Unveiling Hepatitis C: Causes, Impact and advances in treatment

Hepatitis C Virus (HCV) infection continues to pose a major global health issue, with around 58 million chronic cases reported worldwide and about 1.5 million new infections each year. This virus is a primary contributor to chronic liver disease, cirrhosis, and hepatocellular carcinoma (HCC), leading to approximately 290,000 deaths annually (WHO, 2022). The introduction of direct-acting antiviral (DAA) therapies has transformed HCV treatment, with sustained virologic response (SVR) rates surpassing 95% across various genotypes. However, challenges remain in meeting the World Health Organization's target of eliminating HCV as a public health threat by 2030. Key obstacles include low diagnosis rates, as only 21% of those infected with HCV are aware of their condition, and restricted access to treatment, especially in low- and middle-income countries (LMICs).

This article reviews the latest epidemiological trends related to HCV, focusing on the disparities in disease burden and access to healthcare. It discusses innovative diagnostic methods, such as point-of-care testing, and emphasizes the importance of universal screening programs in areas with high prevalence. Additionally, we look at new therapeutic strategies, including pan-genotypic DAAs and their effects on marginalized communities. Lastly, we examine public health initiatives aimed at enhancing HCV prevention, such as harm reduction programs and vaccination efforts for co-infections like hepatitis B.

By integrating findings from recent studies and reports, this article highlights the necessity for collaborative global efforts to address the challenges of HCV elimination. Strategies that emphasize prevention, early detection, and fair access to treatment are crucial for alleviating the HCV disease burden and reaching elimination goals.
