Dengue virus infection can lead to latent infection, dengue fever, dengue hemorrhagic fever, dengue hemorrhagic fever is rare in China. The typical clinical manifestations of dengue fever are sudden onset, high fever, headache, severe pain of muscles and joints, rash, bleeding tendency, lymphadenopathy, leucopenia, thrombocytopenia, etc.

Second, the disease is mainly prevalent in tropical and subtropical areas. Guangdong, Hong Kong and Macao are endemic areas of dengue fever. Because the disease is transmitted by Aedes, the epidemic has a certain seasonality, generally from May to November every year, and the peak is from July to September. In the new epidemic area, the population is generally susceptible, but the incidence is mainly adult, in the local epidemic area, the incidence is mainly children.

Third: dengue virus belongs to flavivirus in Flaviviridae. It is a single strand positive RNA virus. It is resistant to low temperature and can survive for 5 years at - 20 ℃ and more than 8 years at - 70 ℃. But it is not heat-resistant. It can be inactivated at 50 ℃ for 30 minutes or 100 ℃ for 2 minutes. It is not acid resistant. It can be inactivated with detergent, ether, ultraviolet and 0.65% formaldehyde solution. At present, four serotypes of dengue virus have been isolated.
