What is dengue?

A viral infection spread by Aedes mosquitoes. It's common in Malaysia all year round.

What are the symptoms?

• Sudden high fever

• Severe headache and pain behind the eyes

• Body and joint aches

• Nausea, vomiting or rash

When is it dangerous?

Often on days 3–7, just as the fever goes down. Go to a clinic or hospital immediately if there's:

• Persistent vomiting or severe tummy pain

• Bleeding gums, nose or blood in stool

• Drowsiness or cold, clammy hands

• Very little urine

How is it tested?

A simple blood test (full blood count and dengue test) at the clinic.

What can I take for fever?

Paracetamol only. Avoid ibuprofen, aspirin and mefenamic acid, which raise the risk of bleeding. Drink plenty of fluids.

How do I prevent it?

Clear standing water every week, use mosquito repellent and cover up.
