If you’re planning to travel the world, it’s important to know about malaria. According to LifeHacker, West Africa is the area with the highest risk of malaria transmission, and other areas of Africa, Asia, Oceania, and parts of South America can pose a malaria risk as well. Start by visiting a doctor or clinic that understands travel medicine. They’ll help you figure out how much of a risk malaria is at your destination. If they prescribe medication, then take it. Don’t skip doses, and don’t stop taking it early, either. Bring insect repellent and a mosquito net with you on your trip, and use both religiously. Remember, it’s possible to develop malaria even after returning from your trip. So for at least three months, keep an eye out for fever or flu-like symptoms, including headache, chills, and muscle weakness. Make sure to tell your doctor that you’ve been to an area with malaria. Happy travels!
