United States measles cases reach highest level since 1991

The United States is experiencing a significant surge in measles, with the CDC reporting 2,566 confirmed cases in 2026. This represents the highest annual total since 1991. The disease has been documented in 45 states, the District of Columbia, and New York City. Approximately 93% of the cases involve unvaccinated individuals or those with unknown vaccination status.

While there have been 38 reported outbreaks this year, there have been no confirmed deaths in 2026, a decrease from the three deaths recorded in 2025. However, 169 hospitalizations have already been reported.

Localized outbreaks are being investigated across several regions. In Wisconsin, health officials are tracking an outbreak of 15 cases in southwestern counties. In Kentucky, a confirmed case in Christian County has prompted concerns of a wider outbreak following contact with an out-of-state visitor. Additionally, Tioga County is investigating a single confirmed case in an unvaccinated resident.
