Sleeping Sickness is a tropical, parasitic disease caused by the Trypanasoma brucei parasite carried by the Tsetse fly. This disease is native to the African Continent. Sleeping sickness is also known as African Trypanosomiasis and affects rural areas more.

The Tsetse fly bite presents in the form of a red sore, and increases to fevers, muscle and joint aches, lymph gland swelling, irritation and headaches. 

What is Sleeping Sickness?

Sleeping Sickness is a parasitic or tropical disease. This disease should be treated properly otherwise it can be very dangerous. This disease spreads through the bite of Tsetse fly.

  • The infection spreads throughout the body through the blood when Tsetse Fly bites.
  • The parasites can be transmitted from mother to child as it can transfer through placenta.
  • It can be infected through contaminated needles.
  • It only spreads by the bite of an infected Tsetse fly as this disease is not contagious.

  • People should use repellents or fly traps.
  • Correct guidance of medicine should be taken.

Things to Remember

  • Sleeping sickness is a disease caused by the Tsetse fly. It is a tropical illness, native to the African Continent. 
  • The disease is caused by two parasites  named Trypanosoma brucie gambiense and Trypanosoma brucie rhodesiense. They are present in the Tsetse fly. 
  • The major symptoms of Sleeping Sickness are: sores, fever, body aches, swelling etc. In advanced stages, the symptoms start affecting the central nervous system and victims can experience seizures, changes in personality, restricted bodily movement, etc. 
  • Sleeping Sickness should be treated immediately even when no symptoms are apparent. Maintaining general hygiene and cleanliness are recommended methods of prevention.
