Pennsylvania has witnessed its fifth measles-related death in 2026 amid a persistent outbreak that has now affected 943 confirmed cases throughout 39 counties.
According to the Pennsylvania Department of Health, the recent fatality involved an unvaccinated resident from Lancaster County who had tested positive for measles. Officials have chosen not to release any additional details about the individual to protect their privacy.
This death brings the total of measles-associated fatalities in Pennsylvania to five this year, following a previous death reported about two weeks ago. Due to changes in how the Trump administration reports measles deaths, the CDC has not included these deaths in its national count.
As of September 28, the state reported 40 new positive cases. The outbreak has spread to 39 counties, with a total of 943 confirmed cases, 176 of which resulted in hospitalizations, alongside the five deaths linked to the disease.
Notably, only four of these confirmed cases have involved vaccinated individuals, accounting for less than 1% of the total cases in the state.
Health officials have noted that daily case numbers can fluctuate, but tracking these changes helps residents and healthcare providers gauge the extent of community transmission and inform the state’s response efforts.
The agricultural regions of Lancaster and Mifflin counties have been particularly impacted by the outbreak. Other states like Utah, Florida, Virginia, and Texas have also recorded dozens of cases according to Johns Hopkins University tracking.
Since the outbreak began in late April, more than 5,500 vaccinations for measles, mumps, and rubella (MMR) have been administered through 180 pop-up clinics in at-risk communities, as reported in a recent statement.
Further vaccination clinics are in the pipeline for the upcoming weeks and months, depending on how much interest and need there is in the communities.
More than 3,600 measles cases have been documented across the U.S. in 2026. Although measles was declared eliminated in the U.S. in 2000, it’s uncertain whether this status can be maintained given the resurgence of outbreaks.
Measles is recognized as one of the most contagious diseases, but the MMR vaccine effectively prevents about 97% of cases.
Vaccination rates among kindergarteners, a critical metric, have been gradually declining. Some experts suggest this trend is partly due to misinformation and confusion about vaccines being promoted during the Trump administration.
Earlier this month, Pennsylvania sought emergency aid from the CDC in light of the ongoing outbreak, warning that this request could be rescinded unless the agency acknowledged the reported measles-associated deaths.
This back-and-forth began after Robert F. Kennedy Jr., the U.S. Health Secretary and former leader of an anti-vaccine group, publicly raised doubts about whether the deaths linked to the outbreaks were directly caused by the virus or resulted from other health conditions.
