Description

This module provides an overview of the history of Bartonella spp infection, from the discovery of Carrion’s disease in South America through trench fever in WWI and the etiology of cat scratch disease in HIV/AIDS epidemic.

Learning objectives

  1. Describe the medically relevant history of bartonelloses prior to the recognition of the Human Immunodeficiency Virus (HIV) epidemic in the 1980’s
  2. Describe the “rediscovery” of the genus Bartonella as a consequence of the AIDS epidemic
  3. Describe the medical history associated with the discovery of Cat Scratch Disease and the eventual identification of Bartonella henselae as the definitive causative agent.


Accreditation Statement

This session, Bartonelloses: History of a hidden pandemic, is approved for 1.0 enduring AAFP Prescribed credit.

The AAFP has reviewed One Health Medical Education for a Changing Climate, and deemed it acceptable for AAFP credit. Term of approval is from 01/01/2025 to 12/31/2025. 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.
