Hepatitis C Nobel Prize

Earlier this month the Nobel Prize in Physiology and Medicine was jointly awarded to Harvey J Alter, Michael Houghton and Charles M Rice for the discovery of the Hepatitis C virus. This helped push our understanding of blood-borne hepatitis, a major global health problem that is one of the leading causes of cirrhosis and liver cancer alongside Hepatitis B. It led the way in introducing new tests for chronic hepatitis as well as new treatments that have saved the lives of millions.

HEPATITIS

Hepatitis is the inflammation of your liver, the largest solid organ in your body. Though there are numerous other causes of hepatitis, including alcohol abuse, drugs and toxins (including paracetamol overdose), and autoimmune disorders (such as Wilson’s disease), viral infections are the most common worldwide causes for hepatitis. Hepatitis A was the first to be discovered, transmitted by polluted food and water, and results in a short-term transient hepatitis. Hepatitis B on the other hand is transmitted through blood and is more of an issue as it can lead to chronic cirrhosis and possible liver cancer. It can remain indolent in a person, causing disease long after the initial infection.

Blood borne hepatitis was first discovered in the 1960s, when it was found that some patients would become ill after receiving blood transfusions. Despite this discovery and new tests for Hepatitis B reducing the number of transfusion related hepatitis, a large number of cases remained.

NOT A, NOT B

Harvey Alter, working at the US National Institute of Health, was studying the occurrence of hepatitis in blood transfusion patients. His team showed that blood from these infected patients could transmit the disease to chimpanzees, resulting in hepatitis. This agent had the properties of a virus, one that was “non-A, non B” hepatitis.

Further investigation into the virus would require the input of Michael Houghton, working for Chiron pharmaceutical. His team created a collection of DNA fragments found in the blood of infected chimpanzees. Though the majority of these fragments were from the chimpanzee, enough were from the virus. They were able to utilise this information to identify antibodies against the suspected virus, and ultimately identify it as the flavivirus Hepatitis C.

The final piece of the puzzle was shown by Charles M Rice, a researcher at Washington University, St Louis – could the virus alone cause hepatitis. He studied the RNA of Hepatitis C to identify regions that may be used for replication, and areas that might hinder replication. This was key as the virus can lay dormant for years, replicating at a slow rate before causing damage to the liver. For researchers, this was an issue as it was not feasible to wait years and see if the suspected virus caused hepatitis. By genetically engineering the viral genome, he developed a variant of Hepatitis C that would only multiple rapidly and have no mechanism to inactivate itself for dormancy. This strain caused rapid changes to the livers of infected chimpanzees; the same changes seen in hepatitis patients.

. ;.,hrvxzThe impact was significant. Prior to this, receiving a blood transfusion was like Russian Roulette. You were receiving life saving therapy, but it coZuld also be a hidden death sentence. Now that hepatitis had been discovered, it became possible to screen patients prior to donation, to screen blood transfusion bags, and to start developing treatments for the virus.

The fight is not over yet. There are still over 70 million people who still live with the virus, and it still kills around 400,000 a year. Its only very recently that we have found treatments that can reduce the viral load in patients to levels that they are considered cured. This treatment remains expensive, and we are very far away from eradication itself.

Monthly Healthy Potluck at Health Hubs: Building Community-Centered Preventive Wellness in India

India is facing a growing burden of lifestyle-related health conditions, including diabetes, obesity, hypertension and heart disease. According to ICMR and NFHS-5 data, dietary habits play a central role in the development and prevention of these conditions. While awareness around nutrition is increasing, sustaining healthy eating habits remains a challenge for many individuals.

The Monthly Healthy Potluck at Health Hubs is a community-driven initiative designed to address this gap. By bringing people together around nutritious food, shared learning and expert guidance, these potlucks transform healthy eating from an individual responsibility into a collective experience.

SecondMedic supports these events as part of its broader preventive healthcare mission, combining community engagement with medical expertise and digital health tools.

Why Community-Based Nutrition Initiatives Matter in India

1. Rising lifestyle disease burden

ICMR reports show that diet-related conditions account for a significant proportion of non-communicable diseases in India. Excess sugar, refined carbohydrates and processed foods are common contributors.

2. Nutrition knowledge gaps

NFHS-5 highlights widespread deficiencies in:

protein intake
micronutrients
dietary diversity

Community events help translate knowledge into practice.

3. Behaviour change is easier together

Research published in The Lancet suggests that group-based interventions are more effective in sustaining lifestyle changes than isolated efforts.

4. Cultural relevance of shared meals

Food is deeply social in Indian culture. Potlucks leverage this tradition to promote healthier choices without imposing rigid rules.

What Is the Monthly Healthy Potluck at Health Hubs?

The Monthly Healthy Potluck is a recurring wellness event hosted at designated Health Hubs. Participants bring healthy, home-prepared dishes and engage in guided discussions about nutrition, ingredients and portion balance.

The goal is not calorie counting, but mindful, informed eating that aligns with preventive health principles.

Key Components of the Healthy Potluck Program

1. Nutritious Home-Cooked Food

Participants are encouraged to prepare dishes using:

whole grains
seasonal vegetables
lean proteins
healthy fats
minimal added sugar and salt

This showcases practical, everyday meals rather than restrictive diets.

2. Nutrition Education in Simple Language

Dietitians and healthcare professionals explain:

why certain ingredients are beneficial
how portion sizes affect metabolism
ways to modify traditional recipes for better health

This bridges the gap between theory and daily cooking.

3. Peer Learning and Motivation

Participants learn from each other’s recipes, challenges and successes. This shared experience builds motivation and accountability.

4. Preventive Health Focus

Discussions link food choices to prevention of:

diabetes
heart disease
obesity
gut disorders
nutrient deficiencies

The emphasis is on long-term wellbeing, not short-term fixes.

Who Can Benefit from Monthly Healthy Potlucks?

Working professionals

Learn quick, balanced meal ideas suited for busy schedules.

Families
