The likelihood of contracting an infectious disease from a barbershop towel for a leg injury is relatively small. The most common infectious diseases are Hepatitis B, Hepatitis C, Syphilis, AIDS, etc. Most of these diseases are spread through blood transmission and sexual contact, and barbershop towels generally do not contain fresh blood, so the possibility of contracting these infectious diseases is relatively small. In addition, after a virus or bacteria leaves its host, it survives outside the body for a short time and generally loses its infectious activity. Fresh wounds are bleeding with barbershop towels, the surface of the towel may contain some bacteria, which can easily cause wound contamination, pay more attention to the recent observation of the body’s condition, if there is any discomfort is recommended to go to the hospital immediately.
