Key points
- Wisconsin’s measles outbreak has reached a 35‑year high with 431 cases and nine hospitalizations.
- The infant’s death brings the national total of measles‑related fatalities to eight for 2026.
- Unvaccinated or unknown‑status individuals account for roughly 96% of U.S. measles cases this year.

The Wisconsin Department of Health announced Thursday that an infant has died after contracting measles, the first measles‑related death in the state since 1990.
The outbreak has produced 431 confirmed measles cases in Wisconsin so far this year – the highest tally for the state in over 35 years – and nine of those patients have required hospitalization.
State Impact
State Health Secretary Kirsten Johnson said in a press release, "It is with a heavy heart we are reporting the first death of an infant connected with a measles outbreak in Wisconsin in many years. My heart is broken for the family. Any death of a child is a tragedy and even more so when it is related to a vaccine‑preventable disease."
Across the United States, the CDC reports more than 4,800 measles cases this year, the most since 1991, with at least 96% of those infections occurring in people who are unvaccinated or whose vaccination status is unknown. The nation has recorded eight measles‑related deaths so far: six in Pennsylvania, one in New York, and the recent case in Wisconsin.
National Context
The CDC outlines early measles symptoms as cough, runny nose, fever up to 104 °F, and red, watery eyes, followed by Koplik spots in the mouth and a spreading rash. It continues to recommend two doses of the MMR vaccine – the first at 12‑15 months and the second at 4‑6 years – which together are 97% effective at preventing infection. Infants 6‑11 months in high‑risk areas may receive an early third dose.
