The Pennsylvania Department of Health is advising patients of a York County dentist that they might be at risk for infection after an investigation discovered the dental facility did not follow appropriate infection control procedures.



To date, the investigation has found Dr. Jacqueline A. Marcin did not follow appropriate procedure to properly clean, disinfect or sterilize devices at her York dental office, located at 1820 E. Market St.

As a result, the Department of Health is recommending hepatitis B, hepatitis C and human immunodeficiency virus (HIV) testing for current or former patients who had dental procedures performed directly by Dr. Marcin, such as fillings, tooth removals, denture fittings and other procedures.

Testing is not currently advised for patients who only received routine cleanings or checkups performed by other staff members. Patients should see their doctor to discuss testing options.


“We understand that patients of Dr. Marcin might be worried in light of this news,” Secretary of Health Michael Wolf said. “We have not received any related reports of disease transmission or illness at this time. However, as a precautionary measure, we are recommending current or former patients of Dr. Marcin get tested.”

The departments of Health and State conducted a joint, unannounced site visit of Dr. Marcin’s dental practice on April 24. The Pennsylvania State Board of Dentistry temporarily suspended Dr. Marcin’s dental license on April 29.


“We worked with the Department of State to immediately address the infection control problems and prevent any future potential exposures,” Wolf said. “And although this is an ongoing, complex investigation, we feel it is extremely important to provide Dr. Marcin’s patients with information so they can better protect their health. We will continue to share relevant developments as needed to protect the public’s well-being.”

A special, toll-free hotline has been set up by the Department of Health for this investigation. Dr. Marcin’s patients can call 1-855-265-4613 for more information.

Hepatitis B, hepatitis C and HIV are serious medical conditions that may not cause any outward symptoms in infected patients for many years. Visit the Department of Health’s website at to learn more.
