How to protect yourself against malaria

The right plan depends on the exact destination, season, accommodation, length and style of travel, medical history, pregnancy status and current medicines. No preventive tablet replaces bite precautions.

Malaria spreads through bites from infected mosquitoes. Repellent, covered clothing, screened or air-conditioned rooms and an intact insecticide-treated bed net reduce opportunities for bites. Preventive tablets act inside the body and must match the malaria risk and resistance pattern at the destination.

Preventive medicine lowers risk but cannot exclude infection. Malaria commonly presents with fever and may also cause chills, sweats, headache, muscle aches, nausea or marked weakness; symptoms can resemble other infections.

Arrange a travel health consultation early enough to discuss your route and begin the selected medicine on schedule. Take each dose exactly as prescribed and continue for the instructed period after leaving the risk area. If vomiting follows a dose or doses are missed, seek advice rather than doubling up without guidance.

Pack sufficient medicine in its labelled container, along with repellent and clothing that covers exposed skin. Check for interactions with regular medicines and mention kidney or liver problems, mental health history, seizures, pregnancy, breastfeeding and allergies when prophylaxis is chosen.

Fever during travel in a malaria-risk area or after returning needs urgent medical assessment, even if preventive tablets were taken. Tell the clinician every country and region visited, travel dates, prophylaxis used and whether any doses were missed.

Go to emergency care for confusion, collapse, seizures, difficulty breathing, severe weakness, repeated vomiting or inability to drink. Malaria is confirmed with blood testing; symptoms alone cannot reliably distinguish it from other causes of fever.

Ask which tablets fit your itinerary, when to start and stop them, what side effects require a change, and what to do after a missed or vomited dose. Confirm which warning symptoms should prompt testing after you return.
