Question

The 2020 Nobel Prize for Physiology and Medicine was awarded to three scientists for their work on HCV. What do you know about this virus and the disease it causes? Is there any vaccine available for this disease?

Ghissu Editorial · Accepted Answer

Hepatitis C virus is an enveloped, positive-sense RNA virus of the Flaviviridae family, spread mainly through blood, that causes silent chronic hepatitis progressing to cirrhosis and liver cancer. No vaccine exists, but oral direct-acting antivirals cure more than 95 percent of patients in 12 weeks.

**Introduction**

The 2020 Nobel Prize recognized the discovery of Hepatitis C virus (HCV), crucial for understanding chronic liver diseases like cirrhosis and liver cancer globally. This breakthrough has enabled targeted diagnosis, treatment, and prevention strategies, significantly impacting public health.

**Institutional Framework and Research Capacity**

1. **National and State Coordination**: ICMR leads hepatitis research nationally, with regional centres like ==ICMR-National Institute of Virology Pune== supporting Andhra Pradesh’s surveillance, diagnostics, and epidemiological studies to monitor HCV prevalence.

2. **Health Infrastructure Support**: Schemes such as Pradhan Mantri - Ayushman Bharat Health Infrastructure Mission⟦1⟧ (PM-ABHIM) bolster state capacity for hepatitis diagnosis and treatment. Andhra Pradesh’s government hospitals and medical colleges provide access to direct-acting antivirals (DAAs), which have revolutionized HCV therapy with high cure rates.

**Implementation Challenges and Disease Impact**

4. **Economic Barriers and No Vaccine**: Despite reduced DAA costs due to generic production in India, affordability remains a challenge in rural and tribal areas. No vaccine exists for HCV, unlike hepatitis A and B, complicating prevention efforts and making safe blood transfusion and harm reduction strategies essential.

**Way Forward**

5. **Expand Screening and Treatment**: Leveraging National AIDS Control Programme⟦2⟧’s outreach experience and ensuring subsidized DAAs through Ayushman Bharat can enhance early diagnosis and treatment access, reducing disease burden.

**Conclusion**

The Nobel-winning discovery of HCV has advanced treatment options, but the absence of a vaccine demands robust screening, treatment, and awareness programs in Andhra Pradesh to achieve the 2030 Sustainable Development Goal of ending viral hepatitis as a public health threat. This aligns with the vision of "Sabka Saath Sabka Vikas" for inclusive health development.
