What is dengue fever?

How is dengue fever spread?

Dengue fever is an acute infectious disease caused by the dengue virus, which is mainly transmitted by mosquitoes. The peak season is summer and autumn. Patients generally experience symptoms 1 to 14 days after infection. Symptoms include high fever, severe pain, skin flushing, congestive rash or punctate hemorrhagic rash on the limbs, trunk, or head and face. In a small number of patients, the condition further deteriorates and may be life-threatening.

According to Beijing Centers for Disease Control, dengue fever is currently prevalent in tropical and subtropical regions around the world, with the most severe outbreaks in Southeast Asia, the Western Pacific, and the Americas. In China, dengue fever is mainly prevalent in southern China, including Guangdong, Guangxi, Hainan, Fujian, Taiwan, and Zhejiang. The dengue fever season is mainly from May to November.

Dengue fever is a strictly Aedes-transmitted infectious disease, which is continuously transmitted through the route of patients/latently infected persons → Aedes mosquitoes → healthy people. The disease cannot be transmitted directly between people.

How to prevent dengue fever?

How to treat it?

According to the Beijing Center for Disease Control, there is currently no approved and registered vaccine for dengue fever on the market, which means that it is not possible to prevent dengue fever through vaccination.

There is currently no specific antiviral drug, and the main treatment measures are supportive and symptomatic.

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 reducing the mortality rate.

If you travel to a dengue-endemic area

How to prevent dengue fever?

Before going to the epidemic area

Prepare mosquito prevention and killing supplies, such as: mosquito repellent, floral water, mosquito coils, electric mosquito swatters, mosquito lamps, mosquito nets, high-efficiency and low-toxic mosquito repellents, etc.

During the epidemic period

Try to choose light-colored long-sleeved shirts and long pants, and use mosquito repellents and other mosquito repellent products when going out to avoid mosquito bites.

Before going out, you can use mosquito coils, mosquito repellent aerosols, etc. in the hotel room. Even in a hotel, you should pay attention to indoor mosquito control.

If you have symptoms suspected of dengue fever, seek medical attention immediately.

After entering or returning to Beijing

Those returning to the country should actively cooperate with the entry-exit inspection and quarantine department to carry out entry quarantine work and fill out the health declaration card truthfully.

When entering the country, people with symptoms such as fever and rash should proactively report their illness to the entry-exit inspection and quarantine agency, and cooperate with the health quarantine department to conduct investigations and corresponding medical examinations.

If you have fever or other symptoms within 14 days after returning to China or Beijing from an epidemic area, you should seek medical attention immediately. When seeking medical attention, you should proactively inform medical staff of your recent travel history and history of mosquito bites in the local area so that you can receive timely diagnosis and treatment.
