Back HCV Prevention

Studies Shed Light on Hepatitis C Virus Sexual Transmission among Gay Men

Hepatitis C virus (HCV) transmission among HIV positive gay men has leveled off in Amsterdam -- one of the first cities with an outbreak of apparently sexually transmitted HCV infection -- and it continues to be rare among HIV negative men who have sex with men, according to recent studies. Other research looked at HCV sexual transmission among HIV positive and negative men in Switzerland, and at the association between HCV viral load in blood and semen.

EASL 2014: Researchers Look at Treatment as Prevention for Hepatitis C

Widespread hepatitis C treatment with effective new direct-acting antivirals could dramatically reduce hepatitis C virus (HCV) transmission, but making this work on a large scale will require efforts to scale up HCV screening and bring down drug costs, according to several presentations at the EASL International Liver Congress this month in London.

AASLD 2013: HCV Levels in Semen May Correspond to Blood Viral Load

HIV positive men with higher hepatitis C virus (HCV) RNA levels in their blood during acute infection were more likely to have HCV in their semen as well, which may raise the risk of sexual transmission, researchers reported last month at the 64thAASLD Liver Meeting in Washington, DC.

EASL 2014: Treatment as Prevention for Drug Users Could Slash HCV Prevalence

A combination of increased testing, improved linkage to care, and earlier treatment with interferon-free regimens has the potential to substantially reduce the incidence and prevalence of hepatitis C among people who inject drugs in France over the next 10 years, as well as reducing the burden of disease arising from cirrhosis over 40 years, according to a study presented at the 49th EASL International Liver Congress (EASL 2014) last week in London.

Hepatitis C Virus Can Live on Surfaces for Up to 6 Weeks

Hepatitis C virus (HCV) in dried droplets of blood or plasma can remain infectious on uncovered surfaces at temperatures of 4° or 22° C (39° or 72° F) for up to 6 weeks, resulting in potential for transmission in healthcare settings or during injection drug preparation, researchers reported in the November 23, 2013, advance edition of the Journal of Infectious Diseases.
