Montgomery County, Pennsylvania health officials are alerting residents to potential measles exposures at a Nissan dealership in Royersford and a Wawa convenience store in Limerick. The exposures occurred between February 16 and February 19, 2026, stemming from a single individual who was contagious with the highly infectious virus. This incident underscores the ongoing risk of measles outbreaks, even with widespread vaccination efforts, and highlights the importance of verifying immunity.
Measles, a highly contagious respiratory disease, can spread quickly through the air when an infected person coughs or sneezes. Symptoms typically include fever, an unexplained rash, cough, congestion, and red, watery eyes. While generally mild in vaccinated individuals, measles can lead to serious complications, particularly in infants, young children, pregnant women, and those with weakened immune systems. As of February 19, 2026, Pennsylvania has reported five confirmed cases of measles, a notable increase from the six cases reported in all of 2024 and the 16 cases in 2025, according to the Centers for Disease Control and Prevention.
The Montgomery County Department of Health and Human Services has released specific dates and times for potential exposure at the two locations:
- Nissan 422 of Limerick, 55 Autopark Boulevard, Royersford, PA 19468: Monday, February 16, 2026, from 8:45 a.m. To 5:00 p.m. And Wednesday, February 18, 2026, from 8:45 a.m. To 7:15 p.m.
- Wawa, 579 N. Lewis Road, Limerick, PA 19468: Monday, February 16, 2026, from 8:30 a.m. To 11:00 a.m., Wednesday, February 18, 2026, from 8:30 a.m. To 11:00 a.m., and Thursday, February 19, 2026, from 11:45 a.m. To 2:15 p.m.
Health officials emphasize that individuals who were present at these locations during the specified times may have been exposed and should monitor themselves for symptoms for 21 days. Measles can remain infectious in the air and on surfaces for up to two hours after an infected person has left the area, increasing the potential for transmission.
Protecting Yourself and Others
Determining your immunity status is the first step in assessing your risk. According to health officials, individuals are generally considered protected from measles if they were born in 1957 or earlier, have received two doses of the Measles, Mumps, and Rubella (MMR) vaccine, or have laboratory confirmation of immunity. If you are unsure of your vaccination history, checking your records or contacting your healthcare provider is crucial.
If you believe you may have been exposed and are not fully vaccinated or protected, health officials advise contacting your healthcare provider or the Montgomery County Office of Public Health for guidance. This proves also vital to watch for the development of measles symptoms – fever, rash, cough, congestion, or red, watery eyes – for three weeks following potential exposure. If symptoms appear, stay home and immediately contact your doctor, alerting them to your potential exposure before your visit to allow for appropriate precautions to protect other patients and staff.
Who is Most Vulnerable?
Certain populations are at higher risk of experiencing severe complications from measles. Infants and children under five years old, pregnant women, and individuals with compromised immune systems – such as those undergoing treatment for leukemia or living with HIV – are particularly vulnerable. The CDC emphasizes the importance of vaccination for these groups to prevent serious illness.
This recent exposure serves as a reminder of the importance of maintaining high vaccination rates to protect the community from preventable diseases. While measles was declared eliminated in the United States in 2000, imported cases and outbreaks continue to occur, particularly in communities with lower vaccination coverage. Continued vigilance and proactive measures are essential to safeguard public health.
Health officials will continue to monitor the situation and provide updates as needed. Residents are encouraged to stay informed and follow the guidance of public health authorities.
