What should you know about Gates Foundation malaria?

Malaria parasites enter the bloodstream through the bite of an infected mosquito. Illness may begin with fever, chills, sweating, headache, tiredness, or muscle aches, and symptoms can appear after a person has returned from a risk area. Malaria can become severe because it affects blood cells and organs, so feeling better between fever episodes does not rule it out. A fever after travel to a malaria-risk region deserves medical advice.

Tell the clinician where you travelled, when you returned, whether you took prevention medicine, and whether you recall mosquito bites. Testing may include a blood test, and treatment depends on the parasite and illness severity. Before travel, a travel health consultation can match prevention advice to the destination, season, activities, and your medical history. Malaria prophylaxis may be prescribed, alongside bite prevention such as repellent, covered clothing, and screened or netted sleeping areas.

Seek urgent medical assessment for fever or chills after travel in a malaria-risk area, particularly with confusion, breathing difficulty, repeated vomiting, extreme weakness, jaundice, collapse, or a seizure. Do not wait for symptoms to settle or rely on home treatment if malaria is possible.

Ask whether your travel route carries malaria risk, which symptoms require urgent testing, how prevention medicine should be taken, and what to do if fever develops after returning.
