Symptoms of dengue usually begin within 2 weeks of being bitten by an infected mosquito.1
If you develop a fever or have symptoms of dengue while you’re abroad, see a local doctor or seek prompt medical care. If you’ve already returned home by the time you feel ill, see your own doctor.
Mild dengue
- Most people infected have mild or no symptoms.2
- Mild symptoms of dengue may be confused with other illnesses that cause fever, such as COVID-19 and flu.2
- Most people will recover from mild dengue after about one week.2
- If you have a fever, a common recommendation is to take paracetamol (acetaminophen) to reduce fever and manage body aches.1
- Do not take aspirin or ibuprofen; they thin the blood and may increase the risk of bleeding.1
- Rest and drink plenty of fluids.1
- Contact your doctor.1
Severe dengue3
An uncommon but potentially fatal complication, known as severe dengue, can develop 3-7 days after the illness first started.
Warning signs of severe dengue include:
- Severe stomach pain
- Persistent vomiting
- Bleeding from gums
- Feeling tired
- Rapid breathing
- Restlessness
- Blood in vomit or stool
Contracting severe dengue should be considered a medical emergency. If you develop any of these warning signs, go to a hospital immediately.
