DENGUE FEVER

DENGUE FEVER

  • Dengue fever is a painful mosquito-borne viral disease that can lead to a severe flu-like illness.
  • This disease is spread by the mosquitoes Aedes aegypti and Aedes albopictus that are found throughout the world.
  • The mosquito thrives during the rainy season but can breed in water-filled cans and flower pots year-round.
  • It is the most important mosquito infected disease affecting humans worldwide.
  • According to the World Health Organization, an estimated 390 million dengue fever cases are recorded worldwide each year resulting in about 22,000 deaths mostly among children.
  • Dengue fever has its prevalence in tropics and subtropics region of the world with the highest risk occurring in Africa, the Pacific Islands, Mexico, Asia, and Taiwan.
  • In rare cases, the disease can progress into dengue hemorrhagic fever or dengue shock syndrome which are life-threatening.
  • In several Asian countries, dengue hemorrhagic fever has become the most prevalent cause of disease and death, especially in children.
  • Dengue fever doesn’t spread from person to person, the only mode of transmission is bites from infected mosquitoes.
  • The mosquito thrives during the rainy season but can breed in water-filled cans and flower pots year-round.
  • It is also referred to as breakbone fever or dandy fever.

CAUSES

  • The dengue fever is caused by four dengue viruses that are spread by Aedes aegypti, a species of mosquito and more rarely by the Aedes albopictus, Aedes polynnesiensis, and Aedes scutellaris
  • When a mosquito bites an infected person, the virus enters the mosquito.
  • The virus is then spread when the infected mosquito bites another human.
  • Living or traveling to tropical or sub-tropical areas increases your risk of exposure to the virus causing dengue fever.

TREATMENT

Dengue fever is a viral infection and does not have a specific cure or treatment. Interventions can help  depending on how severe the disease is.

The mild dengue fever can be treated by:

Keeping the body hydrated.

Painkillers such as paracetamol to help lower fever and ease the pain.

Painkillers such as aspirin, ibuprofen should be avoided as they can increase bleeding complications.
