Can HIV be transmitted through baber shops

Razors are used for shaving in barber shops. Even if there are no evident cuts during shaving, there are always micro abrasions on the shaved skin. These abrasions or frank cuts on the skin can deposit blood and tissue fluid on the razor. If this blood contains HIV and the same razor is used on another person, HIV can be transmitted to that person. One should always insist on the use of a new razor blade for shaving in a barber shop. It is also preferable that the handle of the razor blade is disinfected before use.
