Measles exposure prompts health alert for Montgomery County shoppers
A person with measles visited a Nissan dealership in Royersford and a Wawa in Limerick (Montgomery County) from Feb. 16–19, 2026. Because measles can linger in the air or on surfaces for up to two hours, the exposure window includes the visit times plus two hours after. Anyone exposed should monitor for symptoms for 21 days and contact a doctor if symptoms develop; vaccination with MMR provides protection for many adults.
