cause anemia, diarrhea, abdominal pain, dizziness, etc., and in severe cases, death.

Schistosoma has no symptoms in the early stage, but if it is left untreated for a long time, sometimes you will feel weak in your legs and feel weak. If you do not carry out **, depending on your physique, sooner or later you will enter the middle and late stages, liver ascites will appear, and then the belly will become larger, and the limbs will be very thin. If it is carried out**, the disease generally has no effect on the person.

Insistence**,**Do not contact the infected water during and after the process, there is a possibility of **!!

Weakness, emaciation, inability to eat, yellowing of the face, etc.
