Measles Outbreak Sweeps Across U.S—New York Declares Disaster Emergency: Nearly 3,900 Cases Reported Nationwide, Highest Level Since 1991
By Progga News Desk:
A major measles outbreak is spreading across the United States, with nearly 3,900 confirmed cases reported nationwide so far in 2026, according to the Centers for Disease Control and Prevention (CDC).
As of October 1, the CDC had recorded 3,887 confirmed measles cases in the United States. The cases have been reported across 47 jurisdictions, including the District of Columbia, making 2026 the worst year for measles in the United States since 1991. The CDC notes that the figures are preliminary and subject to change as health departments continue to report and investigate cases.
The growing outbreak has prompted New York Gov. Kathy Hochul to declare a statewide Disaster Emergency. Hochul signed the executive order on October 5 as measles cases continued to rise, particularly in rural communities outside New York City.
As of October 3, New York had reported 108 measles cases in 2026, including 92 cases identified since July 15 in under-immunized rural communities across 18 counties. Seven cases had been reported in New York City, with the remainder occurring elsewhere in the state.
The emergency order, which is scheduled to remain in effect through November 4, expands the state’s ability to respond to the outbreak. It allows registered nurses to order measles testing and expands the authority of pharmacists to administer MMR vaccines to children as young as 2. State and local health officials are also intensifying vaccination efforts, testing, case investigations and contact tracing in affected communities.
More than 1,000 MMR vaccines have already been administered in affected rural communities, according to state officials. Health authorities are urging New Yorkers to check their vaccination records and make sure they are up to date on measles, mumps and rubella vaccinations.
Pennsylvania Outbreak Surpasses 1,000 Cases
The situation is particularly serious in neighboring Pennsylvania, where the state has experienced its largest measles outbreak in more than three decades.
As of October 5, Pennsylvania health officials had reported 1,004 measles cases, including 198 hospitalizations and five deaths. The outbreak is one of the largest contributors to the nationwide surge in measles cases.
The outbreak has been especially severe in communities with lower vaccination rates. Health officials and experts say declining vaccination coverage has contributed to the loss of the level of community protection needed to slow the spread of measles.
Declining Vaccination Rates Raise Concern
Health officials are increasingly concerned about declining childhood vaccination rates across the country.
According to the CDC, MMR vaccination coverage among U.S. kindergarten students fell from 95.2% during the 2019–2020 school year to 92.4% during the 2025–2026 school year. The CDC estimates that approximately 280,000 kindergarten students were not adequately protected during the 2025–2026 school year.
The agency says communities generally need vaccination coverage above 95% to maintain strong community immunity. When measles is introduced into communities with lower vaccination rates, outbreaks can spread rapidly.
Federal Health Officials Offer Support
The federal government has increased coordination with states experiencing significant outbreaks.
U.S. Health Secretary Robert F. Kennedy Jr. has offered federal assistance to New York, including coordination with CDC officials and additional public-health expertise if needed. Federal health officials have also deployed epidemic-assistance teams to several states, including Texas, South Carolina, Virginia, Kansas, New Mexico and Wisconsin.
Highly Contagious Disease
Measles is one of the most contagious infectious diseases known. It spreads through the air when an infected person coughs, sneezes or breathes. The virus can remain infectious in the air for extended periods, allowing it to spread rapidly in crowded or poorly vaccinated communities.
Common symptoms include high fever, cough, runny nose, red or watery eyes and a characteristic skin rash. In serious cases, measles can lead to pneumonia, encephalitis, hospitalization and death. New York health officials are urging anyone who develops fever and a rash to contact a health care provider or local health department promptly.
MMR Vaccine Remains the Key Defense
Health authorities say vaccination remains the most effective way to prevent measles and limit outbreaks.
The MMR vaccine protects against measles, mumps and rubella. Maintaining high vaccination coverage is particularly important for protecting infants, young children and people who cannot be vaccinated for medical reasons.
New York health officials are urging residents to review their vaccination records and ensure that they and their families are current on recommended MMR vaccinations.
The current resurgence is also raising broader public-health concerns. The United States has maintained measles elimination status for years, but sustained transmission and large outbreaks could threaten that status. Health officials say aggressive vaccination, rapid identification of cases, contact tracing and public awareness will be critical to containing the current outbreak.
