Common sense of dengue fever prevention and treatment

First, the management of mosquito breeding grounds.

Turn the basin upside down and remove the idle and useless water; Remove sanitary dead corners and garbage; Managing stagnant water in drinking water or functional containers; For vases planted with aquatic plants, change the water once every 5 -7 days, rinse the roots of the plants, thoroughly clean the inner wall of the container, leave no stagnant water in the flowerpot cushion cover, seal the pipeline wells in the municipal pipe network, the collecting wells in the basement or underground garage and the stagnant water in the construction site, and put in long-acting mosquito killer to control mosquito breeding. Second, eliminate adult mosquitoes.

It is best to kill mosquitoes about half an hour before sunrise and sunset. Pyrethroid insecticides with high efficiency and low toxicity can be selected as chemical insecticides, and sprayed per square meter 15 mg -20 mg in space to kill mosquitoes. Indoor pesticides are sprayed on dark corners and the back of wardrobes to kill mosquitoes. Third, do personal protection.

When working outdoors, you should wear long-sleeved clothes or apply mosquito-repellent incense oil to your skin; Anti-mosquito measures such as hanging mosquito nets, installing screen doors and screens should be taken during the day and night; Use mosquito-repellent incense, aerosol and other household sanitary insecticides to prevent mosquitoes and kill mosquitoes. Extended data:

Symptoms of dengue fever Dengue fever is an acute infectious disease caused by dengue virus, which is spread by Aedes mosquitoes (commonly known as spotted mosquitoes).

Dengue fever does not spread directly from person to person, nor through air or contact. There is no vaccine to prevent it at present. Its incubation period is usually about 5 -7 days, which has the characteristics of fast spread and high incidence.

Because the disease is spread by mosquitoes, its epidemic has certain seasonality, and it generally peaks in May-165438+ 10 and July-September every year. Sudden onset, rapid high fever (up to 39℃-40℃, a few with bimodal fever); "Three pains" (head, eyes, muscle joints) and symptoms such as fatigue; "Three redness" (flushing on face, neck and chest, conjunctival congestion); Diversity rash (measles-like, scarlet fever-like); Bleeding tendency; White blood cells decreased significantly or platelets decreased.

2. Tips for preventing dengue fever

Tips for preventing dengue fever.

Hot and rainy weather is suitable for mosquito breeding, and various small ponding caused by rainfall is the favorite breeding ground for Aedes mosquitoes that spread dengue fever. People should pay attention to anti-mosquito measures in their daily lives and take actions to prevent dengue fever scientifically.

First, mosquito knowledge spreads that Aedes mosquitoes mainly bite people during the day, especially around sunrise 1-2 hours and around sunset 2-3 hours, which is the biting peak of Aedes mosquitoes. Second, the home environment pays attention to clear water, no water, no mosquitoes, no mosquitoes and no dengue fever.

Aedes mosquitoes like to lay eggs in clean small water bodies. Therefore, after it rains, friends should pay attention to finding small stagnant water around their homes and clean it up in time so that Aedes mosquitoes have no breeding soil. (1) Every corner of the front and back of the house: Please clean up and remove the accumulated water immediately.

(2) Balcony idle containers: Please pour out the accumulated water in time and turn these pots and pans upside down. (3) Ponds and hydroponic plants at home: slow release of pesticides in the water in the garden fountain; Hydroponics should be replaced quickly, and the roots of plants should be carefully cleaned.

(4) All kinds of water containers, such as drinking fountains and flowerpot bottoms. Home: Please clean up the stagnant water regularly. It is necessary to clean up all kinds of small stagnant water inside and outside the house regularly, such as cleaning the bottom of flowerpots every day, replacing the roots of hydroponic plants regularly and inverting all kinds of idle containers.

Third, pay attention to prevent bites in outdoor activities. When people are outdoors, they should try to wear light-colored long-sleeved underwear and pay attention to applying mosquito repellent containing effective mosquito repellent (DEET) on their skin. Attention should be paid when applying: ● Do not touch the wound, do not touch the eyes and mouth, and use less in the ears.

● Don't let the baby paint himself. Spray it on the hands of adults and then on the baby, but don't apply it on the hands of children to prevent it from entering the mouth. ● If the skin is allergic, stop using it immediately.

3. Tips for preventing dengue fever

Part I: How to prevent dengue fever at home and personally.

First, clear the breeding ground of Aedes mosquitoes.

The growth cycle of Aedes mosquitoes is 15 days, which is divided into four stages. The three stages of egg, larva and pupa last about 7~ 10 days and must live in water. Once out of water, the life chain of Aedes mosquitoes is broken and they cannot reproduce. Therefore, the important work of mosquito control is to clean up stagnant water and eliminate breeding grounds.

(a) to prevent water accumulation, eliminate Aedes breeding grounds, and enrich bamboo and other green water plants vases. Change water 1 time every 5 ~7 days, and wash the roots of plants. If there are large aquatic plants, put mosquito killer in the water.

(2) The drinking water tank or other drinking water container should be covered, and the water should be changed every 5~7 days 1 time. If you can't change the water regularly, you can raise mosquitoes and fish and cover the well.

(3) The water tray at the bottom of the refrigerator should be cleaned once a week.

(4) Water storage buckets and tanks in bathrooms and toilets. Clean and change water every 5~7 days.

(5) The flowerpot chassis should be kept dry.

(6) Water storage buckets, clay pots, drainage troughs, etc. Clean and replace every 5~7 days, and all channels should be kept clear.

(7) Waste tires should be stored indoors or in a rain-proof place. If it is to be stacked outdoors, it should be covered tightly with a tarpaulin to prevent rainwater from accumulating. If necessary, insecticide can be sprayed on adult mosquitoes, and larvicides such as malathion and parathion can be used in tires.

(eight) the top of the bamboo fence, tree holes and bamboo holes should be blocked with lime sand, or bamboo tubes with roots should be left. Adopt the method of "cross" machete to make it have cracks and no water.

(nine) the water in the gutter or the anti-hill blockage should be cleaned regularly.

(ten) drinking water tanks for poultry, livestock and birds should be cleaned every day.

(eleven) to remove the surrounding pots, cans, bottles and other abandoned containers, unused containers should be inverted one by one.

(12) Fill all depressions on the ground to prevent water accumulation.

Second, eliminate adult mosquitoes.

Use household insecticides to kill adult mosquitoes, and use appropriate dosage according to the packaging instructions. Be careful not to spray pesticides directly to running electrical appliances or places with flames to avoid explosion.

Third, personal protection.

(a) Install mosquito nets on windows. If there is no air-conditioning equipment indoors, mosquito nets or other anti-mosquito equipment should be installed.

(2) During the frequent occurrence of "spotted mosquitoes", you should avoid staying in the shade, grass, pavilions and other outdoor places.

(3) When traveling or working in dengue endemic areas, you should wear light-colored long-sleeved shirts and trousers, or spray mosquito repellent drugs on exposed skin and clothes.

Part II: Dengue fever prevention knowledge.

First, the origin of dengue fever

Dengue fever is an acute infectious disease caused by dengue virus and spread by Aedes mosquitoes. Patients and recessive infected people are the main sources of infection. The disease was found in Cairo, Egypt, Jakarta, Indonesia and Philadelphia, USA from 65438 to 0779, and was named joint fever and fracture fever according to its symptoms. 1869 was named dengue fever by the Royal College of Physicians in London, England.

Second, how is dengue fever spread?

The media is mainly Aedes mosquitoes. After people are bitten by Aedes mosquitoes with dengue virus, they will spread the virus to people and cause diseases.

What are the symptoms of dengue fever?

Patients often have sudden onset, accompanied by chills and fever (up to 39 ~40 degrees in 24~36 hours), accompanied by fatigue, nausea, vomiting and other symptoms; Some patients have severe headache, orbital pain and muscle, joint and bone pain; Face, neck, chest redness, conjunctival bleeding. Superficial lymphadenopathy Three to seven days after onset, the patient developed a rash on limbs, trunk or head and face, and felt itchy. Some severe patients may have multiple organ hemorrhage, hepatomegaly and shock.

Fourth, how to prevent dengue fever?

The focus of prevention is to control mosquitoes and kill mosquitoes. To minimize mosquito breeding, the following measures can be taken:

(1) Indoor mosquito killing: rummaging through cabinets, removing small stagnant water, storing water to plant flower bonsai, changing water regularly every week, and advocating planting evergreen bamboo with wet sand or sealing vase mouths; Containers that can accumulate water are not stacked in the open air to prevent mosquitoes from accumulating water; Spray mosquito repellent, rub toilet water on your body, use mosquito screens, screen doors and screens, and put mosquito nets before going to bed to prevent mosquitoes. Some flowers, such as jasmine, azalea, calendula and mint, can also be used to repel mosquitoes.

(2) Outdoor mosquito control: Fill, cover, close and remove the main mosquito breeding places such as sewage ditches, waste ponds, sewers and construction sites to prevent mosquito breeding. Chemical insecticides such as fenthion and cartap can also be used to kill mosquitoes.

(3) Tips: Summer and autumn are the high incidence seasons of dengue fever. Please rummage through pots and pans to remove stagnant water and mosquito breeding grounds. If you have high fever, headache, muscle pain and other symptoms, please go to the hospital in time.

4. How to prevent dengue fever?

To prevent dengue fever, the most important measures are to kill mosquitoes, clear mosquito breeding grounds, and at the same time do personal protection to prevent mosquito bites.

Aedes aegypti mainly breeds in indoor water containers, while Aedes albopictus mainly breeds in water in flowerpots, jars, tree holes, waste tires, vases and containers in construction sites. Generally, the elimination and control of Aedes aegypti and Aedes albopictus mainly focus on the elimination of breeding grounds and larvae. Mosquito control measures mainly include: 1. Mosquito larva killing: mobilize students, housewives and families to work together, pour the accumulated water into vases and flowerpots filled with rich bamboo and evergreen, clean the roots and change the water once every 3-5 days.

Put the fish in a flowerpot rockery and swallow the mosquito larvae. Gasoline can be added to a large area of stagnant water to suffocate the larvae.

Turn over pots and cans, fill tree holes, wash drinking water containers frequently, change water frequently, and stick mosquito repellent. Mosquitoes can also be killed by stocking mosquito-eating fish in water tanks or other biological methods. For the stagnant water that is difficult to be completely removed in non-drinking containers, you can spray gutter oil or slow-release pesticides.

Dredge ditches and sewers to prevent water accumulation, fill depressions, and rummage through pots and pans to eliminate water accumulation. Second, eliminate adult mosquitoes: indoor spraying or application of non-toxic pesticides to eliminate adult mosquitoes.

The places to be sprayed are house shadows, curtain cloth, dado, etc. On the basis of doing a good job in outdoor environmental sanitation, we should focus on using pesticides in bamboo, Woods, pottery yards, waste tire accumulation stations and other places where there are many adult mosquitoes.

At present, the following kinds can be used: 1, dichlorvos: the medicine can be diluted, sprayed and smoked, which is characterized by quick effect and quick killing of adult mosquitoes. Toxic to humans and animals.

Be careful when using and pay attention to safety. 2. Triclosan (7504): low toxicity to people and livestock, and can be diluted with drugs, sprayed and smoked. It is characterized by slow effect, but it lasts for a long time, and it is still effective in 7~ 10 days.

It can be mixed with dichlorvos in the ratio of 4: 1 or 3: 1. Its advantages are quick-acting and long-lasting.

5. What are the preventive measures for dengue fever?

The distribution control and elimination of Aedes aegypti and Aedes albopictus are the most effective preventive measures at present.

Aedes aegypti mainly breeds in indoor water containers, while Aedes albopictus mainly breeds in water in flowerpots, jars, tree holes, waste tires, vases and containers in construction sites. The elimination and control of Aedes aegypti and Aedes albopictus are generally based on the elimination of breeding grounds and larvae.

Mosquito control measures mainly include: 1, killing breeding grounds and larvae: turning over pots and cans, filling tree holes, washing drinking water containers frequently, changing water frequently, and covering mosquitoes. Mosquito larvae can also be eliminated by releasing fish or other creatures that eat mosquito larvae in water tanks. For the stagnant water that is difficult to be completely removed in non-drinking containers, you can spray gutter oil or slow-release pesticides.

2. Killing adult mosquitoes: indoor spraying or application of non-toxic pesticides to kill adult mosquitoes. On the basis of doing a good job in outdoor environmental sanitation, we should focus on using pesticides in bamboo, Woods, pottery yards, waste tire accumulation stations and other places where there are many adult mosquitoes.

As of 20 1 1, there is no vaccine to prevent and treat the disease, so the best prevention method is to remove the accumulated water in the home, school, workplace and nearby to prevent mosquito breeding and avoid being bitten by mosquitoes.
