[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]
Globally, around 1.4 million symptomatic cases occur each year [1] and about 114 million infections (symptomatic and asymptomatic). [5] It is more common in regions of the world with poor sanitation and not enough safe water. [14] In the developing world, about 90% of children have been infected by age 10, thus are immune by adulthood. [14]
Hepatitis A and hepatitis B can be prevented by vaccination. Effective treatments for hepatitis C are available but costly. [6] In 2013, about 1.5 million people died from viral hepatitis, most commonly due to hepatitis B and C. [6] East Asia, in particular Mongolia, is the region most affected. [6]
