Dengue Fever: Causes, Symptoms, Treatment and Prevention

Dengue Fever


Dengue is a serious and neglected tropical disease caused by the dengue virus. It’s transmitted through the bite of an Aedes mosquito infected with one of the four serotypes of the dengue virus. Dengue is prevalent throughout the world and causes millions of illnesses in tropical and subtropical countries every year.

Causes of Dengue Fever

The dengue virus is passed on to humans primarily through the bite of infected female mosquitoes; however, it can also be passed on through blood transfusions and organ transplants. The Aedes mosquito is most commonly found in urban and semi-urban areas, especially during the wet season.

Symptoms of Dengue Fever

Dengue fever typically causes mild to severe symptoms that last from several days to a week, including:

  • Fever
  • Severe headaches
  • Muscle and joint pain
  • Nausea and vomiting
  • Skin Rash

In severe cases, dengue can cause dangerous complications, including hemorrhagic fever, shock syndrome, and organ failure.

Treatment and Prevention of Dengue Fever

  • Early Diagnosis: Early diagnosis and treatment of dengue fever is important, as it can reduce the risk of complications.
  • Mosquito Control: The most important part of preventing dengue fever is controlling the population of mosquitoes that can spread the disease. There are several ways to reduce the number of Aedes mosquitoes, including eliminating areas of standing water and using insecticides.
  • Vaccine: A vaccine is available to help reduce the risk of becoming infected with dengue. The vaccine is recommended for people between the ages of 9 and 45.

Health Risks Associated with Dengue Fever

Dengue is a serious illness that can cause severe and even fatal complications, such as hemorrhagic fever, shock syndrome, and organ failure. People with preexisting medical conditions, weakened immune systems, and young children are especially at risk of life-threatening complications.
