This survey looked at 6534 patients who were hepatitis C negative at
the point they entered the SHCS and who have had at least one other
hepatitis C test since then. In terms of the original route-of-exposure
group they belonged to when diagnosed with HIV, 3333 patients (51%) were
gay men, 3078 (47%) were heterosexual and 123 (2%) were injecting drug
users. For the sake of clarity, patients who were both gay and IDU were
excluded from the study, as were heterosexuals who started infecting
drugs after HIV diagnosis.
Since 1998 there were 167 new cases of
hepatitis C infection of which 101 (60%) were in gay men. But half of
the cases in gay men happened since 2009; in the last three years 51 out
of 65 new cases of hepatitis C (78%) were in gay men.
