Dengue fever: warning signs and when to see a doctor

Dengue usually starts with high fever, headache, pain behind the eyes and body ache. Many people recover at home within a week.

Go to a hospital the same day if you see

  • Severe stomach pain or repeated vomiting
  • Bleeding from the gums or nose, or blood in vomit or stool
  • Very weak, restless or drowsy
  • Cold hands and feet, or very little urine

These signs often appear when the fever starts to go down, around day 3 to 7. Do not wait.

At home

  • Drink plenty of fluids: water, oral saline, soup, fresh juice
  • Use paracetamol for fever, as advised by a doctor
  • Avoid aspirin and ibuprofen unless a doctor tells you to take them

Which doctor to see

A medicine specialist treats dengue in adults. For children, see a pediatrician.
