The National Action Plan for Combating Antibiotic-Resistant Bacteria (CARB), 2020-2025, presents coordinated, strategic actions that the United States Government will take in the next five years to improve the health and wellbeing of all Americans by changing the course of antibiotic resistance. This Plan is based on the U.S. Government’s 2014 National Strategy for CARB, and builds on the first National Action Plan released in 2015 by expanding evidence-based activities that have already been shown to reduce antibiotic resistance, such as optimizing the use of antibiotics in human and animal health settings.
