Description

Reports of known blacklegged tick bites appear to be a source of confusion for some clinicians. Only 20% or so of all patients with Lyme disease were aware of the bite that caused their infection. When a tick bite history is present, it is crucial to consider the bite in the broader clinical context. This activity will help physicians distinguish between symptomatic and asymptomatic blacklegged tick bites.

Learning objectives:

  1. Distinguish between asymptomatic and symptomatic blacklegged tick bites
  2. Employ general management principles for asymptomatic and symptomatic blacklegged tick bites


Accreditation Statement

This session, When a Blacklegged Tick Bite Is More Than a Bite, is approved for 0.25 enduring AAFP Prescribed credit.

The AAFP has reviewed VectorWise CME, and deemed it acceptable for AAFP credit. Term of approval is from 05/15/2025 to 05/14/2026. Physicians should claim only the credit commensurate with the extent of their participation in the activity.

AAFP Prescribed credit is accepted by the American Medical Association as equivalent to AMA PRA Category 1 credit(s)™ toward the AMA Physician’s Recognition Award. When applying for the AMA PRA, Prescribed credit earned must be reported as Prescribed, not as Category 1.
