Answer

I am not aware of any studies which have tried to determine how long infectious virus remained on a razor. However, transmission of hepatitis C is related to drug use, where there is a large exposure to infectious virus, or to accidental needlestick exposures, most of which occur with hollow bore needles. Therefore, the risk of transmission usually requires a certain inoculum of virus that is in a hollow bore needle.

Sharing razors is not recommended; however, transmission from person to person through simple razor sharing is not documented. Dr. McGovern
