As of April 9, 2026, the CDC confirms 1,714 measles cases in the United States this year—94% outbreak-associated across 17 incidents in states like Utah (408 cases), Texas, South Carolina, Arizona, and Florida—reflecting a sharp surge from 1,281 in early March due to low vaccination rates in undervaccinated communities and the virus's high transmissibility (R0 of 12–18). This pace exceeds 2025's 2,267 annual total, straining public health surveillance since measles elimination in 2000. With two weeks until April 30 resolution, monitor CDC's weekly case updates and MMWR reports for new confirmations from recent exposures, as reporting lags can shift final tallies amid ongoing spread.
