Hepatitis A (infectious jaundice) is caused by Hepatitis A Virus (HAV), a picornavirus transmitted by the fecal-oral route often associated with ingestion of contaminated food. It causes an acute form of hepatitis and does not have a chronic stage. The patient's immune system makes antibodies against HAV that confer immunity against future infection. People with hepatitis A are advised to rest, stay hydrated and avoid alcohol. Hepatitis A can be spread through personal contact, consumption of raw sea food or drinking contaminated water.
