One Health and Streptococcus Canis in the Emergency Department: A Case of Cellulitis and Bacteremia in an Immunocompromised Patient Treated With Etanercept.

Background: One Health is a biomedical approach that aims to optimize the health of humans, animals, and the environment through interdisciplinary collaboration. Cellulitis is an infection of the dermis and subcutaneous fat that may be caused by zoonotic streptococci species.
Case Report: We report a case of cellulitis caused by Streptococcus canis in a woman who was taking Etanercept. We frame the presentation within a One Health approach and urge emergency physicians to collaborate with veterinarians in the management of patients with zoonotic diseases who are discharged home. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Pets are a source for zoonotic diseases, including resistant bacteria, that pose particular risk to immunocompromised patients. Emergency physicians often discharge patients with potential zoonotic infections such as cellulitis home without a long-term, holistic care plan, according to a One Health approach. Physicians should then collaborate with veterinarians in caring for humans and animals.
