The quick answer is “NO”. Razors can potentially spread both skin infections and blood borne viral infections such as Hepatitis B, C, and HIV.
It’s easy to understand sharing razors spread skin infections.You should realize some people’s skin harbors germs without any sign of infection. Those germs can become a problem when they spread to another’s skin – no judgment, it’s just fact.
Some of the contagious germs that you can get by sharing a razor include the bacteria called Staph aureus. It is now estimated that as many as 30% of people carry “staph” asymptomatically on their body. Staph can reside in skin folds and/or in the nasal cavity without causing pimples, sores, or redness. We call this “Staph colonization” meaning the bacteria resides on the person without causing trouble. This is the same Staph bacteria that can cause impetigo, shaving folliculitis and worse. It can become resistant to the family of antibiotics that include Methicillin and thus called MRSA (Methicillin Resistant Staph Aureus).
Additional germs on the skin that can be spread by razors include Candida yeast, the fungi that causes athlete’s foot and jock itch, and the viruses that causes herpes, warts, and molluscum contagiosum. I’ve seen all of these common germs spread by razors. Don’t share razors.
