Objective:
The aim of this study was to evaluate the incidence of new hepatitis C virus (HCV) infections, based on their sexual orientation, human immunodeficiency virus (HIV) status, geographical regions and coinfection with other sexually transmitted diseases (STDs).
Methods:
This study was carried out at the Sandoval Health Center, reference clinic of Sexually Transmitted Diseases (STDs) in Madrid. All HCV seronegative individuals who were reanalyzed for this virus were included, between January 2010 and December 2016.
Results:
A total of 59 new diagnoses of HCV were diagnosed. The proportion of men who have sex with men (MSM) diagnosed with HCV was 37% in 2010 and 75% in 2016 and was even higher in the group of coinfected with HIV/HCV (94%). A total of 67 seroconverters for HCV were detected (1.2%) of which 100% were MSM. The proportion of HCV seroconverters with HIV was 89%.
Conclusions:
HCV infection continues to be a current health problem, especially in HIV-positive MSM.
