Pennsylvania confirms its sixth measles-associated death of 2026: the facts and the home checks

What Pennsylvania confirmed on November 4

DOH said on November 4 that an unvaccinated Jefferson County resident who tested positive for measles has died. It says the death was reported to the Centers for Disease Control and Prevention (CDC) and added to the state's measles dashboard. To protect the family's privacy, DOH "will not release any additional details that could personally identify them," so the person's age and other details have not been published.

DOH says the six people who died this year lived in Jefferson (2), Lancaster (3) and Mifflin (1) counties. Its update lists 1,467 cases in 45 counties so far in 2026, 34 of them newly confirmed since November 2, and 283 hospitalizations. It counts 5 cases among vaccinated people, "less than 1% of cases."

What is confirmed, and what is not

In October, the Franklin County coroner made public the death of a county resident. That is a different case. DOH says it "is aware of a reported death of a Franklin County resident in October," but that as of November 4 its investigation "has not yet found any Franklin County cases meeting the required criteria to be confirmed as a measles-associated death." DOH's count of six does not include it.

To count as measles-associated under DOH's definition, a death "must occur within 30 days of symptom onset in an individual with clinical evidence of a measles infection and a positive laboratory test," and must not be due to unrelated causes, such as a car crash.

Pennsylvania's figures are the state's own. CDC's national page, last updated on October 30, counts 4,852 confirmed measles cases in the United States in 2026 as of October 29, 4,834 of them reported by 47 jurisdictions. CDC says "states have the most up-to-date information about cases and outbreaks in their jurisdictions." It says 96% of those cases are outbreak-associated, and its data show 96% of 2026 cases were unvaccinated or of unknown vaccination status.

Check your vaccine records

This is the main thing to do at home, and it costs nothing. CDC says: "If you're unsure whether you've been vaccinated, you should first try to find your vaccination records." There is no national copy: CDC says "there is no national organization that maintains vaccination records," and suggests contacting your state's health department, since some states keep registries.

In Pennsylvania, that registry is PIERS. DOH says its PIERS Public Portal lets adults, and parents or guardians of children under 18, "access, save, and print an official record" of the immunizations their providers reported to it. You sign in with a Keystone Login account.

CDC's schedule is two doses for children, at 12 to 15 months and 4 to 6 years old. Adults are recommended to have at least 1 documented dose, and some adults at higher risk 2. CDC's other evidence of immunity includes a lab test showing immunity or past measles, or birth before 1957. If you find no record and have no other evidence of immunity, CDC says "you should get vaccinated," and adds: "There's no harm in getting another dose if you may already be immune." Its records page says "it is safe to repeat vaccines."

What Pennsylvania's health department advises

DOH says two doses of MMR provide "97% lifetime protection." Its advice for residents:

• People with two documented doses of MMR "do not need another."
• Adults with only one dose, or who can't find their records, "should talk with a health care provider or pharmacist about getting vaccinated."
• Children 12 months and older with no dose "should get one now and a second dose at least 28 days later."
• For infants 6 through 11 months who live in or travel to counties flagged on the state's measles dashboard for sustained community transmission, DOH recommends an early "zero dose," which doesn't replace the two routine doses.
• MMR is available from health care providers, pharmacies, county or municipal health departments, DOH State Health Centers, Federally Qualified Health Centers and the Vaccines for Children program.

Know the signs, and call before you go in

CDC says measles usually begins with a high fever, cough, runny nose and red, watery eyes, and that the rash "appears 3 to 5 days after the first symptoms." It spreads easily: CDC says it "can live for up to 2 hours in an airspace after an infected person leaves an area," and that people can spread it from 4 days before through 4 days after the rash appears.

If you have symptoms, CDC says to "call a doctor or hospital right away" to let them know. They may make special arrangements to see you without putting other patients at risk. CDC says to "stay home until the fifth day after you develop the rash." In Pennsylvania, DOH says people who believe they were exposed and have symptoms should contact their provider or call its hotline, 877-PA-HEALTH (877-724-3258).

CDC says to go to an emergency department immediately if symptoms get rapidly worse, or for warning signs such as trouble breathing, dehydration, confusion or severe weakness, and, in young children, a blue color around the mouth, low energy or difficulty feeding. It says to have someone call ahead so the hospital knows a person with measles is coming.

If you were exposed

CDC says: "If you've been exposed to someone who has measles, immediately call your healthcare provider." Timing matters. CDC says that if you get MMR vaccine "within 72 hours" of first being exposed, you may get some protection or have milder illness, and that people at high risk of severe disease may be given immune globulin within 6 days.

If you aren't immune and don't get MMR or immune globulin after the exposure, CDC says to ask your provider when you can no longer make others sick, which "may be up to 21 days" after the exposure. During that time, it says to stay away from places such as schools, hospitals and childcare centers.

Traveling, and who should check first

CDC says anyone not vaccinated, or unsure, "should be vaccinated against measles at least 2 weeks before international travel," and that infants 6 to 11 months old should get 1 dose before international travel, then 2 more after their first birthday. After a trip, it says: "Watch your health for 3 weeks after you return."

CDC says some people should not get MMR, or should wait. It says to check with a provider first if you are or may be pregnant (CDC says to wait until after pregnancy), have a weakened immune system, or had an allergic reaction to a previous dose.

What you don't need to do

You don't need to buy anything because of this news, and you don't need a new dose if you already have two documented doses. The step that helps is finding your family's records now, so you aren't searching for them while someone is sick. If you are not in Pennsylvania, your own state health department is the place to ask about local cases and records.
