Check anything you're experiencing to see general guidance.

This tool is for general awareness only and can't diagnose dengue or any other illness. A blood test from a doctor or clinic is the only way to confirm it — please see one if you're unwell.

Warning signs — don't wait these out

• Severe, constant pain in the belly
• Vomiting three or more times in 24 hours, or vomiting blood
• Bleeding from the nose or gums, or blood in stool
• Fast breathing or trouble breathing
• Cold, clammy skin, or sudden restlessness and confusion
• Fever that drops but the person feels worse, not better

Any of these, at any point — get to an emergency room right away.

Prevention

Break the mosquito's cycle

Dengue spreads through the Aedes mosquito, which mostly bites during the day — early morning and late afternoon are its busiest hours.

Empty standing water

Buckets, flowerpot trays, and gutters — clear them out every few days.

Use repellent by day

Apply it to exposed skin, especially in the morning and late afternoon.

Screen it up

Nets on beds and mesh screens on windows keep mosquitoes from getting in.

Cover up

Light, loose long sleeves and trousers during peak biting hours.

How it usually unfolds

The three phases of dengue

1

Febrile phase — days 1 to 3

High fever arrives suddenly, often with headache, body aches, and a flushed face. Rest and fluids matter most here.

2

Critical phase — days 4 to 6

Fever drops, which can feel like recovery — but this is when warning signs, if they appear, matter most. Watch closely.

3

Recovery phase — day 7 onward

Fever stays down and strength gradually returns, though fatigue can linger for a couple of weeks.
