When to see a doctor

See a doctor

See a doctor if you have a sudden high fever with severe headache, pain behind the eyes, body and joint aches, or a rash, especially during or after the monsoon or in a dengue area. A blood test can confirm it, and staying well-hydrated matters.

Get care urgently

Get emergency care right away if, usually as the fever drops, you have severe belly pain, repeated vomiting, bleeding from the gums or nose, blood in vomit or stool, black stools, cold clammy skin, restlessness, or drowsiness. These are dengue warning signs that can become life-threatening.
