　　Let’s get to know each other!

　　Beware of these two deadly mosquitoes!

　　Dengue fever is also called "bone fracture fever" because it will cause severe pain after infection. Dengue fever is not "human-to-human", and the mode of transmission mainly depends on the bite of two "flying insects"-Aedes albopictus and Aedes aegypti.

　　Only when mosquitoes suck the blood of infected people and replicate the virus in their bodies, can they spread the virus when they bite others next time, that is, the transmission path of "patients → Aedes → others".

　　How to judge whether you have dengue fever?

　　Typical symptoms of dengue fever can be summarized as follows:

　　Sudden high fever: the body temperature can rise to 39 or 40 degrees Celsius within 24 to 36 hours.

　　Three reds: flush on face, neck and chest.

　　Three pains: severe headache, joint pain all over the body and muscle aches.

　　Rash: Congestive rash or punctate bleeding rash appears on the trunk, head and face of limbs.

　　At present, there are no vaccines and specific drugs!

　　At present, there is no approved and registered vaccine for dengue fever, which means there is no way to prevent dengue fever by vaccination.

　　At the same time, there is no specific antiviral drug at present, and symptomatic treatment measures are mainly taken. The treatment principle is early detection, early diagnosis, early treatment, early mosquito prevention and isolation. Early identification and timely treatment of severe cases are the key to reduce mortality.

　　The best way to prevent dengue fever

　　Pay attention when entering the country, and report to the customs immediately if there is fever.

　　Pay attention within 14 days after returning home, seek medical advice immediately if you have fever, and inform your travel history to avoid delaying your illness and causing serious illness.
