Long Island Records Second Measles Case as Health Officials Urge Vaccination

Nassau County health officials confirmed a second case of measles on Long Island on October 18, 2026, raising fresh public health concern about vaccination rates in the region. Potential exposures occurred on October 8 at multiple locations in the communities of New Hyde Park, Woodbury and Great Neck. The confirmation followed a first Long Island measles case reported earlier in October. Health officials called on all residents, particularly parents of young children, to verify their vaccination status and ensure they have received the measles-mumps-rubella (MMR) vaccine. Anyone who visited the named locations on October 8 was advised to monitor for measles symptoms — including fever, cough and rash — for up to 21 days after the potential exposure date. The cases emerged against the backdrop of a broader New York measles outbreak that had previously prompted Governor Kathy Hochul to declare a state disaster emergency. Health authorities stressed that measles is highly contagious but entirely preventable through immunisation.
