A child in Lewis County has died from measles, marking the first measles-associated death in New York State in more than three decades.

The New York State Department of Health and Lewis County Public Health announced the death in a joint statement on Nov. 2. Officials did not release the child's name or age.

"This is New York's first measles-related death in 30 years," Gov. Kathy Hochul said in a statement, as first reported by News 12 Westchester.

The death underscores a growing outbreak that has already prompted Hochul to declare a statewide disaster emergency on Oct. 5.

178 cases and climbing

As of Oct. 24, state health officials reported 178 measles cases across New York in 2026, according to Spectrum News. All but eight were upstate. Lewis County alone had 15 cases, all among unvaccinated people, Syracuse.com reported.

Nationally, the Centers for Disease Control and Prevention counted 4,852 confirmed measles cases across 47 jurisdictions as of Oct. 29. Neighboring Pennsylvania has reported more than 1,000 cases and five deaths, according to ABC News.

Vaccination rates slipping

The CDC says at least 95% of a community must be vaccinated for herd immunity to protect those who cannot be immunized. Nationally, kindergarten measles-mumps-rubella (MMR) vaccination coverage has dropped from 95.2% during the 2019–2020 school year to 92.4% in 2025–2026, leaving roughly 280,000 kindergartners at risk, according to the CDC.

The agency warned that local vaccination rates can vary widely. "Pockets of unvaccinated people can exist in states with high vaccination coverage," the CDC stated. "When measles gets into communities of unvaccinated people … outbreaks can occur."

Two doses of the MMR vaccine are about 97% effective at preventing measles. One dose is about 93% effective, according to the New York State Department of Health.

What the disaster order does

Hochul's Oct. 5 executive order, which was set to run through Nov. 4, expanded who can give MMR shots. Pharmacists can now vaccinate children as young as 2.

Paramedics, advanced emergency medical technicians and midwives can also administer the vaccine under the order.

As of Oct. 3, the executive order cited 108 confirmed measles cases among New York residents in 2026, with 92 of those reported since July 15 among under-immunized rural communities across 18 counties.

What residents should know

Measles spreads through the air and is one of the most contagious diseases. Up to 90% of non-immune people who are exposed will get infected, according to the state health department.

A person with measles can pass it to others four days before a rash appears through four days after.

Complications can include pneumonia, brain swelling and death. Children should receive their first MMR shot between 12 and 15 months old, with a second dose usually given between ages 4 and 6, according to the state health department.

Residents who believe they may have been exposed should contact their health care provider or local health department.
