What should you know about malaria bites?

Malaria spreads when an infected mosquito passes parasites into the bloodstream while biting. The bite itself may look like an ordinary insect bite, or it may not be noticed. A skin mark cannot confirm or exclude malaria. The relevant clue is exposure in a place where malaria occurs followed by symptoms such as fever, chills or muscle aches.

Record where and when you travelled and whether you used repellent, bed nets or prescribed prevention medicine. Contact a clinician promptly if illness develops and explain the mosquito exposure, even if the bite has healed. A blood test may be needed. For upcoming travel, a travel health consultation can review destination-specific protection and malaria prophylaxis rather than relying on the appearance of a bite.

Seek urgent care for fever, chills or marked muscle aches during or after travel to a malaria-risk area. Go to emergency care for confusion, collapse, breathing difficulty, severe weakness or repeated vomiting. These signs need rapid assessment because malaria may become serious before the skin bite is still visible.

Ask whether your destination creates malaria risk, whether you need testing now, how long to watch for symptoms, and which prevention options fit your medicines, pregnancy status or medical conditions.
