Global control of hepatitis C: where challenge meets opportunity

Area of Science:

• Hepatology
• Virology
• Public Health

Background:

• Hepatitis C virus (HCV) infection affects an estimated 185 million people globally, with many unaware of their diagnosis.
• Undiagnosed HCV infection poses significant risks for developing severe liver conditions, including cirrhosis and hepatocellular carcinoma (HCC).
• The incidence of HCV-related liver diseases is projected to increase in the next decade, highlighting an urgent public health concern.

Purpose of the Study:

• To outline the current landscape of hepatitis C virus (HCV) infection, emphasizing both persistent challenges and emerging opportunities.
• To underscore the critical need for a robust public health response to combat HCV.
• To discuss the potential for viral eradication through advancements in prevention and treatment.

Main Methods:

• This is a narrative review synthesizing current data on HCV epidemiology, disease progression, and therapeutic advancements.
• The analysis considers global prevalence, diagnostic challenges, and the impact of new interventions.
• It evaluates the balance between ongoing transmission/risk and the efficacy of modern public health strategies.

Main Results:

• New HCV infections continue to occur, contributing to a substantial global burden of disease.
• A significant proportion of infected individuals remain undiagnosed, increasing their risk for severe liver complications.
• Effective prevention, early detection, and curative treatments are now available, offering a pathway to viral eradication.

Conclusions:

• The future trajectory of HCV infection depends on effectively addressing challenges like undiagnosed infections and increasing access to care.
• Leveraging advancements in diagnostics and antiviral therapies is crucial for achieving viral eradication.
• A vigorous and coordinated public health response is essential to overcome the remaining hurdles in the HCV epidemic.
