The United States is experiencing its worst measles outbreak in three decades, with over 5,000 cases reported this year alone. The Centers for Disease Control and Prevention (CDC) has confirmed 5,182 cases as of November 5, 2026, with at least eight deaths. Pennsylvania has the largest outbreak, and children and teenagers make up nearly 60% of confirmed cases. Experts warn that the US may lose its measles elimination status due to declining vaccination rates and vaccine hesitancy.
