The virus that causes hepatitis c (hcv) can be sexually transmitted and the risk is directly related to the frequency of intercourse, the findings from a new study suggest. However, the association does not seem to be very strong.

Contact with infected blood is the main route by which hcv is transmitted, lead author Dr. Veysel tahan, from marmara university in istanbul, turkey, and colleagues note. However, in up to 50 percent of cases, a transmission route is never identified.
