Bleeding wounds are generally not infected with infectious diseases when wiped with a barbershop towel; if the towel is non-disposable, there is a very low probability of contracting an infectious disease. Barbershop towels are usually cleaned and disinfected for customers to use, so usually the towels do not carry infectious diseases, even if the bleeding wound is wiped with a towel, it will not be infected with infectious diseases. If the towel is used repeatedly, there is a very low risk of infectious diseases. The premise is that the previous user of the towel had some kind of blood-borne disease, such as hepatitis B, syphilis, AIDS, hepatitis C, etc., and left blood on the towel. If the blood on the towel comes into contact with the bleeding wound of the next user within a short period of time, there is a possibility of infection, but this probability is very low. When a bleeding wound exists, it can be disinfected with iodophor and bandaged with a sterile gauze block to avoid contact with another person’s blood.
