Abstract

Baloxavir marboxil is approved for influenza treatment and post-exposure prophylaxis (PEP). There are limited real-world examples of its use in influenza outbreaks. Here, we describe the use of baloxavir marboxil as PEP to halt an influenza outbreak among a college sports team during the 2024-2025 influenza season.
