This module provides an overview of perinatal risks and outcomes related to congenital Lyme and co-infections.

Learning objectives

  1. Describe the differing perinatal outcomes in vertical transmission of Borreliosis.
  2. List tick-borne pathogens that can be perinatally transmitted to a neonate.
  3. Discuss risks to infant from perinatally-acquired Relapsing Fever Borrelia infection.

This session, Congenital Lyme & co-infections, is approved for 0.5 enduring AAFP Prescribed credits.

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.

The AAFP has reviewed One Health Medical Education for a Changing Climate and deemed it acceptable for AAFP credit. Term of approval is from 01/02/2024 to 01/01/2025. Physicians should claim only the credit commensurate with the extent of their participation in the activity.
