Hepatitis C is a viral infection that causes liver inflammation, sometimes leading to serious liver damage. The hepatitis C virus (HCV) is transmitted through contact with infected blood, most commonly through sharing needles or other equipment used to inject drugs. Research in the area of hepatitis C focuses on understanding the virus, developing new treatments and vaccines, and finding ways to prevent transmission. Some of the key areas of research include studying the natural history of the disease, including how it progresses over time; developing new antiviral medications that can effectively cure the infection; and exploring ways to improve screening and diagnosis of hepatitis C. Overall, research in hepatitis C aims to improve the outcomes for individuals infected with the virus and reduce the burden of liver disease worldwide.
