Dengue fever is coming, you need to know these "fever" knowledge! Share it with people around you!

Dengue fever may seem a little strange to everyone. Compared with the flu we are exposed to every day, it seems very far away from us. As its name suggests, dengue fever is widely distributed in tropical and subtropical regions , and is most prevalent in the Western Pacific and the Americas.

But in fact, it is not far away from us. It also occurs frequently in Guangdong, Fujian, Hainan and other regions in China. The epidemic season of dengue fever is mainly from May to November . With the large-scale reproduction of mosquitoes, dengue fever will also usher in a high-incidence season.

Seeing this, some friends may wonder: "What is the connection between dengue fever and mosquitoes?"

Experts from You County People's Hospital said that dengue fever is an insect-borne infectious disease caused by the dengue virus . Its main vectors are Aedes aegypti and Aedes albopictus. It is transmitted through the pathway of " patients/hidden infected persons - Aedes mosquitoes - healthy people ", and it is not directly transmitted between people. After sucking the blood of an infected person, the mosquito replicates the virus in the body, and after 8 to 10 days of proliferation, it transmits the virus to healthy people through bites.

Aedes aegypti mainly live in dark, sheltered places , such as the feet of water tanks, behind cupboards, under bedrooms, in corners, etc. The stagnant water in flower pot trays may also become a breeding ground for mosquitoes. They grow rapidly and become the "carriers" of the virus.

Theoretically, every time a mosquito carrying the dengue virus bites a person, it can infect the person. Therefore, popularizing dengue fever and killing mosquitoes has become a top priority.

So, how should we prevent dengue fever in our daily lives?

1. Pay attention to the hygiene of your home , keep it clean and dry, and have electronic mosquito repellents, electric mosquito swatters, mosquito coils and other mosquito repellent tools at home. You can install mosquito nets, screens, etc.

2. When going out, wear light-colored long-sleeved shirts and long pants, apply mosquito repellent on exposed skin, and avoid staying in the shade of trees, grass, pavilions, etc.

3. If you develop high fever after being bitten by mosquitoes (body temperature may reach above 40°C within 24 hours, may be accompanied by chills, generally lasting 3-7 days), severe body pain (headache, orbital pain, musculoskeletal joint pain), flushing of the skin of the face, neck, and chest, congestive rash or punctate hemorrhagic rash on the limbs, trunk, head and face, and other obvious symptoms of dengue fever, please go to the hospital for medical treatment in time, actively inform the doctor of your travel history , cooperate with dengue fever-related monitoring , and avoid becoming a source of infection of the virus.

There is a common joke on the Internet that "Hunan people's coming of age ceremony is a train ticket to Guangdong", so Guangdong has become the second home of Hunan people.

As the National Day approaches, a large number of people who have been away from home return home. In order to further improve the prevention and control of dengue fever and enhance the diagnostic sensitivity of medical staff to dengue fever, You County People's Hospital organizes medical staff from various departments to receive dengue fever prevention and control training. Cleaning staff regularly conduct comprehensive disinfection of the hospital, and the fever clinic is specialized in treatment to achieve "early detection, early diagnosis, early mosquito prevention and isolation, and early treatment" to build a solid health line of defense.
