Symptoms
By Mayo Clinic staffA 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
- General feeling of unease and discomfort (malaise)
Other signs and symptoms include:
- Headache
- Nausea
- Vomiting
- Diarrhea
When to see a doctor
Because malaria infection often initially appears to be a flu-like illness or some other viral disease, be wary if you develop an illness with fever while living in a malaria-endemic area or within 12 months after traveling to a high-risk malaria region. See your doctor as soon as possible, and tell your doctor where you've traveled. Left untreated, a malaria infection can cause serious, potentially life-threatening health problems.
