Deffinetly agree with staying off preventative medication. Be smart and use your net and cover up at night, African mosquitos are most active after sunset.
One story is that they do not like the smell of Garlic so eat plenty of that. They also don't like the smell of alchohol so that is the best excuse ever to go for a few beers.
Also recomend getting the meds for after you get it and also if you can get hold of a few self test kits and read up any info you can find on Malaria, especially when out in the middle of no where.
Remeber meds are very sensetive to heat so store them right, there is no guarantee that local available products might even work after been transported to the back of beyond or stored inproperly.
It seems inevetable to get it so good luck
