On January 30, 2026, the Pennsylvania Health Department (DOH) identified five confirmed cases of measles in Lancaster County. These are the first cases to be identified in Pennsylvania for 2026.
• Health care providers should maintain a high index of suspicion for measles in patients presenting with fever and rash, especially those who are unvaccinated. Providers should also ask about recent exposures or being a contact with a person known to have measles in those presenting with compatible illness.
• The DOH urges all Pennsylvanians to stay up to date on their MMR vaccinations.
• To minimize exposure, providers should implement appropriate infection-prevention measures when measles is suspected and notify the infection control personnel.
• Providers must immediately report suspected measles cases to local public health authorities or to DOH at 877-PA-HEALTH (877-724-3258). Providers should not wait for lab
confirmation to notify public health if measles is suspected.
