How long can Hepatitis B survive outside the body?

Hepatitis B virus (HBV) is notably resilient and can survive outside the human body for an extended period. Research has shown that Hepatitis B can remain infectious in dried blood and other bodily fluids for up to 7 days. During this time, the virus retains its ability to cause infection if it enters a susceptible person’s body. This characteristic is particularly important in healthcare settings and other environments where exposure to blood or bodily fluids may occur, emphasizing the need for proper infection control practices.

The 7-day survival time underscores the necessity of rigorous cleaning protocols and the importance of using personal protective equipment (PPE) when handling potentially infectious materials. Understanding this fact is crucial for healthcare workers and facilities to prevent the spread of Hepatitis B and protect both staff and patients.
