Dengue cannot be cured although treatments can help get rid of dengue infections.
Also in some cases dengue virus may go away but it can sometimes become life threatening without treatment.
Dengue is caused by a virus.
Dengue viruses are a type of virus that are spread to people through the bite of an infected Aedes species (Ae. aegypti or Ae. albopictus) mosquito.
The dengue virus is a mosquito-borne viral disease occurring in tropical and subtropical areas.
Those who become infected with the dengue virus a second time are at a significantly greater risk of developing severe disease.
Symptoms of the dengue virus are high fever, rash, and muscle and joint pain. In severe cases there is serious bleeding and shock, which can be life threatening.
Treatment for the dengue virus includes fluids and pain-relievers.
Severe cases require hospital care.
Dengue fever usually starts with a fever, joint pain, rash and nausea.
Without treatment, the virus can cause damage to blood and lymph vessels and lead to dengue hemorrhagic fever, which is marked by difficulty breathing, bruising and bleeding from the nose, gums or under the skin.
Scientists hypothesize that the dengue viruses evolved in nonhuman primates and jumped from these primates to humans in Africa or Southeast Asia between 500 and 1,000 years ago.

Dengue virus (DENV) belongs to the family Flaviviridae, genus Flavivirus.
It is a single-stranded positive-sense ribonucleic acid virus with 10,700 bases.
The genus Flavivirus includes other arthropod borne viruses such as yellow fever virus, West Nile virus, Zika virus, tick-borne encephalitis virus.
Dengue fever is mainly spread by the bite of infected Aedes mosquitoes, which includes A. aegypti and A. albopictus mosquitoes.
A mosquito becomes infected when it bites a person who has dengue in his or her blood.
For people who get sick with dengue, symptoms can be mild or severe.
Severe dengue can be life-threatening within a few hours and often requires care at a hospital.
The signs and symptoms of dengue include.
Headache.
Muscle, bone or joint pain.
Nausea.
Vomiting.
Pain behind the eyes.
Swollen glands.
Rash.
Dengue cannot be spread directly from person to person.
However, a person infected and suffering from dengue fever can infect other mosquitoes.
Humans are known to carry the infection from one country to another or from one area to another during the stage when the virus circulates and reproduces in the blood system.
