I've had malaria, and it sucks. Luckily it wasn't brain malaria, which is highly fatal. There are multiple drugs available to prevent malaria. Atabrine, chloroquinine, doxycline. Something is available that will work for you without side effects. Get it, take it, and sleep comfortably knowing you're protected. Or, catch malaria, spend two weeks in the hospital vomiting and crapping until you'd almost rather die, and then two weeks getting your strength back. Oh, and by the way, malaria can then re-occur occasionally, although with lessening severity.
Take the pills. Malaria really sucks!
