Pennsylvania Measles Outbreak: Third Death and Disputed Death Counts
By Drooid · · How we work
The Outbreak’s Latest Fatality
On September 12, 2026, a 40-year-old unvaccinated woman from Jefferson County died from measles complications, according to County Coroner Greg Furlong. She had chronic obstructive pulmonary disease, asthma and required 24-hour supplemental oxygen, making her especially vulnerable.
Background & Context
Pennsylvania’s outbreak is the nation’s largest since 1991, with 676 confirmed cases across 37 counties as of September 13, 2026. Hospitalizations total 124 (?18 % of cases); fewer than 1 % of patients have been fully vaccinated. The surge follows a decline in kindergarten MMR vaccination rates linked to vaccine-hesitant messaging. Earlier in the year, two infant deaths in Lancaster County were announced on August 25, 2026, the first measles-related fatalities in the state in 35 years.
Timeline
| Date | Event |
|---|---|
| August 25, 2026 | Pennsylvania Department of Health announces two measles-associated infant deaths. |
| September 4, 2026 | CDC switches mortality reporting to NCHS data. |
| September 10, 2026 | CDC reports 3,294 U.S. measles cases for the year, listing no deaths. |
| September 12, 2026 | Jefferson County coroner confirms death of a 40-year-old woman. |
| September 13, 2026 | Reuters publishes the latest death; CDC still shows no measles deaths. |
Data & Statistics
- State hospitalizations: 124 (?18 % of cases)
- National cases (2026): 3,294
- National deaths reported by CDC: 0
- Vaccination status: >99 % of Pennsylvania cases are unvaccinated; <1 % are breakthrough infections.
- Historical lethality: 1–3 deaths per 1,000 infections.
Why It Matters
The third fatality highlights the risk measles poses to adults with respiratory disease and shows how vaccine-hesitant rhetoric can translate into preventable deaths. Disagreement over death classification threatens coherent public-health messaging and could hamper outbreak-response coordination.
Official Statements & Responses
- CDC Director Erica Schwartz said Pennsylvania had not notified the agency of the September 12 death and reiterated that the CDC will report measles deaths only when NCHS records measles as the underlying cause. She noted the CDC is ready to deploy an Epi-Aid if the state formally requests assistance.
- Pennsylvania Department of Health confirmed a “thorough review” of the Jefferson County case and regular meetings with CDC staff.
- Governor Josh Shapiro criticized Health and Human Services Secretary Robert F. Kennedy Jr.
- Secretary Robert F. Kennedy Jr. questioned the legitimacy of the infant deaths, later acknowledging one was measles-related while maintaining the other was not.
On-the-Ground Reports
Coroner Greg Furlong described the woman’s condition as “pretty extensive” and noted recent exposure to a confirmed measles case.
Conflicting Reports & Gaps
- State vs. Federal Counts: Pennsylvania counts three measles-associated deaths; the CDC dashboard shows none and notes no NCHS death records for 2026.
- Infant Death Classification: Lancaster County coroner listed measles as a “significant condition” for a newborn who died of a ruptured spleen; Pennsylvania classifies both infant deaths as measles-associated, while the CDC has not included either.
- Lack of Standard Definition: The CDC is developing a standardized case definition for measles deaths, leaving current reporting inconsistent across jurisdictions.
