A child in upstate New York has died from measles — the state's first measles death in over 30 years — as the US faces its worst measles year since 1991. With nearly 4,900 confirmed cases nationwide and deaths reported across Pennsylvania and New York, declining vaccination rates and inconsistent federal death-counting practices are fueling the crisis.
A child in Lewis County, New York, has died from measles — the state's first measles fatality in more than three decades — as the US grapples with a historic resurgence of the disease. New York Governor Kathy Hochul had already declared a statewide emergency last month, and the state has confirmed 178 cases in 2026 alone. The death adds to a growing national toll that includes at least five confirmed measles deaths in Pennsylvania, where the largest active outbreak has logged over 1,400 cases.
Nationally, 2026 is the worst year for measles since 1991, with the CDC confirming 4,852 cases across 45 states and Washington, D.C. — more than double the 2,289 cases reported in all of 2025. Nearly all cases (96%) are tied to active outbreaks, and experts warn the true number is likely far higher since many people never seek medical care. The CDC is also under scrutiny for undercounting deaths, listing only three US measles fatalities while states report significantly more — a discrepancy the agency says it is working to resolve by standardizing death-counting definitions with state epidemiologists.
By the Numbers:
Why it matters: Measles was declared eliminated in the US in 2000, but falling vaccination rates — driven by misinformation and rising exemptions — have created dangerous gaps in herd immunity. With winter approaching, experts warn the outbreak could worsen significantly, and inconsistent federal death reporting is making it harder to grasp the true scale of the crisis.
