Intestinal parasites and malaria are two of the major reasons it is so difficult for developing countries to get on their feet.
When you think about how many people are suffering from these illnesses, which cause weakness and slow people down even in their mild forms, it's a wonder any work can get done at all.
That's one of the reasons major charities like the Bill Gates foundation and others are trying to start targeting diseases like this and completely eliminate them.
It's not just the human suffering, although that is a good enough reason.
It's also that intestine parasites contribute to economic poverty for the whole region.
