While I was reading the news online I came across this rather interesting report.
It has recently come to light that a healthcare worker infected two people with the Hepatitis C virus while working at a Hospital in Wales. As a result hundreds of patients in other areas of Wales who may have come into contact with the health worker are also being contacted, so that they can be diagnosed and effective treatment can be provided if necessary.
The risk of contracting the virus is low as it is transmitted through blood-to-blood contact and very rarely through sexual intercourse. So a patient can only be affected if the healthcare worker leads or assists in an operation or procedure on the patient but even in such circumstances transmission is very rare. But even if the risk is low tests are being provided as precaution.
