Abstract
We describe an outbreak of Highly Pathogenic Avian Influenza (HPAI) A(H5N1) in sea lions (Otaria flavescens) of South America. More than 24,000 sea lions died in Peru, Chile, Argentina, and Uruguay between January and September 2023. The most plausible route of infection is cohabiting with or foraging on sick birds. However, there is a need to clarify the source of infection of these sea lions given that the massive wild bird mortalities registered in the Pacific Ocean do not appear to have occurred in the Atlantic.
