About Dengue

About Dengue: Dengue is a mosquito-borne tropical disease that affects about 400 million people worldwide every year. It is caused by the dengue virus, which is transmitted to humans by a mosquito bite.

The first symptoms of dengue are fever, headache, and pain in joints and muscles. These symptoms usually last for 2-7 days and may be followed by vomiting, nausea, rash or itching. Globally, around half of those infected with dengue fever will have an unpleasant complication called “dengue hemorrhagic fever.” This life-threatening condition can cause bleeding from the nose or gums as well as internal bleeding into the body organs.

Dengue can be prevented by avoiding contact with mosquitoes and wearing protective clothing to cover all parts of the body that are exposed to mosquito bites during the day.

Dengue Symptoms

The symptoms of dengue fever usually start to show after 3-14 days of infection. They can last for about a week and the severity varies from person to person. The most common symptom is high fever which lasts for about 3-7 days. Other symptoms are headache, nausea, vomiting and skin rash.

There are four types of dengue fever: mild, moderate, severe and critical. Mild cases usually do not require any treatment while severe cases may need hospitalization because they can lead to death if not treated quickly enough or with appropriate medicines.

Dengue Transmission

Dengue is a vector-borne disease. It is transmitted to humans by infected female mosquitoes, called Aedes aegypti.

Dengue fever is an acute viral hemorrhagic illness caused by the dengue virus. It is the most prevalent mosquito-borne disease in the world. The virus is transmitted to humans through the bite of an infected female mosquito, called Aedes aegypti, which feeds primarily on human blood.

Laboratory Test

Dengue Test: A laboratory test that detects the presence of dengue virus in the blood or serum of a patient.

NS1 (non Structural Protein) antigen Test

NS1 antigen is a protein that is found on the surface of the dengue virus. It is also found in the blood of people who are infected with dengue. This protein can be detected by a test called ELISA.

The NS1 antigen test is used to diagnose dengue infection and to monitor disease progression and response to treatment.

IgG and IgM Antibody Test

IgG and IgM tests are two different types of blood tests that can be used to identify a dengue infection.

IgM is usually the first antibody to show up in the body. It can be detected within 2-3 days after a person has been infected with the virus. IgG can take 2-3 weeks to show up after infection, and it will stay in the body for life.

The results of these two tests are not always clear, but they are often used together for better accuracy.


There is no specific medicine to treat dengue. Treat the symptoms of dengue and see your healthcare provider.
