Tick Borne Illness Tick-borne disease surveillance studies have shown increasing prevalence, transmission, and disease burden over the last decade. Tick-borne illnesses remain a public health threat and the true incidence remains unknown and is thought to be underrepresented. Although Lyme Disease is the most frequently reported tick-borne disease in the United States, the incidence of four other tick-borne diseases is noted to be increasing in the United States:
  1. Anaplasmosis (Nov 3rd, 2020)
  2. Ehrlichiosis (Nov 4th, 2020)
  3. Rocky Mountain Spotted Fever (Nov 5th, 2020)
  4. Babesiosis (Nov 6th, 2020)
In this five-part post, we will review the salient features of these other emerging tick-borne illnesses to increase recognition of these disease entities. This overview will serve to lay a foundation and summarize shared features of tick-borne illnesses prior to diving into each specific disease.
