Limiting exposure to ticks is the most effective way to reduce the likelihood of Rocky Mountain spotted fever infection.

  1. No vaccine is available to protect humans against Rocky Mountain spotted fever. The best way to avoid getting the disease is to avoid areas such as the woods or fields where ticks are found. If this is not possible, you can reduce your risk by taking these precautions:
  2. Control the tick population on your property. Keep pets tick-free. Mow grass often in yards and outside fences.
  3. During outside activities in wooded areas and around tall grass, wear long sleeves and long pants tucked into socks.
  4. Remove attached ticks immediately. Removing a tick before it has been attached for more than 4 hours greatly reduces the risk of infection.
  5. After removing the tick, thoroughly disinfect the bite site, and wash your hands.
