Symptoms Urgent signs Care Prevention FAQs

Dengue is a viral illness transmitted by infected mosquitoes. Many infections cause little or no illness, but severe dengue can be life-threatening. Early medical attention matters.

Recognise the possible symptoms

Fever and pain

Fever may occur with headache, pain behind the eyes, and muscle or joint aches.

Other symptoms

Nausea, vomiting and a rash may also occur.

Symptoms overlap with other illnesses. A clinician can assess whether dengue testing is appropriate.

These signs need immediate medical care

Seek urgent medical help if you or a family member develops:

• Severe abdominal pain or tenderness.
• Repeated or persistent vomiting.
• Bleeding from the nose or gums.
• Blood in vomit or stools.
• Extreme tiredness or restlessness.
• Rapid breathing, pale cold skin or marked weakness.

Do not wait for the fever to return before seeking help.

Suspect dengue? Get assessed.

Contact a healthcare professional, rest and drink fluids. Severe symptoms require urgent care.

Medicine caution: Avoid aspirin and ibuprofen for suspected dengue because they can increase bleeding risk. Ask a clinician about appropriate fever relief.

Reduce mosquito bites and breeding sites

Dengue-spreading mosquitoes are active during the day. Protection should extend beyond bedtime.

• Use a suitable insect repellent according to its label.
• Wear clothing that covers exposed skin.
• Use window screens and nets when sleeping during the day.
• Empty and scrub water-holding containers weekly.
• Cover water storage and remove items collecting water.
