Every year on July 28, the world observes World Hepatitis Day, raising awareness of viral hepatitis — an often misunderstood and underdiagnosed group of diseases that affect the liver.

While many have heard of hepatitis A, B or C, there are five distinct types: A, B, C, D and E. Each has its own cause, method of transmission and treatment options. Understanding the differences can help you protect yourself, get screened and seek the right care if needed.

What Is Hepatitis?

Hepatitis means inflammation of the liver, often caused by viruses — but it can also be triggered by alcohol, toxins, medications or autoimmune conditions. When we talk about viral hepatitis, we refer to five major strains: A, B, C, D and E.

Hepatitis A (HAV): Short-Term, Fecal-Oral Spread

• Transmission: Through contaminated food, water or close contact in poor sanitation settings.
• Symptoms: Jaundice, nausea, stomach pain, fatigue, dark urine.
• Duration: Acute (short term); doesn’t lead to chronic disease.
• Prevention: Highly effective vaccine; good handwashing and food safety.
• Treatment: No specific treatment needed — most recover fully.

Hepatitis B (HBV): Can Be Chronic

• Transmission: Blood, semen, vaginal fluids; sex, childbirth or sharing needles.
• Symptoms: Fatigue, joint pain, jaundice — though many have no symptoms.
• Risk: Chronic infection can lead to cirrhosis or liver cancer.
• Prevention: Vaccine available and part of routine immunization.
• Treatment: Antiviral meds can control chronic cases, but there’s no cure yet.

Hepatitis C (HCV): Silent but Curable

• Transmission: Mainly through blood — commonly from shared needles or unscreened transfusions before 1992.
• Symptoms: Often none until liver damage is severe.
• Risk: High chance of becoming chronic and leading to cirrhosis, liver failure or cancer.
• Prevention: No vaccine yet, so harm reduction and screening are vital.
• Treatment: Curable in over 95% of cases with modern antiviral meds.

Hepatitis D (HDV): Only With Hepatitis B

• Transmission: Through blood or bodily fluids, but only infects people who already have hepatitis B.
• Symptoms: More severe liver disease than B alone.
• Risk: Rapid progression to cirrhosis or liver cancer.
• Prevention: HBV vaccination also protects against HDV.
• Treatment: No specific treatment; some antivirals may help.

Hepatitis E (HEV): Often Linked to Contaminated Water

• Transmission: Mainly through fecal-contaminated drinking water, especially in developing countries.
• Symptoms: Similar to hepatitis A (fatigue, jaundice, nausea).
• Risk: Usually mild, but dangerous in pregnant women.
• Prevention: Improved sanitation and clean water access.
• Treatment: No vaccine in most countries; usually resolves on its own.

Why Awareness Matters

Most people with hepatitis B or C don’t even know they have it, which puts them at risk for serious complications. Early detection saves lives — and for many types, prevention is as simple as a vaccine or hygiene measures.

Prevention Tips for All Types

• Get vaccinated for hepatitis A and B.
• Avoid sharing needles or personal items like razors or toothbrushes.
• Wash hands thoroughly, especially when traveling.
• Practice safe sex.
• Use clean water and ensure proper food hygiene.

Viral hepatitis is a serious yet often preventable group of diseases that affect millions of people worldwide. Whether it's hepatitis A through food and water, hepatitis B and C through blood, or the lesser-known D and E types, each carries unique risks — but also paths for prevention, screening and treatment. Staying informed, getting vaccinated when possible and practicing safe habits can make all the difference in protecting your liver and long-term health. On World Hepatitis Day, take a moment to learn your status and share this knowledge — it could save a life.
