Step-by-step explanation:
The most commonly contracted virus in healthcare settings is Hepatitis B virus (HBV). HBV transmission could be reduced in these settings by ensuring healthcare workers are vaccinated, practicing proper hygiene, using personal protective equipment, and safely handling needles and other sharp instruments.
Despite the decline in HBV infections following the CDC's recommendation for healthcare worker vaccination, there remains a risk, particularly when working with patients who have chronic hepatitis B.
To reduce transmission of HBV in healthcare settings, it is important for healthcare workers to adhere to standard precautions, wear appropriate personal protective equipment, and receive the HBV vaccination.
