The Pennsylvania Department of Health has launched a new online measles dashboard to give families and communities more timely information about cases across the commonwealth, as officials step up vaccination efforts in Lancaster County, the center of the state’s largest outbreak this year. Announced by the Shapiro administration, the dashboard includes county-by-county case counts, along with data on patients’ ages, hospitalizations and vaccination status. It will be updated every Monday, Wednesday and Friday afternoon. “This new measles dashboard is part of the Shapiro Administration’s commitment to boost public access to information and provide transparency in our work to protect public health,” Health Secretary Dr. Debra Bogen said.Bogen said the department is continuing its efforts to contain the spread of the highly contagious virus, particularly among unvaccinated residents. She said state health center staff have administered more than three times as many measles, mumps and rubella, or MMR, vaccinations in Lancaster County so far in 2026 as they did during all of 2025. Lancaster County at center of outbreakLancaster County has reported the highest number of measles cases in Pennsylvania this year, accounting for 67 of the state’s 109 total cases as of July 15. Statewide data also shows:109 total cases reported this year8 new cases in the last seven days20 hospitalizations42% of cases in people under 180 deaths0% fully vaccinated among reported casesThe Department of Health said it has administered more than 600 vaccine doses to Lancaster County residents through pop-up measles clinics since cases were first identified there in late April.

Vaccine outreach expandsHealth officials say vaccination remains the most effective protection against measles. Two doses of the MMR vaccine provide 97% lifetime protection against infection, according to the department. In late June, the department issued guidance allowing health care providers to vaccinate infants as young as 6 months old during the outbreak, citing the heightened risk measles poses to young children.
