The United States is at risk of losing its measles elimination status, which it has held since 2000, as the Pan American Health Organization (PAHO) reviews its measles status. The review comes amid the worst measles outbreak in the US in nearly 30 years, with over 5,000 cases reported in 2026. The PAHO's Regional Monitoring and Re-Verification Commission will assess epidemiological data and vaccination coverage to determine if the US has experienced uninterrupted measles transmission for at least 12 months. The US, along with Mexico, Guatemala, Peru, and Bolivia, is at risk of losing its elimination status. The final decision will be made by PAHO Director Jarbas Barbosa and is expected early next week.
