From May, dengue fever enters the epidemic season
According to the National Health Commission, the epidemic season for dengue fever transmission is from May to November every year, and the peak of the epidemic is from July to September.
Specifically, dengue fever is an acute insect-borne infection caused by dengue virus, mainly transmitted by the bite of Aedes mosquitoes, and the epidemic area is mainly distributed in tropical and subtropical regions, with Southeast Asia, the Western Pacific and the Americas being the most serious.
Dengue fever is mainly prevalent in Guangdong, Guangxi, Hainan, Fujian, Zhejiang and other regions in mainland China, and has typical imported and sudden characteristics. The disease spreads rapidly, has a high incidence, and is generally susceptible to the population. The National Health Commission reminds that if you have fever symptoms within 2 weeks after returning from travel, please go to a regular hospital immediately for medical treatment and inform your travel history to avoid delaying your illness and causing severe illness.
Dengue fever is mainly transmitted by "flower mosquitoes".

Dengue fever is mainly transmitted by the route of "patient→ Aedes mosquito → others". Diseases are generally not transmitted directly from person to person.
Currently, dengue virus is mainly transmitted by Aedes albopictus and Aedes aegypti (commonly known as "flower mosquitoes"). After a dengue fever patient or a person with latent infection is bitten by Aedes mosquitoes, it usually takes 8 to 10 days for the virus to multiply in the Aedes mosquito before it can be transmitted to humans through the bite.
The mainland population is generally susceptible to dengue virus, and the incubation period after infection is generally 1 to 14 days (most are 5 to 9 days), but some people do not develop the disease (i.e., those with latent infection). Aedes mosquitoes, the vector that can transmit dengue virus, is widely distributed on the continent and may spread rapidly after importation.
There are 4 typical symptoms of dengue fever
The typical symptoms of dengue fever can be summarized as: sudden high fever + three red signs + three pains + rash.
Sudden high fever: The body temperature can rise to 39 or 40 degrees Celsius in 24 to 36 hours. Three red signs: flushing of the face, neck, and chest. Three pains: severe headache, generalized joint pain, muscle aches. Rash: A congestive or punctate hemorrhagic rash on the extremities, trunk, or head and face.
Avoiding mosquito bites is key to prevention
What can I do to stay away from dengue fever in my life? Avoiding mosquito bites is key! When going outdoors in dengue-endemic areas, try to choose light-coloured, long-sleeved trousers and use insect repellent or other mosquito repellent if possible. In addition, the prevention of dengue fever should also do the following mosquito prevention and control work:
Clean up stagnant water in your home: For example, water plants should be changed regularly to wash bottles (at least once a week), and no stagnant water should be left in the bottom of the pot;
Keep ventilated and dry;
installation of screen doors and windows, use of mosquito nets;
Use insect control products.
Pay special attention to !!
At present, there is no specific drug for dengue fever, and treatment focuses on pain control, timely hydration, prevention of bleeding, and early mosquito isolation.
If you accidentally get infected with dengue virus, don't panic too much. Dengue fever patients generally have a good prognosis and can basically recover after timely treatment, but there are also a few reports of deaths in severe cases, so please be sure to take scientific precautions.
