[1] [2] Hepatitis is acute if it resolves within six months, and chronic if it lasts longer than six months. [1] [6] Acute hepatitis can resolve on its own, progress to chronic hepatitis, or (rarely) result in acute liver failure. [7] Chronic hepatitis may progress to scarring of the liver , liver failure, and liver cancer. [3] [8]

Viral hepatitis is liver inflammation due to a viral infection. [1] [2] It may present in acute form as a recent infection with relatively rapid onset, or in chronic form, typically progressing from a long-lasting asymptomatic condition up to a decompensated hepatic disease and hepatocellular carcinoma (HCC).
Common causes for acute liver failure are paracetamol (acetaminophen) overdose, idiosyncratic reaction to medication (e.g. tetracycline, troglitazone), excessive alcohol consumption (severe alcoholic hepatitis), viral hepatitis (hepatitis A or B—it is extremely uncommon in hepatitis C), acute fatty liver of pregnancy, and idiopathic (without ...
About 40% of all acute viral hepatitis is caused by HAV. [38] Infected individuals are infectious prior to onset of symptoms, roughly 10 days following infection. The virus is resistant to detergent, acid (pH 1), solvents (e.g., ether, chloroform), drying, and temperatures up to 60 °C. It can survive for months in fresh and salt water.
Hepatitis B is an infectious disease caused by the hepatitis B virus (HBV) that affects the liver; [1] [6] it is a type of viral hepatitis. [7] It can cause both acute and chronic infection. [1] Many people have no symptoms during an initial infection.
