Dengue fever is an acute insect borne infectious disease caused by the dengue virus, also known as "bone fracture fever" due to its intense pain. How does dengue fever spread? Dengue fever is an acute infectious disease transmitted through the bite of the vector Aedes mosquitoes, mainly transmitted through the route of "patients → Aedes mosquitoes → others", and the disease is generally not directly transmitted from person to person. After dengue fever patients or latent infected individuals are bitten by Aedes mosquitoes, the virus generally needs to proliferate in the mosquito body for about 8-10 days before it can be transmitted to humans through the bite. The Chinese population is generally susceptible, and the incubation period after infection is generally 1-14 days, but there are also some people who do not develop the disease (referred to as latent infections). The vector Aedes mosquitoes that can transmit dengue virus are widely distributed in China, and the virus can quickly spread and spread after importation. What are the symptoms of dengue fever? The typical symptoms of dengue fever are high fever, triple pain, triple redness, and rash. High fever: sudden high fever (above 40 ° C); Three types of pain: severe headache, joint pain throughout the body, and muscle soreness; Three reds: face red, neck red, chest red; Rash: Congestive rash or punctate bleeding rash on the limbs, trunk, or head and face.
