Can I take a medication to prevent African trypanosomiasis?

There is neither a vaccine nor recommended drug available to prevent East or West African trypanosomiasis.

How can I prevent African trypanosomiasis and prevent other insect bites?

  1. Wear protective clothing, including long-sleeved shirts and pants. The tsetse fly can bite through thin fabrics, so clothing should be made of thick material.
  2. Wear khaki or olive colored clothing. The tsetse fly is attracted to bright colors and very dark colors.
  3. Use insect repellant. Though insect repellants have not proven effective in preventing tsetse fly bites, they are effective in preventing other insects from biting and causing illness.
  4. Use bed netting when sleeping.
  5. Inspect vehicles for tsetse flies before entering.
  6. Do not ride in the back of jeeps, pickup trucks or other open vehicles. The tsetse fly is attracted to the dust that moving vehicles and wild animals create.
  7. Avoid bushes. The tsetse fly is less active during the hottest period of the day. It rests in bushes but will bite if disturbed.
