Sleeping sickness
People get African trypanosomiasis from the tsetse fly.  Because of this, it is most common in certain areas of Africa, especially Sub-Saharan Africa, where the tsetse fly lives.  Researchers say that about 70 million people, in 36 countries, are at a high risk for getting sleeping sickness. As of 2010, sleeping sickness had caused around 9,000 deaths per year (compared to 34,000 in 1990).
