Beware of dengue fever
Dengue fever is an acute infectious disease caused by the bite of Aedes mosquitoes, which is widely distributed in our region, and once there are dengue fever cases imported, it is easy to cause the spread of the epidemic. There have been imported cases of dengue fever in our area all year round, and there have also been outbreaks caused by imported cases of dengue fever.
The typical clinical manifestations of dengue fever are sudden high fever, which often lasts for a week, headache, orbital pain, muscle, joint and bone pain, hemorrhagic rash on the skin of the face, neck, chest and limbs, and symptoms such as conjunctival hyperemia, lymphadenopathy and bleeding gums, which can lead to hemorrhage, shock and multi-organ dysfunction, and even life-threatening. The incubation period of dengue fever is generally 3~15 days, and most of them are 5~8 days.

Since the beginning of this year, the global dengue fever epidemic has been particularly serious, especially the outbreak of dengue fever in South America, so far, Brazil has reported more than 3 million dengue fever cases, more than 700 deaths, and the cases in Southeast Asian countries adjacent to our region have also increased exponentially.
The epidemic of dengue fever mainly occurs from May to November, and the recent increase in temperature and rainfall in our area has created favorable conditions for the spread of dengue fever. Since there is no vaccine to prevent dengue fever, and there is no effective treatment, only symptomatic treatment, therefore, the most important thing to prevent dengue fever is to avoid mosquito bites!

1. Do a good job of mosquito prevention at home. Install screen doors and windows, and use mosquito nets in bedrooms.
2. Clean up stagnant water in your home to prevent mosquito breeding. If you have the habit of raising aquatic plants, change the water and clean the container regularly in time to avoid mosquitoes from breeding in the water.
3. Pay attention to travel tips before traveling, and prepare for epidemic prevention and control and mosquito prevention in advance.
4. When going out, do a good job of mosquito prevention, wear light-colored long-sleeved and mosquito-proof pants, and carry mosquito repellent with you to avoid mosquito bites.
