What are dengue cases

summary

Last summer, a friend had a fever. Later, he got dengue fever. So, what is dengue fever? Let's talk about it.

What are dengue cases

First of all, dengue fever is a disease caused by dengue virus, and it is a disease transmitted by mosquitoes. After getting the disease, patients will suddenly have high fever, muscle pain, bone marrow and joint pain, and extreme fatigue. Some patients may have rash, bleeding tendency and lymphadenectasis.

Secondly, patients and latent infection were the main sources of infection, and no healthy virus 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. During the epidemic period, the number of mild patients was 10 times of that of typical patients, and the number of recessive infection was 1 / 3 of the population, which may be an important source of infection. Although there was serological evidence of dengue virus infection in monkeys in jungle and mountainous areas and some livestock in cities, it has not been determined as the source of infection.

Finally, the susceptible population is generally susceptible in the new epidemic area. In 1980, the lowest age was 3 months in Guangdong, the largest was 86 years old. Incidence rate was highest in young adults. In endemic areas, 100% of the residents over 20 years old can detect neutralizing antibodies against dengue virus in their sera, so most of them are children.

matters needing attention
