Dengue virus

Dengue virus is a virus from the flavovirus genus, the togavirus family, belonging to the arbovirus ecological group. It causes the fever of the same name, which can be life-threatening. The dengue virus consists of 4 serotypes, which have different antigenic properties and can cause different symptoms in people.

The dengue virus is common in tropical and subtropical regions, where it is transmitted through mosquito bites. The incubation period of the virus can last from 5 to 14 days, after which a person may develop symptoms of fever.

One of the most common symptoms is a high fever. Headaches, muscle pain, nausea and vomiting, skin rashes, and bleeding from the nose and gums may also occur.

Treatment of dengue virus involves taking antiviral drugs and symptomatic therapy. There is no vaccination against the dengue virus, but some countries implement mosquito control campaigns to reduce the risk of infection.

Overall, the dengue virus is dangerous to human health and life, so it is important to take precautions to avoid infection.

Dengue virus: basics of epidemiology and prevention.

The dengue virus is one of the most dangerous and common viruses in the world that affects the nervous system. This type of virus belongs to the causative agents of the same name acute febrile diseases in humans, which have their symptoms increased body temperature, convulsions, jaundice and other damage to the blood and blood vessels.

Epidemiology of the disease The causative agents of the dengue virus belong to the flavivirus family and the togavirus genus. Antibodies that allow immunocompetent cells to produce protective antibodies are activated 20-25 days before the onset of clinical manifestations of infection. If an individual's body contains less than 0.01 mIU (international units) of virus-neutralizing antibodies to dengue virus, infection may develop during an epidemic. In some cases, asymptomatic carriage of the pathogen is possible.

The first symptoms of the disease appear a few days after infection. The maximum growth rate of the disease is observed 135-140 days from the date of infection with the causative agent of the dengue virus; the virus is released from the individual’s body within another 4-5 weeks.
