Pennsylvania Reports First Measles Deaths in 35 Years Among Unvaccinated Individuals

Measles Outbreak Reaches 393 Cases Across 28 Counties

The Pennsylvania Department of Health reported that the two individuals who died were Lancaster County residents who had not received the measles vaccine. To protect family privacy, health officials have declined to release any additional identifying details regarding the patients, as noted by the Pennsylvania Department of Health. The deaths occur amid a broader statewide surge. State health authorities have confirmed 393 measles cases across 28 counties throughout the commonwealth in 2026, according to data from the Pennsylvania Department of Health. Secretary of Health Dr. Debra Bogen addressed the ongoing transmission. My deepest sympathies are with the loved ones who are facing this unimaginable loss, Dr. Bogen said, according to the Pennsylvania Department of Health. Because measles was largely eliminated in the Commonwealth for more than three decades, people are not familiar with this disease and don’t fully understand the potential severity of the illness.

Public Health Guidance and Vaccination Protection

State health officials emphasize that vaccination remains the primary defense against infection. According to the Pennsylvania Department of Health, the measles, mumps, and rubella vaccine is administered over two doses to build an immune response that provides 97% lifetime protection. We want to ensure every Pennsylvanian has the information they need to protect themselves, their loved ones and their communities, Dr. Bogen stated, according to the Pennsylvania Department of Health. As a physician, I want to make sure that people understand that the MMR vaccine is safe and provides the best protection we have against measles. Health agencies note that measles is a highly contagious airborne virus. It spreads when an infected person breathes, coughs, or sneezes, and the pathogen can linger in the air and on surfaces for up to two hours after an infected individual leaves a space, according to the Pennsylvania Department of Health. Clinical complications affect a significant portion of patients. Nearly 20% of people who contract measles require hospitalization, and the virus can trigger severe short- and long-term health problems such as pneumonia and brain swelling, as reported by the Pennsylvania Department of Health. While fatalities are rare, occurring in one to three patients per 1,000 cases, the illness can be deadly without proper protection or supportive care.

Recognizing Early Symptoms and Seeking Care

Early symptoms typically appear 7 to 21 days after exposure and often mirror other respiratory viral infections. According to the Pennsylvania Department of Health, warning signs include a fever, cough, runny nose, and red, watery eyes known as conjunctivitis. A characteristic measles rash develops a few days after the initial symptoms, beginning on the head and spreading downward across the body. Because the early presentation resembles common respiratory illnesses, health officials urge anyone who develops these symptoms or suspects exposure to contact a healthcare provider promptly. Pennsylvanians who believe they have been exposed and are experiencing symptoms can contact their healthcare provider or reach the Department of Health toll-free hotline at 877-PA-HEALTH (877-724-3258), according to the agency.
