Cat Scratch Disease In Medellin, Colombia

Cat scratch disease (CSD) is the most common zoonosis transmitted by household animals. There is limited data on the epidemiology and clinical presentation of this disease in Colombia. The typical presentation includes subacute or chronic lymph node infection following inoculation of Bartonella henselae bacilli through a cat scratch. Cats have a B. henselae seroprevalence as high as 90%. Here, we report the case of a preschool boy from a rural area of Antioquia, Colombia, who presented with chronic lymphadenopathy in the right axilla. Other important infectious etiologies were ruled out, and confirmation was made with the Warthin Starry stain of a lymph node biopsy. We also discuss the most important aspects of the diagnosis, treatment and prevention of the disease.
