Measles cases are increasing in Pennsylvania, which has surpassed 1,000 confirmed cases, prompting New York to declare a state disaster emergency due to its own rise in infections. The Pennsylvania Department of Health reported on Monday that there are now 1,004 confirmed measles cases across 39 counties in 2026, with 27 new cases reported since October 2. The state has recorded 198 hospitalizations and five measles-associated deaths this year, with only four confirmed cases, less than 1%, occurring among vaccinated individuals.
In response to the outbreak, Pennsylvania is working to improve access to the measles, mumps, and rubella (MMR) vaccine. More than 53,000 doses of the MMR vaccine were administered statewide in September, which is more than double the typical monthly amount, according to the Department of Health. Officials state that two doses of the MMR vaccine provide 97% protection against measles and are urging residents to ensure their vaccinations are current. The state's measles information page offers details on vaccination locations and the latest outbreak data.
In New York, Governor Kathy Hochul declared a state disaster emergency on Monday as measles cases continue to rise. This emergency order expands the pool of healthcare professionals authorized to administer vaccines and facilitates additional testing measures to contain the outbreak. The New York State Department of Health is monitoring measles activity closely and collaborating with local health departments to investigate cases and provide vaccines and other protective measures. Health officials in both Pennsylvania and New York are advising residents to check their vaccination status and be aware of symptoms, as measles is highly contagious and can spread through the air when an infected person breathes, coughs, or sneezes.
