Sleeping sickness threatens millions of people in 36 countries.In 1986, it was estimated that some 70 million people lived in areas where disease transmission could take place.In 1998, almost 40 000 cases were reported, but estimates were that 300 000 cases were undiagnosed and therefore untreated.
