Tackling sleeping sickness in Africa
Sleeping sickness, spread by tsetse fly, is rife in Africa, threatening over 60 million people in 36 countries. Without treatment, the disease is fatal. There have been three severe epidemics of sleeping sickness in Africa over the last century, with the last one beginning in 1970 and still in progress. Every year, sleeping sickness and nagana – a similar disease afflicting livestock – kills 30,000 people and two million cattle.
