Measles Outbreak 2025: Fourth US Death Reported in Pennsylvania 2026

The measles outbreak 2025 has turned deadly again, with Pennsylvania health officials confirming a fourth person has died from measles-associated illness. This marks the worst year for the disease in the US since 1992, and all four deaths have occurred in the state.

Measles Outbreak 2025: A Grim Milestone

Pennsylvania has reported nearly 700 cases of measles, making it the epicenter of the nation's worst outbreak in more than three decades. The latest death was an 18-year-old Mifflin County resident who was diagnosed with encephalomyelitis, a rare and severe neurological complication of the virus.

"My thoughts are with the two families who lost loved ones to this highly-contagious virus, as Pennsylvania faces the worst measles outbreak in more than three decades," Dr. Debra Bogen, Pennsylvania's secretary of health, said in a statement. "We remain committed to working with our partners across Pennsylvania to stem this outbreak and prevent more deaths."

Why the CDC Isn't Counting These Deaths

Due to changes by the Trump administration in how measles deaths are reported, the Centers for Disease Control and Prevention (CDC) does not include any of these four deaths in its national tally. This reporting shift has raised concerns among public health experts who rely on accurate data to track and combat outbreaks.

Three people died in 2025, and the fourth death was announced Tuesday. The discrepancy highlights the importance of state-level reporting and transparent communication during health crises.

Measles Symptoms and Risks

Measles is a highly contagious virus that can lead to severe complications, including pneumonia, encephalitis, and death. According to health officials, one to three people per 1,000 die from measles-related complications. Up to one in five infected individuals will be hospitalized.

Common symptoms include high fever, cough, runny nose, red eyes, and a characteristic rash. The virus spreads easily through coughing and sneezing, and it can linger in the air for up to two hours.

Vaccination: The Best Defense

The MMR (measles, mumps, and rubella) vaccine is highly effective at preventing measles. Two doses are about 97% effective, and one dose is about 93% effective. Before the vaccine, measles was a common childhood disease, but it was eliminated in the US in 2000 thanks to widespread vaccination.

However, declining vaccination rates in recent years have allowed outbreaks to resurge. Pennsylvania's agricultural areas with lower vaccination coverage have been particularly hard hit.
