What does it mean for a licensee to be "infected with the Hepatitis B virus"?

A licensee being described as "infected with the Hepatitis B virus" signifies that they test positive for specific Hepatitis B antigens. This indicates an active infection, which can be identified through tests that detect the presence of hepatitis B surface antigen (HBsAg) in the bloodstream. It is crucial for health professionals, including dental hygienists, to be aware of their Hepatitis B status due to the potential risks associated with the transmission of the virus in clinical settings.

In contrast, having previously contracted Hepatitis B does not necessarily mean the individual is currently infectious; they might have resolved the infection and developed immunity. Being immune to Hepatitis B would signify a previous infection or successful vaccination, meaning the individual does not currently pose a risk of transmitting the virus. Lastly, being vaccinated against Hepatitis B does not equate to being infected; rather, it indicates a proactive measure taken to prevent the infection altogether.
