What should you know about endemic malaria?

Endemic means transmission continues in a location over time. Malaria parasites are spread through bites from infected mosquitoes. Illness may begin with fever, chills, sweating, headache, or muscle aches, and symptoms can be intermittent. The pattern may differ between infections, and a person may not feel ill immediately after exposure.

Diagnosis usually requires a blood test that looks for evidence of malaria parasites. A travel or residence history matters because it helps the clinician interpret symptoms and choose appropriate testing. Malaria can become severe, so suspected illness should not be managed by waiting for symptoms to pass.

Tell a clinician promptly about travel, residence, mosquito bites, and any malaria medicines taken. Take prescribed treatment exactly as directed and complete the course unless the prescriber changes it. Reduce further bites with repellent, covered skin, and suitable bed nets. Before travel, a travel health consultation can review destination risks and malaria prophylaxis; prevention depends on the region and your health history.

Seek urgent medical help for fever after visiting an endemic area, particularly with confusion, extreme weakness, breathing difficulty, repeated vomiting, fainting, or yellowing of the skin. Emergency assessment is needed if a person becomes difficult to wake or has a seizure. Explain the travel history even if the exposure was weeks earlier.

Ask which blood test is needed, whether repeat testing may be required, which warning signs to watch for, and what prevention plan fits your destination, medicines, pregnancy status, and other health conditions.
