What Is Hepatitis ABC?
Understanding Hepatitis A, B & C
Simple, clear answers — what each type is, how it spreads, its symptoms, and how it is treated or prevented.
Hepatitis A, B, and C are three viral infections that cause liver inflammation. Hepatitis A spreads through contaminated food or water and is short-term. Hepatitis B spreads through blood and body fluids and can become chronic. Hepatitis C spreads mainly through blood contact, is often silent for years, but is now curable in over 95% of cases.
Hepatitis viruses attack and inflame liver cells, disrupting the liver's vital functions over time.
Hepatitis means inflammation of the liver. The liver filters blood, aids digestion, and removes toxins from the body. When it becomes inflamed, these essential functions are disrupted.
The most common cause worldwide is a viral infection. There are five types of hepatitis viruses (A, B, C, D, and E), but A, B, and C are responsible for the vast majority of cases globally — including in India.
Here is a simple visual overview of how the three most common viral hepatitis types differ from each other:
Hepatitis A
- Spreads via food & water
- Short-term (acute) only
- Usually self-limiting
- Vaccine available ✓
- No chronic risk
- Common in India
Hepatitis B
- Spreads via blood/fluids
- Can become chronic
- Risk of cirrhosis/cancer
- Vaccine available ✓
- Managed with antivirals
- 40M carriers in India
Hepatitis C
- Spreads via blood contact
- Mostly becomes chronic
- Silent for years
- No vaccine yet
- Curable in 95%+ cases
- 8-12 week tablet course
Hepatitis A is caused by the Hepatitis A virus (HAV). It is very common in India, especially in areas with poor sanitation. It spreads when a person consumes food or water that has been contaminated with the feces of an infected person.
- Eating food prepared by an infected person with poor hand hygiene
- Drinking contaminated water or using contaminated ice
- Eating raw shellfish sourced from polluted water
- Close physical contact with an infected person
- Travelling to regions with low sanitation standards
- Sudden onset of fatigue and body weakness
- Nausea, vomiting, and complete loss of appetite
- Pain or discomfort in the upper right abdomen (liver area)
- Yellowing of the skin and whites of the eyes (jaundice)
- Dark-coloured urine (tea-coloured) and pale stools
- Low-grade fever and joint pain
Good to know: Hepatitis A almost always resolves on its own within 2–6 weeks. It does not become chronic. Treatment focuses on rest, plenty of fluids, a light diet, and strict avoidance of alcohol during recovery.
- Get vaccinated — the Hepatitis A vaccine requires just 2 doses and is highly effective
- Wash hands thoroughly with soap before eating and after using the toilet
- Drink only clean boiled or sealed bottled water
- Avoid raw or street food prepared in unhygienic conditions
Hepatitis B is caused by the Hepatitis B virus (HBV). It is far more serious than Hepatitis A. In India, approximately 40 million people are chronic Hepatitis B carriers. Without proper treatment, it can lead to cirrhosis, liver failure, or liver cancer over time.
- Unprotected sexual contact with an infected person
- Sharing needles, syringes, or drug injection equipment
- Mother passing the virus to her baby during childbirth
- Sharing personal items like razors, toothbrushes, or nail cutters
- Contaminated blood transfusions or unsterilized medical/dental instruments
Many people with Hepatitis B have no symptoms at all in the early stages — this is what makes it dangerous. When symptoms do appear, they may include:
- Extreme tiredness and persistent fatigue
- Yellowing of the skin and eyes (jaundice)
- Dark-coloured urine and clay-coloured stools
- Swollen abdomen due to fluid build-up (ascites)
- Aching joints and muscle pain
- Fever, nausea, and vomiting
Important: If Hepatitis B becomes chronic (lasting more than 6 months), it requires ongoing care from a liver specialist. Long-term antiviral medication can suppress the virus and prevent serious liver damage — but early diagnosis is the key.
- Get vaccinated — Hepatitis B vaccine is safe, very effective, and part of India's national immunization programme
- Always insist on sterile needles and medical equipment
- Practice safe sex with protection
- All pregnant women should be tested for Hepatitis B
- Newborns of infected mothers must receive the vaccine and hepatitis B immunoglobulin (HBIG) within 12 hours of birth
Early blood testing and diagnosis are the most critical steps in managing Hepatitis B and Hepatitis C effectively.
Hepatitis C is caused by the Hepatitis C virus (HCV). Unlike Hepatitis A and B, there is currently no vaccine for it. However, thanks to modern medicine, Hepatitis C is now curable in over 95% of patients using a short course of oral tablets called Direct-Acting Antivirals (DAAs).
The biggest challenge with Hepatitis C is that it is a "silent" disease. Most people have no symptoms for 10 to 20 years, by which time significant liver damage may have already occurred.
- Sharing needles or drug injection equipment (most common route)
- Blood transfusions received before proper screening was introduced
- Unsafe tattooing or body piercing with unsterilized equipment
- Medical or dental procedures using non-sterile instruments
- Rarely through sexual contact (risk is low but real)
- Mother to child at birth (less common)
Most people with chronic Hepatitis C have no obvious symptoms for many years. When the liver becomes severely damaged, symptoms may include:
- Persistent, unexplained fatigue and weakness
- Jaundice — yellowing of the skin and eyes
- Bruising or bleeding more easily than usual
- Swelling in the legs or abdomen
- Confusion or difficulty concentrating (hepatic encephalopathy in advanced cases)
- Spider-like blood vessel patterns visible on the skin
Great news: Hepatitis C treatment has been completely transformed. A simple course of tablets taken for just 8 to 12 weeks can now permanently cure most people of Hepatitis C. The most important step is getting tested so treatment can begin as early as possible.
Use this table to quickly understand the key differences between the three types of viral hepatitis:
| Feature | Hepatitis A | Hepatitis B | Hepatitis C |
|---|---|---|---|
| Caused By | HAV virus | HBV virus | HCV virus |
| Main Transmission | Contaminated food & water | Blood, body fluids, childbirth | Blood-to-blood contact |
| Acute or Chronic | Acute only (short-term) | Can become chronic | Usually chronic (75–85%) |
| Vaccine Available | ✅ Yes (2 doses) | ✅ Yes (3 doses) | ❌ Not yet |
| Curable | Self-resolves naturally | No cure; manageable | ✅ Curable in 95%+ cases |
| Risk of Liver Cancer | None | High (if chronic & untreated) | High (if untreated long-term) |
| Early Symptoms | Jaundice, fever, nausea | Often none — silent | Usually none for years |
| Treatment | Rest, fluids, no alcohol | Long-term antiviral tablets | 8–12 weeks of DAA tablets |
| Common in India | ✅ Very common | ✅ Very common | ✅ Significant burden |
Many liver diseases have no obvious symptoms in the early stages. Do not wait for signs to appear. Consult a gastroenterologist or liver specialist if you:
- Notice yellowing of your skin or the whites of your eyes
- Experience unexplained fatigue lasting more than 2–3 weeks
- Have a family history of Hepatitis B or liver disease
- Have had unprotected sex or shared needles at any point
- Are pregnant and have not been tested for Hepatitis B
- Have dark urine or pale stools without any obvious cause
- Notice swelling in your abdomen or legs that does not go away
- Received a blood transfusion before the year 2000 in India
Remember: Hepatitis B and C are diagnosed with a simple blood test. Early detection can mean the difference between manageable treatment and serious, irreversible liver damage. If you are unsure, get tested — it could save your life.
