Men having sex with men (MSM) are at a higher risk of Hepatitis C. The chances of Hepatitis C are even more in HIV-positive men.
Sexual transmission is the major contributor but injection infusions and blood transfusion are also some other sources.
HIV positive men are already at a higher risk with the depreciation in their immune system.
Rectal fluid samples, despite the absence of blood in them have shown positive results for HCV in most of the cases.
The blood results of those with higher viral loads are prone to shed HCV into the rectum and at higher levels.
Rectal transmission of hep C in HIV-infected MSM is caused by sexual transmission of body fluid or abrasions.
