The Centers for Disease Control and Prevention (CDC) reports 1,792 confirmed measles cases across 37 U.S. jurisdictions as of April 23, 2026, with 93% outbreak-associated amid 22 new outbreaks this year, mainly in South Carolina, Utah, Texas, and Arizona. Nearly 92% of patients were unvaccinated or of unknown status, reflecting pockets of low MMR coverage that fuel transmission in close-knit communities. Weekly cases by rash onset have slowed markedly—to seven for the week starting April 19—continuing a downward trend from March peaks. The next CDC update, typically weekly on Thursdays, will likely incorporate late-April reports with reporting lags, determining the precise April 30 tally and market resolution.
