How long can the Hepatitis B Virus persist on surfaces?

One hour
One day
One week
One month

The correct answer is: One week

The Hepatitis B virus (HBV) is known for its remarkable resilience outside the human body, which is an important consideration in infection control protocols. It can persist on surfaces for an extended period, allowing for potential transmission if someone comes into contact with contaminated surfaces. Research indicates that HBV can remain infectious on surfaces for up to seven days, making it critical for healthcare settings, including those involving dialysis, to follow strict disinfection and contamination protocols. Surfaces that may come into contact with blood or bodily fluids should be regularly and thoroughly cleaned to reduce the risk of HBV transmission. This understanding highlights the significance of proper handling and management of materials in clinical environments to ensure patient safety.
