Remember to take your antimalarials, especially if you’re heading to rural areas or backwaters such as those in luscious, green Kerala. However, even large urban areas are prone to mosquitoes. Visit a travel medicine clinic at least two months before you leave to learn what drugs and precautions you should take. Most will advise you to take the antimalarial at the same time each day and with food. Do not, however, pop the little orange tab while sitting at a beachfront bar in Chennai. Not only does this look suspicious (and will get you a tap on the shoulder from security), but taking it without food has been known to make people vomit. So pack a few protein bars.
