Pennsylvania has recorded its fifth measles death this year, and the state's measles outbreak is still growing. The Pennsylvania Department of Health announced on September 30, 2026 that an unvaccinated resident of Lancaster County who tested positive for measles had died. Here is what we know, why this outbreak matters, and what you can do to protect yourself and your family.
What We Know About the Fifth Measles Death in Pennsylvania
State health officials reported that the person who died was unvaccinated and lived in Lancaster County. No further details about the person have been released. The department said the death meets the official definition of a measles-associated death and has been reported to the Centers for Disease Control and Prevention (CDC).
A measles-associated death is one that occurs within 30 days of symptom onset in a person with a confirmed measles infection, unless the death was caused by something unrelated.
This is the third measles-associated death reported in Lancaster County this year. The earlier deaths in the outbreak were:
- Two infants in Lancaster County, announced in August (the first measles deaths in Pennsylvania in 35 years)
- An 18-year-old from Mifflin County
- A 40-year-old woman from Jefferson County
None of the five people had been vaccinated. The two infants were too young to receive the vaccine under current recommendations.
Pennsylvania Measles Outbreak by the Numbers
- 943 confirmed cases across 39 counties
- About 40% of cases are concentrated in Lancaster County
- Fewer than 1% of cases involved vaccinated people
- At least six babies have been born with congenital measles in the state
- More than 53,000 MMR doses were given statewide in September, over double a typical month
- 3,569 confirmed cases nationwide this year, according to the CDC, the worst year for measles in the US since 1991
Why Is There a Dispute Over the Death Count?
The CDC has so far recognized only two measles deaths nationally in 2026, while Pennsylvania reports five. Federal and state officials have publicly disagreed over how these deaths are counted. Pennsylvania says all five meet the standard definition used by public health epidemiologists and says it has reported them to the CDC. Regardless of how the deaths are classified, health experts agree on one point: measles is serious and preventable.
Is Measles Really That Dangerous?
Many people assume measles is a mild childhood illness. It isn't. Measles is one of the most contagious viruses known. It spreads through the air when an infected person coughs or sneezes, and the virus can stay in a room for up to two hours after that person leaves. Up to 9 out of 10 unvaccinated people exposed to the virus will become infected.
Deaths occur in roughly one to three of every 1,000 cases, and complications can include pneumonia, brain swelling (encephalitis), and severe dehydration. Infants, pregnant women, and people with weakened immune systems are at highest risk.
Measles Symptoms: What to Watch For
- High fever, which can reach 104°F (40°C)
- Cough, runny nose, and red, watery eyes
- Tiny white spots inside the mouth (Kop like spots)
- A red, blotchy measles rash, which typically starts on the face and spreads down the body 3 to 5 days after the first symptoms
An infected person can spread measles from about four days before the rash appears until four days after. That means people can pass it on before they know they have it.
If you suspect measles, call your doctor or clinic before going in so staff can take precautions to avoid exposing others in the waiting room.
How to Protect Yourself and Your Family
- Children: The first dose is recommended at 12 to 15 months and the second at 4 to 6 years of age.
- Adults: If you're unsure about your vaccination status, ask your doctor. Adults without evidence of immunity may need a dose.
- Travelers and those in outbreak areas: Talk to your healthcare provider about whether an early dose or booster is appropriate.
- Check your records: Your doctor or state immunization registry can confirm what you've had.
Caring for Skin During Measles Recovery
For readers who have a mild case under medical supervision, the rash and fever can leave skin dry and sensitive. Gentle care can help comfort: use lukewarm baths, a fragrance-free moisturizer, loose cotton clothing, and avoid scratching or harsh exfoliants. Skincare does not treat measles, and anyone with symptoms should follow their doctor's guidance.
