Pennsylvania has confirmed its first two measles-associated deaths in 35 years amid a nationwide resurgence. The tragic cases in unvaccinated individuals underscore the urgent need for MMR vaccination.
Harrisburg, PA – August 26, 2026 – Pennsylvania has reached a somber milestone this week, confirming its first two measles-associated deaths in 35 years, both occurring on August 25, 2026. This tragic news underscores a growing public health crisis as the highly contagious disease continues its alarming resurgence across the Commonwealth and nationwide. The two unvaccinated individuals, residents of Lancaster County, highlight the severe risks posed by measles, a disease once considered eliminated in the United States.
The Pennsylvania Department of Health (DOH) announced the deaths on Tuesday, August 25, stressing the critical importance of vaccination in preventing severe illness and fatality from measles. “My deepest sympathies are with the loved ones who are facing this unimaginable loss,” said Pennsylvania Secretary of Health Dr. Debra Bogen. She emphasized that because measles was largely eliminated for decades, many people are not familiar with its potential severity. As of Wednesday morning, August 26, 2026, Pennsylvania has reported nearly 400 confirmed measles cases across 28 counties this year, with 86 cases emerging in the last week alone. This places Pennsylvania with the third-highest tally nationwide, behind South Carolina's 670 cases and Utah's 526, according to the Centers for Disease Control and Prevention (CDC).
The deaths serve as a stark reminder that measles, though preventable, can have devastating consequences. This blog post delves into the current measles situation, the dangers of the disease, the critical role of vaccination, and essential public health recommendations to protect individuals and communities.
Measles, also known as rubeola, is a highly contagious respiratory disease caused by a virus that infects the lungs and spreads easily through the air when an infected person breathes, coughs, or sneezes. Symptoms include a high fever, cough, runny nose, red watery eyes, and a characteristic rash that starts on the head or face and spreads downward. The virus can remain in the air and on surfaces for up to two hours after an infected person leaves the area, making it incredibly easy to transmit.
An individual with measles can spread the virus to others for four days before the rash appears and for four days after it begins. It is so highly contagious that approximately 90% of unvaccinated people exposed to the virus will develop an infection. While often thought of as a childhood illness, measles can affect anyone and lead to severe complications, hospitalization, and even death.
On August 25, 2026, the Pennsylvania Department of Health confirmed the state's first two measles-associated deaths in 35 years. Both individuals were unvaccinated residents of Lancaster County, which has been identified as a significant epicenter of the current outbreak, accounting for nearly half of the state's total cases.
This tragic development follows a concerning surge in measles cases across Pennsylvania throughout 2026. In 2024, the state reported only six cases, which increased to 16 cases in all of 2025. However, as of August 26, 2026, the number has dramatically escalated to 393 confirmed cases across 28 of Pennsylvania's 67 counties, with 86 new cases reported in just the last week. Of those infected, nearly 20% (70 people) have required hospitalization.
The severity of the situation prompted Governor Josh Shapiro and Health Secretary Dr. Debra Bogen to hold a news conference, emphasizing the need for urgent action. Dr. Bogen highlighted that measles was largely eliminated in the Commonwealth for over three decades, leading to a lack of public familiarity with its potential dangers.
The tragic deaths in Pennsylvania are not an isolated incident but reflect a worrying global and national trend of measles resurgence. Despite the United States declaring measles eliminated in 2000, imported cases and declining vaccination rates have paved the way for new outbreaks.
National and Global Statistics (as of August 2026):
The CDC reported 2,777 confirmed measles cases in the United States as of August 20, 2026, across 47 jurisdictions. This represents a significant increase compared to 2,289 confirmed cases in all of 2025 and only 285 cases in 2024. The current year's caseload is the highest since the disease was eliminated in 2000, with over 90% of cases being outbreak-associated. Nationally, measles cases are at their highest levels in 35 years.
Globally, the situation is equally concerning. The World Health Organization (WHO) and CDC estimated 10.3 million cases worldwide in 2023, a 20% increase from 2022. In 2024, global cases were estimated at 11 million, an 8% increase compared to pre-pandemic levels in 2019, with 95,000 deaths recorded globally.
Factors Contributing to the Resurgence:
Several interconnected factors are driving this alarming comeback:
Measles is not just a rash; it's a serious illness with potentially severe and life-threatening complications, especially for vulnerable populations such as infants, young children, pregnant women, and individuals with weakened immune systems.
Here's why measles is particularly dangerous:
The Measles, Mumps, and Rubella (MMR) vaccine is the most effective tool we have to prevent measles and its severe complications.
In response to the current outbreak and tragic deaths, public health officials are intensifying efforts to contain the spread of measles and urge increased vaccination.
Pennsylvania Secretary of Health Dr. Debra Bogen stressed the safety and effectiveness of the MMR vaccine, stating, "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." The American Academy of Pediatrics (AAP) President, Andrew Racine, M.D., Ph.D., echoed this sentiment, lamenting the preventable deaths and calling on leaders to encourage MMR vaccination to stop the spread.
The Pennsylvania Department of Health is urging the public to report any potential measles exposure and advises individuals to check their vaccination status. They recommend that anyone due for vaccination make arrangements to receive it from their medical provider.
Key Recommendations from Public Health Authorities:
The tragic measles deaths in Pennsylvania serve as a grave reminder that vaccine-preventable diseases are not a relic of the past. The return of measles, fueled by declining vaccination rates and rampant misinformation, poses a significant threat to public health. By ensuring high vaccination coverage, we not only protect ourselves but also the most vulnerable members of our communities who cannot be vaccinated, such as infants and immunocompromised individuals.
Public health is a collective responsibility. Let us heed the warnings from health officials, prioritize vaccination, and work together to safeguard our communities against this serious, yet preventable, disease.
Measles cases are increasing primarily due to a decline in vaccination rates, particularly for the MMR vaccine, which creates "pockets of susceptibility" where the virus can spread. This decline is often linked to vaccine hesitancy fueled by misinformation and disruptions to routine immunization programs during and after the COVID-19 pandemic. Increased international travel also contributes to importing cases into communities with low immunity.
The MMR (Measles, Mumps, Rubella) vaccine is highly effective. Two doses are 97% effective at preventing measles, and one dose is 93% effective. The CDC recommends two doses for children: the first at 12-15 months and the second at 4-6 years. Adults without evidence of immunity should receive at least one dose, with two doses recommended for those at higher risk, such as healthcare workers, college students, and international travelers.
Measles can lead to severe complications, especially in young children, pregnant women, and immunocompromised individuals. About 1 in 5 unvaccinated people with measles are hospitalized. Serious complications include pneumonia (a lung infection), encephalitis (brain swelling that can cause brain damage or seizures), and ear infections that can result in permanent hearing loss. In rare but tragic cases, measles can be fatal, with an estimated one to three deaths per 1,000 cases.
If you suspect you've been exposed to measles or are experiencing symptoms such as fever, cough, runny nose, red watery eyes, and a rash, it is crucial to contact your healthcare provider immediately. Do not go directly to a healthcare facility without calling ahead; this allows the facility to take necessary precautions to prevent further transmission to other patients and staff. Public health authorities can also provide guidance on testing, isolation, and post-exposure prophylaxis.
