A measles-infected Kohl's employee may have exposed shoppers and staff at the East Lampeter Township store on May 21, 23, 25 and 26, prompting Pennsylvania health officials to issue a public warning.
The employee was unvaccinated, and officials urged anyone unvaccinated or showing symptoms to call a healthcare provider or the state hotline; symptoms can appear 7 to 21 days after exposure.
The infected worker is no longer a risk to the general public, but contact tracing is still underway, and Kohl's said the store remains open under health department guidance.
Lancaster County has logged 10 measles cases in the past month and 18 of Pennsylvania's 38 cases this year, part of a wider regional outbreak that also hit Lebanon, Berks and Dauphin counties.
Nationwide, CDC data show 1,983 measles cases as of May 28, underscoring a broader resurgence as officials push MMR vaccination, which is 97% effective after two doses.
