Malaria is widespread in the Central Highlands and some parts of the Mekong Delta. The best protection against malaria is to avoid being bitten in the first place. Check with your physician about taking a course of anti-malarials. If it is considered necessary given your itinerary, you might need to begin before your trip and continue for a time after you return. But if you are not traveling to the Central Highlands nor going on overnight treks in the mountain region of Sapa, no anti-malarial drugs are needed.
