Measles cases have reached a 35-year high

Measles cases in the U.S. have reached a 35-year high, surpassing 2025 totals with 2,318 confirmed cases as of July 23, 2026, affecting 44 states and D.C. Declining vaccination rates below the 95% threshold in most states, including South Carolina, Utah, Texas, Virginia, and Pennsylvania, have contributed to the outbreak, with the Pan American Health Organization considering revoking the U.S.'s measles elimination status.
