  • Aedes aegepti  mosquito bites during daylight hours.
  • Person develops symptoms 3-14 days after the infective bite.
  • Patients who are already infected with the dengue virus can transmit the infection to other via Aedes mosquitoes during 4-5 days of onset of symptoms.

Dengue fever starts with sudden onset of fever, followed by severe headache, pain behind the eyes, muscle and joint pain, and rash.

Dengue haemorrhagic fever has an acute onset of fever followed by abdominal pain, vomiting, bleeding.  A small proportion of cases may show fatal disease as dengue shock syndrome.

There are no specific antiviral medicines for dengue. Early clinical diagnosis by physician and proper clinical management lowers the fatality rates below1%. Use of analgesics (pain reliever) with paracetamol, promoting patient to drink plenty of fluids and rest are important.

Use of acetylsalicylic acid (e.g. aspirin) and non steroidal anti-inflammatory drugs (e.g. Ibuprofen) is not recommended.
