In my experience from living in Tanzania, malaria is way down in Africa. Almost everyone said that true malaria isn't very common. I started a school there and none of the 200 kids there got malaria over the 4 year span of the school's existence.

I think the statistics about it might be overestimating since people constantly say they have malaria, but rarely if ever have it. It means just sick colloquially in Swahili.
