Hepatitis is liver inflammation caused by viruses, alcohol, or drugs. Hepatitis A spreads fecal-orally and is prevented by vaccine. Hepatitis B transmits via blood, sex, or perinatally; vaccines prevent it and antivirals can suppress chronic infection, though no universal cure exists. Hepatitis C transmits mainly through blood and is now curable for most people with direct-acting antivirals. Blood screening, safer practices, and harm-reduction services have reduced transmission. Testing and access to prevention and treatment are essential.

Hepatitis is liver inflammation, not a single virus

"Hepatitis" describes inflammation of the liver. Multiple things can inflame the liver: viruses, alcohol, certain medications, and some metabolic conditions. The result ranges from mild, short-lived illness to chronic disease that damages the liver over years.

The common viral types and how they differ

Hepatitis A

Hepatitis A spreads by the fecal-oral route - contaminated food, water, or close personal contact are the usual sources. It typically causes an acute illness and does not become chronic. A safe, effective vaccine prevents infection.

Hepatitis B

Hepatitis B spreads through blood, sexual contact, and from mother to baby around the time of birth. It can cause both acute and chronic infection. There is currently no universally available cure for chronic hepatitis B, but effective antiviral drugs suppress the virus and reduce liver damage. A highly effective vaccine prevents most infections.

Hepatitis C

Hepatitis C transmits mainly through blood exposure (for example, shared needles). It often causes chronic infection if untreated. In the last decade direct-acting antiviral (DAA) medicines have transformed care: most people treated with DAAs are cured of hepatitis C.

Why transfusion risk is lower now

Blood supplies in many countries are screened for viral hepatitis and other infections. That screening has dramatically reduced the risk of acquiring hepatitis from transfusions, though risks still exist where resources or screening are limited.

Non-viral causes matter too

Alcohol-related hepatitis and drug-induced liver injury are common noninfectious causes. Long-term heavy alcohol use can cause inflammation, fatty liver, fibrosis, and cirrhosis. Several prescription and over-the-counter drugs can damage the liver, especially when combined with alcohol or taken at high doses.

Prevention and testing

Prevention strategies depend on the cause: vaccines for hepatitis A and B, safer sex practices, clean-needle programs and harm reduction to prevent blood-borne transmission, careful food and water hygiene to prevent hepatitis A, moderation of alcohol, and cautious use of medications. Testing matters because viral hepatitis can be asymptomatic for years; early diagnosis enables prevention of complications and access to treatment.

Stigma and access

Hepatitis has carried social stigma, which can discourage people from getting tested or treated. Public health approaches that expand vaccination, offer accessible testing, support harm-reduction services, and make antiviral treatments available reduce both transmission and stigma.

Bottom line

Hepatitis is an inflammatory condition of the liver with many causes. Vaccines, safer medical practices, harm-reduction programs, and modern antiviral medicines have changed outcomes in recent years. Prevention, testing, and timely care remain the most effective tools.

FAQs about Hepatitus

Can hepatitis be prevented?
Yes. Vaccines prevent hepatitis A and B. Safer sex, clean-needle programs, good food and water hygiene, and screened blood supplies also reduce transmission.
Is hepatitis B curable?
There is no widely available cure for chronic hepatitis B, but effective antiviral drugs can suppress the virus and reduce liver damage. Vaccination prevents most new infections.
Is hepatitis C still dangerous?
Hepatitis C can cause chronic liver disease if untreated, but direct-acting antiviral medicines now cure most people who receive treatment.
Can alcohol cause hepatitis?
Yes. Heavy or prolonged alcohol use can inflame the liver and lead to fatty liver, hepatitis, fibrosis, or cirrhosis.
Should I get tested even if I feel fine?
Yes. Viral hepatitis can be asymptomatic for years. Testing is important so you can get treatment if needed and prevent transmission to others.
