You likely have done so, many times. For many countries malaria is so endemic that most people have had it once or more (malaria is not very lethal if you have access to the right medicines; the problem is a lot of people don't). Except for people living in places with extremely low immigration levels, it is unlikely that you'll go very long before coming across someone who have had malaria.

Yeah, right.
