"People don't take their antimalarial drugs when they travel because they hear bad stories about the side effects and they see native people in the areas living OK without taking pills every day. The truth is, populations native to malaria-endemic areas have all passed through pretty intense natural selection for survival and have a host of genes that prevent them from dying or suffering the other worst effects. Also, most of the resistance is built up over time, this is why it's most common for children to die rather than adults.

Whatever people have heard about the side effects of the antimalarials, getting it is so much worse. I, fortunately, have never had it, but I study it as part of my work and people have told me about having it and they all say the same thing - it is so awful you can't believe you're even still alive. It comes in cycles, usually 48-hours, and each cycle is agonizing and brings you the brink of death, sometimes it takes you, sometimes is spares you for another few hours until it starts again. And there are forms that, even if you clear the infection with drugs, it still remains dormant in your system and can come back at any time. "
