African sleeping sickness is a disease which is caused by a parasite which is a protozoa known as Trypanosoma brucei. There are certain flies which get infected by this protozoan. When the infected fly bites the human, there is transmission of the diseases. The fly is native to Africa and hence, the disease is known as African sleeping sickness. 
Thus, the correct answer is 'African sleeping sickness'.
