A malaria infection is generally characterized by recurrent attacks with the following signs and symptoms:

  • Moderate to severe shaking chills
  • High fever
  • Profuse sweating as body temperature falls

Other signs and symptoms may include:

  • Headache
  • Vomiting
  • Diarrhea

Malaria signs and symptoms typically begin within a few weeks after being bitten by an infected mosquito. However, some types of malaria parasites can lie dormant in your body for months, or even years.

When to see a doctor

Talk to your doctor if you experience a high fever while living in or after traveling to a high-risk malaria region. The parasites that cause malaria can lie dormant in your body for months. If you have severe symptoms, seek emergency medical attention.
