National and Regional Context
The Centers for Disease Control and Prevention (CDC) reported 4,588 measles cases across the United States in 2026 as of late October, which is more than double the total for 2025. The CDC has confirmed three measles-associated deaths in the U.S. this year, though state health departments have reported higher figures. For example, Pennsylvania health officials reported six deaths this year.
In neighboring Pennsylvania, the Pennsylvania Health Department reported 1,433 cases as of Monday, including 269 hospitalizations. The CDC also reported large outbreaks in South Carolina and Utah, with both states reporting more than 500 cases.
Following a formal request from the state, the Department of Health and Human Services (HHS) stated that the CDC has deployed experts to New York to assist with the outbreak response. A spokesperson for HHS said, “Following New York’s formal request for an Epi-Aid, CDC deployed epidemiologists and other experts to work alongside state health officials on the ground, providing surveillance, data analysis, strategic planning, and other outbreak response support.”
