01 · Know
What is Dengue (Dengue Fever)?
Dengue fever is a viral infection spread by mosquitoes, common in tropical and subtropical regions, causing symptoms like high fever, severe headache, muscle and joint pain, and a rash. Most cases are uncomfortable but resolve within about a week with rest and supportive care.
A small proportion of cases can progress to a more severe form of the illness, which needs prompt hospital treatment, so it's important to know the warning signs, especially if travelling to or returning from an affected area.
02 · Understand
Clinical context
There is no specific antiviral treatment for dengue
Treatment for dengue fever focuses on supportive care — rest, fluids, and appropriate pain relief — since there is no specific antiviral medication, which is why prevention through mosquito bite avoidance is so important.
03 · Act
When to Seek Medical Advice
- 1You develop fever and severe headache, muscle pain, or a rash after travelling to an area with dengue transmission
- 2Symptoms are worsening rather than improving after the first few days
- 3You notice any warning signs of severe dengue, listed above — seek emergency care for these
04 · Prevent & manage
Practical steps
Avoid Ibuprofen and Aspirin if Dengue Is Suspected
These medications can increase bleeding risk in dengue fever — use paracetamol instead for fever and pain relief unless a doctor has advised otherwise.
- 1Rest and stay well hydrated.This supports recovery during the acute illness.
- 2Use paracetamol, not ibuprofen or aspirin, for fever and pain.This reduces the risk of bleeding complications associated with dengue.
- 3Monitor for warning signs of severe dengue.These typically appear as the fever starts to come down, a few days into the illness.
- 4Use mosquito bite prevention while travelling in affected areas.Repellent, covering exposed skin, and mosquito nets all reduce the risk of infection.
- 5Seek medical advice promptly if you develop symptoms after travel.Mention your travel history clearly, as this helps guide appropriate testing and care.

BarnMD Bottom Line
Dengue fever is usually a self-limiting illness managed with rest and supportive care, though a small number of cases need prompt hospital treatment.
Avoid ibuprofen and aspirin if dengue is suspected, and seek prompt care for any warning signs of more severe illness.
