Rocky Mountain spotted fever is a serious, generalized infection that is usually spread to people by the bite of infected ticks. The disease gets its name from the Rocky Mountain area where it was first identified.

  2. The rash might begin on the legs or arms, can include the soles of the feet or palms of the hands, and can spread rapidly to the trunk or the rest of the body.
