It is not possible to generalize how long the hepatitis B virus can survive, as the survival time of the virus varies significantly from 10 minutes in boiling water to 10 hours at 65°C. The virus is the causative agent in the formation and development of viral hepatitis B. However, the virus does not directly kill liver cells. Hepatitis B virus is the pathogen that causes the formation and development of viral hepatitis B. The invasion of the virus affects the functioning of the liver, but the virus does not directly kill liver cells. Hepatitis B virus itself is a DNA virus with an envelope, its resistance is relatively strong, can survive for 10 hours at 65 ℃, in boiling water can survive for 10 minutes, high-pressure steam can also inactivate the virus. In addition, peroxyacetic acid and ethylene oxide can also play a good role in inactivating the hepatitis B virus. Individuals infected with the hepatitis B virus should seek prompt medical attention and follow the doctor’s instructions to develop and implement an appropriate treatment plan based on the individual’s actual condition.
