What is dengue fever

summary

Dengue fever is a high incidence infectious disease in southern China, which is generally transmitted by mosquito bites. However, in our life, many people do not know what dengue fever is. This paper analyzes the problem of what dengue fever is.

What is dengue fever

First of all: dengue fever is an acute infectious disease caused by dengue virus and transmitted by Aedes mosquitoes. Dengue fever attacks rapidly and without signs in clinic. Patients usually have high fever, joint pain and other symptoms, and some patients also have rash, bleeding tendency and lymphadenectasis.

Secondly, patients and latent infection were the main sources of infection, and no healthy carriers were found. From 6-8 hours before the onset to the 6th day of the disease, the patient had obvious viremia, which could infect Aedes biting.

Finally: during the epidemic period, the number of light patients was 10 times of that of typical patients, and the number of latent infection was 1 / 3 of the population, which may be an important source of infection. Although monkeys in the jungle and mountainous areas and some livestock in the city have serological evidence of dengue virus infection, they have not yet been determined as the source of infection.

matters needing attention

After making clear what dengue fever is, we should pay attention to improving the sanitary environment and taking measures to prevent and control mosquitoes.
