Hairdressers and barbers
The hepatitis C virus can be present in very small traces of blood, often invisible to the naked eye. Equipment used by hairdressers and barbers including scissors, clippers and razors may have been exposed to infected blood. If they are not sterilised or cleaned every time they are used, they pose a risk of transmission.
The likelihood of this happening is very difficult to estimate as it will depend on a number of variables. If the skin was either grazed or cut at a barbers or hairdresser then you may be at some risk.
Risk will increase if this happened abroad in a country with a high HCV prevalence. However, blood tends to flow out of the body when you get cut, which may lessen the chances of infection.
