Understanding the Identification and Prevention of Dengue Fever
The Millennium has passed.
The weather is still hot
Many mosquitoes continue to attack everywhere.
As the "first brother" of mosquito-borne infectious diseases
Dengue fever has been mentioned frequently recently.
Today we put
Identification, prevention and harm of dengue fever
Make it clear at once
01
What is dengue fever?
Dengue fever is an acute mosquito-borne infectious disease caused by dengue virus, which is also called "bone fracture fever" because of its severe pain.
01
How is dengue fever spread?
Dengue fever is mainly transmitted by the bite of Aedes aegypti and Aedes albopictus.
Generally, it will not be transmitted from person to person. Only when a dengue fever patient is bitten by a mosquito in the infectious stage, this mosquito may carry dengue virus.
When this mosquito bites others again, it will spread the dengue virus to others. So mosquitoes are the bane!
02
Where do Aedes mosquitoes often appear?
Aedes albopictus mostly inhabits near breeding sites, mainly in various artificial and plant containers. Such as: indoor and outdoor water tanks, bamboo tubes in bamboo forests, tree holes, waste tires, pickled ceramic utensils, etc.
03
What are the habits of Aedes mosquitoes?
Most of them invade the human body outdoors, and the peak of blood sucking is usually from early morning to 10 am and from 4 pm to dusk.
The flight range of activities is generally 50 ~ 100 meters near the breeding ground, and rarely exceeds 200 meters. Therefore, it is easy to be bitten when it is within 100 meters around its breeding ground during the peak period of its activity.
04
How do I know if I have dengue fever?
The typical symptoms of dengue fever are high fever, "three redness", "three pains" and rash.
High fever: sudden fever, the body temperature can reach above 39℃.
"Three reds": face red, neck red and chest red.
"Three pains": severe headache, orbital pain and joint muscle pain.
Rash: Congestive rash or punctate bleeding rash appears on the trunk or head and face of limbs.
If you have a history of traveling in an epidemic area of dengue fever within 2 weeks, or if there are confirmed cases in the city where you are active, plus "fever, pain, redness and rash", you are likely to have dengue fever.
Is there any vaccine to prevent dengue fever?
Is there any specific medicine for treatment?
At present, there is no effective vaccine to prevent dengue fever, and there is no specific treatment, only symptomatic treatment. Therefore, the simplest and most effective way is to avoid being bitten by mosquitoes and seek medical advice in time.
Is dengue fever fatal? Any sequelae?
Dengue fever is generally a self-limiting infectious disease, with less complications, lower mortality and generally no sequelae. People with chronic diseases, the elderly, infants and pregnant women are at higher risk of serious illness after infection.
02
How to prevent dengue fever?
The bite of Aedes mosquitoes is the only transmission route of dengue fever, so reducing the number of Aedes mosquitoes or avoiding bites is the key to prevent and control the spread of dengue fever. Mosquito control is the fundamental method to prevent dengue fever.
Step 1 clear stagnant water
Keep the living environment clean and tidy, and "turn over pots and cans" to remove all kinds of useless accumulated water such as indoor and outdoor idle containers and flowerpot bottoms.
Aquatic plants should change water regularly (every 3-5 days).
2. Kill adult mosquitoes
Install mosquito nets, screen doors, screens, etc.
Timely use mosquito-repellent incense, electric mosquito-repellent incense, electric mosquito swatter, mosquito-repellent lamp and other equipment, and you can also use insecticidal spray to kill mosquitoes in the room.
Step 3 do protection
Individuals can use mosquito repellent on their clothes, wear light-colored long-sleeved shirts and trousers, and do not use odorous cosmetics and perfumes when outdoors.
Avoid staying in the shade of trees, grass, pavilions and other outdoor places during the period when mosquitoes frequently appear (usually between early morning and 10 am and between 4 pm and dusk).
Special reminder
If you have fever, headache, orbital pain, muscle joint and bone pain, and related symptoms such as flushing and rash on face, neck and chest, you must go to the designated hospital as soon as possible.
And inform the doctor about the recent work or travel history abroad and outside the province, and cooperate with the development of dengue related testing.
