Quick Answer

Hepatitis viruses are a group of five distinct viruses (A, B, C, D, E) that cause liver inflammation. Hepatitis A spreads through contaminated food or water, while hepatitis B and C are transmitted via blood or sexual contact. Hepatitis D only infects those with hepatitis B, and hepatitis E is similar to A. Chronic hepatitis B and C can lead to serious liver damage over time.

  • Hepatitis A and E are typically acute and do not become chronic.
  • Hepatitis B and C can become chronic infections lasting years.
  • Hepatitis D requires co-infection with hepatitis B to replicate.
  • There are at least six major genotypes of hepatitis C, which affect treatment choice.
  • Hepatitis viruses are classified by transmission route and whether they cause acute or chronic disease.
  • Vaccines exist for hepatitis A and B, but not for C.

The term 'hepatitis' means liver inflammation, and these viruses are the most common cause worldwide. Knowing which virus you are dealing with is crucial because prevention, testing, and treatment vary greatly. For example, hepatitis A is usually a short-term illness spread through contaminated food, while hepatitis B and C can persist for decades without symptoms, silently damaging the liver. This guide explains the key differences among the five hepatitis viruses, including how they are transmitted, their typical course, and what to expect from testing and treatment.
