Dengue Fever Test: Symptoms, Causes and Treatment

Dengue fever test is a mosquito-borne disease that occurs in tropical and subtropical regions of the world. Gental dengue fever causes a high fever and flu-like symptoms. A serious form of dengue fever, also called dengue fever, can cause severe bleeding, sudden drop in blood pressure and death. Millions of cases of dengue occur worldwide each year. Dengue fever is most common in Southeast Asia, islands in the western Pacific, Latin America, and Africa. But the disease has been spreading to new areas, including outbreaks in Europe and parts of the southern United States.

Dengue fever is transmitted by the bite of the Aedes mosquito infected with the dengue virus. A mosquito can be infected by biting a person who has dengue virus. It cannot be transmitted directly from person to person.

Symptoms of Dengue Fever

Most people do not have any signs or symptoms of dengue infection. When symptoms occur, they may be affected by other illnesses such as the flu and usually start four to 10 days after being bitten by an infected mosquito.

  • Headache
  • Muscle, bone or joint pain
  • Nausea
  • Vomiting
  • Pain behind the eyes
  • Swollen glands
  • Rash

Sometimes, symptoms are mild and can be mistaken for those of the flu or another viral infection. Younger children and people who have never had the infection before tend to have milder cases than older children and adults. However, serious problems can develop. These include dengue hemorrhagic fever, a rare complication characterized by high fever, damage to lymph and blood vessels, bleeding from the nose and gums, enlargement of the liver, and failure of the circulatory system. The symptoms may progress to massive bleeding, shock, and death. This is called dengue shock syndrome (DSS).

People with weakened immune systems as well as those with a second or subsequent dengue infection are believed to be at greater risk for developing dengue hemorrhagic fever.


Dengue fever is caused by any of the four types of dengue virus. You cannot get dengue fever by close contact with an infected person. Instead, dengue fever is spread by mosquito bites.

Two types of mosquitoes that commonly transmit dengue fever rash are common in and near human settlements. When a mosquito bites a person with dengue virus, the virus gets infected. Then, when an infected mosquito bites another person, the virus enters the person’s bloodstream and causes infection.

After recovering from dengue fever test, you have long-term protection against the virus that infects you but not the other three strains of dengue virus. This means that you can be infected again in the future with one of three viruses. Your risk of getting dengue fever increases if you get dengue fever rash for the second, third or fourth time.
