Please design three protocols to prevent the spread of schistosomiasis

Schistosomiasis is based on comprehensive management, scientific prevention and control, and local conditions.

The main control measures for schistosomiasis are as follows:

Investigation and treatment: Regularly conduct schistosomiasis screening of people who come into contact with infected water to find infected people.

Promptly**. This measure is important for the control of the progression of schistosomiasis to chronic, advanced stages and control the source of infection.

Prophylactic medication: In the case of high-frequency and large-scale exposure to infected water, preventive medication should be carried out for personnel who come into contact with infected water to reduce the occurrence of "urgency".

Water supply and toilet reform: ensure water hygiene and safety and reduce schistosomiasis infection caused by domestic water by using urban tap water, switching to well water or disinfection of river, river and lake water; Switch to non-hazardous latrines to reduce faecal contamination of water bodies and control the spread of schistosomiasis.

Personal protection: wear protective equipment (high rubber shoes, protective gloves, protective clothing, etc.) during production operations; Apply protective drugs (anti-larvae, etc.) to reduce and alleviate infection.

Snail detection and snail extermination: snail detection and snail elimination in areas where grassroots sites and construction sites are already prone to infection to eliminate the transmission vector of schistosomiasis.

1. Try to avoid or reduce contact with infected water: when you have to contact infected water, you can wear protective equipment or apply protective cream to prevent schistosomiasis cercariae from invading the human body.

2. Wear protective equipment: such as wrapping cloth leggings, wearing long rubber shoes, water pants, etc., can prevent schistosomiasis cercariae from invading the human body; The use of blood armor, gloves, socks, leggings, etc., soaked in 1% niclosamide provides better protection.

3. Rubbing protective drugs include: skin avoidance, anti-larvae cream, dibutyl phthalate emulsion and ointment, etc. Most of the drugs can only last for about 4 hours. If the water is used for a long time, the number of applications should be increased.

Method

**Safe and effective drugs for schistosomiasis are praziquantel, etc. As long as you go to the blood prevention department for timely examination, **, schistosomiasis can be cured.

Schistosomiasis eggs are usually found in the feces of sick and sick animals, and eggs can only hatch in water, so it is important to manage human and animal feces and graze safely to avoid feces entering the water to prevent the spread of schistosomiasis.

Snails are the only intermediate host of schistosomiasis, so eradication of snails can effectively interrupt the transmission of schistosomiasis. The masses in the epidemic areas should be done by everyone, cooperate with all parties, and actively do a good job in checking and eliminating snails.

The above content refers to**People** - How to prevent and**schistosomiasis?

1. Do not swim, play in the water, grass, fish, laundry, washing vegetables and other activities that come into contact with infected water in lakes, ponds, and canals with snails. When it is necessary to come into contact with infected water for production and life flood control, measures such as applying protective ointment and wearing protective equipment should be taken to prevent infection with schistosomiasis. After contact with infected water, it is necessary to go to the local hospital or schistosomiasis control institution for examination and early **, and the patients who are detected should be actively ** under the guidance of a doctor.

2. The people living in the epidemic area should actively cooperate with the local schistosomiasis prevention and control institutions to carry out the work of snail inspection, snail extermination, disease investigation and treatment, as well as the work of disease investigation and treatment of livestock. 3. It is an important measure to prevent the spread of schistosomiasis by improving water supply and toilets, preventing feces from polluting water sources, ensuring the safety of drinking water, and changing production and living habits that are not conducive to health.

Ways to prevent the spread of schistosomiasis:

1.Do not swim or play in lakes, ponds, or canals where snails are distributed.

2.For those who are inevitably exposed to infected water due to production and life, they can apply protective ointment before contact with infected water to prevent schistosomiasis infection.

3.After contact with the infected water, it is necessary to go to the local blood prevention department in time for necessary examination and early **.

Schistosomiasis is a chronic parasitic disease caused by Schistosoma schizosomes, which is mainly endemic in 73 countries in Asia, Africa and Latin America, affecting about 200 million people.

There are two main types of schistosomiasis, one is intestinal schistosomiasis, which is mainly caused by Schistosoma mansoni and Schistosoma japonicum; The other is urinary schistosomiasis, which is caused by Schistosoma haematoidosis. The main epidemic in our country is Japanese schistosomiasis.

Do not touch the infected water, do not drink the infected water, and do not use unsterilized sanitary medical equipment, such as syringes, etc.

Schistosomiasis", I believe that many people will be creepy and very uncomfortable when they hear this name. Indeed, schistosomiasis is a major infectious disease that seriously endangers people's health and hinders social and economic development.

For those of us who are old and in their teens, we may be relatively unfamiliar with the disease of schistosomiasis, but we have only seen it on TV or in books, which shows that we have done a relatively successful job in the prevention and control of schistosomiasis. You may not be able to imagine that before the 50s of the 20th century, due to the very serious epidemic of schistosomiasis in our country, it caused a large number of deaths of residents in the disaster area, the bodies of countless patients were destroyed, and the disaster area was full of barren and miserable conditions.

If you want to cure a disease, you must first solve the source of the disease, and then you can prescribe the right medicine. Schistosomiasis is no exception, and in order to be effective, it is necessary to understand how it spreads. Through the Internet, I learned that schistosomiasis must be transmitted through the following three conditions:

1. Feces into the water. 2. Snail breeding. 3. Contact with infected water.

As long as the transmission route is effectively cut off, the disease can be well prevented. It is easier for us to avoid faecal contamination of water sources and contact with infected water, so I think the key to preventing schistosomiasis is to kill snails, which are the only intermediate host of schistosomiasis. Without snails, schistosomiasis cannot be transmitted.

If schistosomiasis is to be eradicated, snails must be eradicated.

Snail extermination is a long-term and arduous work, and the plan should be carefully formulated according to the human and financial resources. Investigate the distribution of snails and implement drugs to kill snails. When exterminating snails, it is necessary to adhere to the principle of first upstream and then downstream, from near to far, first easy and then difficult, extinguishing one piece, clearing one piece, consolidating one piece, focusing on eliminating snails in susceptible areas where people and animals often visit near residential areas, and as far as possible, in combination with farmland and water conservancy infrastructure, to thoroughly transform the environment of snails.

Preventing schistosomiasis is everyone's responsibility. Students, let's take action and eradicate schistosomiasis together!
