Tick-Borne Infections

• Tick-borne infections are common during the summer months in many areas of the US; prevalence of specific diseases depends on the local population of vector ticks and animal reservoirs.

• Coinfection with multiple tick-borne infections can occur and should be considered when patients present with overlapping syndromes (e.g., Lyme disease with cytopenias).

• Risk should be assessed by outdoor activity in endemic regions rather than the report of a tick bite, which often goes unnoticed.
