s probably unlikely, in the first place, that the virus would even survive
on a
razor... but there is a bit of risk, so why even have that risk when it can be completely avoided?
Toothrbushes are the same thing. Peoples gums are sensitive, and may sometimes bleed and cause the same thing.
Again, the virus is very sensitive outside of cells and the body. It's unlikely to survive on those items, but, it is a safety precaution. There is a possible risk, and they want you to know about it.
