Rocky Mountain spotted fever is a potentially fatal infection that comes from tick bites. It's not well understood, and there's no test to diagnose it. Rocky Mountain spotted fever generally comes on about a week after the tick bite.
Symptoms come on suddenly and include:
- Fever
- Muscle aches
- Headaches
- Vomiting
The rash starts smooth and blotchy around the wrists and ankles a few days after the other symptoms. It can become raised later. One out of ten patients never get a rash.
