[Pennsylvania Reports 55 New Measles Cases Amid Ongoing Statewide Outbreak]
The Pennsylvania Department of Health (DOH) announced on Friday that 55 new measles cases had been reported in the state since Wednesday, and officials said they continue to work to contain the outbreak that has spread across dozens of counties.
In a accompanying press release, the DOH reported that 890 measles cases had been confirmed across 39 counties within the state this year. To date, the outbreak has caused 173 hospitalizations and four measles‑related deaths.
State health officials noted that fewer than one percent of the cases involved individuals who were vaccinated against measles, and data showed that 31 percent of the infections involve persons under 18 years old.
Beyond reporting the 55 new cases over a two‑day span that began on Wednesday, the DOH highlighted its proactive engagement with residents, community groups, and healthcare providers to curb the outbreak—emphasizing the provision of factual information and encouraging MMR vaccination.
This state health update emerged amid commentary from former FDA chief Robert F. Kennedy, a prominent vaccine skeptic, who questioned the validity of the reported infections and suggested they might have been politically motivated.
Earlier, in August, the new CDC director instructed staff to exclude two measles‑associated deaths reported by Pennsylvania from the nation’s overall count, stating that further review of supplemental information was underway.
Lancaster County leads the state in case numbers, with 359 confirmed instances to date, according to official statistics.
Since the outbreak began in late April, more than 5,300 MMR vaccinations have been administered at 165 pop‑up vaccination sites throughout the affected areas.
Additional vaccination sites are slated to open in the coming weeks and months, driven by community demand and interest.
Cumulative numbers indicate that health center staff have delivered more than 7,900 MMR doses this year, while hospitals report a surge of residents seeking the vaccine.
The DOH emphasized that full vaccination remains the best defense, noting that the MMR vaccine strengthens immunity and confers 97 percent lifelong protection.
Measles is a highly contagious viral disease that can cause serious health problems; when severe outcomes occur, death results in approximately one to three cases per 1,000 diagnoses.
Although the United States declared measles eliminated in 2000, recent transmission continues in under‑immunized communities.
Health officials warn that measles spreads via airborne particles released during coughing or sneezing, remaining viable in indoor air for up to two hours.
Typical symptoms appear seven to fourteen days after exposure and may include fever, a dry cough, nasal congestion, watery eyes, culminating in a widespread rash.
The CDC recommends that two doses of the MMR vaccine provide the strongest protection against measles.
As of September 24, the CDC records more than 3,600 confirmed measles cases for the year, with 2,289 cases reported statewide for 2025.
