How long can the hepatitis B virus survive in dried blood?

The hepatitis B virus is known for its resilience and ability to survive outside the human body, particularly in dried blood. Studies indicate that the virus can remain viable for up to 1 week in such environments. This extended survival time is significant due to the potential for transmission through blood or bodily fluids, emphasizing the need for strict biohazard safety practices in healthcare settings.

This duration of survival means that surfaces contaminated with blood potentially pose a risk of exposure to the virus for a considerable time, underlining the importance of proper cleaning and disinfection protocols in clinical and laboratory settings. Understanding the longevity of the hepatitis B virus in dried blood is crucial for phlebotomy technicians and other healthcare providers in order to prevent infection and manage the risk of exposure effectively.
