Malaria

Symptoms

Signs and symptoms of malaria may include:

  • Fever
  • Chills
  • General feeling of discomfort
  • Headache
  • Nausea and vomiting
  • Diarrhea
  • Abdominal pain
  • Muscle or joint pain
  • Fatigue
  • Rapid breathing
  • Rapid heart rate
  • Cough

Some people who have malaria experience cycles of malaria "attacks." An attack usually starts with shivering and chills, followed by a high fever, followed by sweating and a return to normal temperature.

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 up to a year.

When to see a doctor

Talk to your doctor if you experience a fever while living in or after traveling to a high-risk malaria region. If you have severe symptoms, seek emergency medical attention.
