Quick Answer

HAV stands for hepatitis A virus, which causes hepatitis A, a liver infection spread through the fecal-oral route (contaminated food or water). Unlike hepatitis B and C, HAV does not become chronic. Most people recover fully with supportive care, and a safe, effective vaccine is available.

  • Hepatitis A is caused by the hepatitis A virus (HAV).
  • HAV spreads through ingesting microscopic amounts of fecal matter from an infected person.
  • Unlike hepatitis B and C, HAV does not cause long-term liver disease.
  • Symptoms include fatigue, nausea, abdominal pain, and jaundice.
  • A safe and effective vaccine prevents hepatitis A.
  • Good hand hygiene and safe food and water practices reduce risk.

Context Most Pages Skip

Hepatitis A is often overlooked because it does not lead to chronic infection, but it can still cause significant illness. The virus attacks the liver, triggering inflammation that produces symptoms like fever, jaundice, and fatigue. Understanding how HAV differs from other hepatitis viruses is key to prevention. While hepatitis B and C spread through blood or sexual contact, HAV is transmitted when someone unknowingly ingests the virus from contaminated food, water, or surfaces. This distinction shapes public health strategies, from vaccination campaigns to sanitation improvements.
