STEP 234: Cat-scratch Disease: Epidemiology, Etiology, and Treatment (CE: 1.0)


Cat-scratch disease (CSD) is a clinical syndrome that usually presents as self-limiting lymphadenopathy associated with a cat scratch or bite. Commonly affecting children and young adults, it has a worldwide distribution. In temperate climates, higher rates are reported in the autumn and winter, which can be attributed to the seasonal breeding of the domestic cat. This article discusses the historical overview, etiology, epidemiology, clinical presentation, diagnosis requirements, and treatment for CSD.
