The correct answer is Trypanosoma brucei.Key Points

  • Sleeping sickness is caused by the microscopic parasite Trypanosoma brucei.
  • The disease is transmitted to humans through the bite of infected tsetse flies, which are found in sub-Saharan Africa.
  • If left untreated, sleeping sickness can cause serious neurological damage and eventually lead to death.
