It is possible for a wound to become infected when it touches the blood of a patient with hepatitis B. As long as this wound is relatively fresh, the blood of a patient with hepatitis B may enter the circulation of the person who comes into contact with it through the wound, thus causing infection. If the wound has been many days old and has completely scabbed over, it can be equated to intact skin, in this case there is no need to worry about being infected. Hepatitis B patients who are triple positive and have not taken oral antiviral medications, and who generally have high quantities of Hepatitis B virus DNA in their blood circulation, exceeding 10^3 or 10^4, have a higher likelihood of transmitting Hepatitis B to their contacts. If the hepatitis B virus DNA quantification in the blood circulation of the patient with hepatitis B is relatively low, and the patient with triple III oral antiviral medication or the patient with triple III, the possibility of transmission will then be smaller, but even so, the possibility of infection can not be completely ruled out.
