Hepatitis B razors without blood can be contagious, try not to share razors with hepatitis B patients. Hepatitis B is spread through blood and body fluids, and it can be spread by sharing utensils and cleaners or having sex with someone infected with Hepatitis B. Although there is no visible blood on the razor of a person with hepatitis B, the razor used by that person may have more or less residual blood cells. If a close contact uses it, he or she may get blood containing hepatitis B virus and thus be exposed to the transmission of hepatitis B virus, so try not to use the razor of a hepatitis B patient. Therefore, try to avoid using daily necessities of hepatitis B patients in daily life. Hepatitis B patients should go to the hospital for regular checkups.
