Hepatitis A
Fact sheet N°328
Updated July 2013
Key facts
Hepatitis A is a viral liver disease that can cause mild to severe illness.
Globally, there are an estimated 1.4 million cases of hepatitis A every year.
The hepatitis A virus is transmitted through ingestion of contaminated food and water, or through direct contact with an infectious person.
Hepatitis A is associated with a lack of safe water and poor sanitation.
Epidemics can be explosive in growth and cause significant economic losses.
Improved sanitation and the hepatitis A vaccine are the most effective ways to combat the disease.
Hepatitis B
Fact sheet N°204
Updated July 2013
Key facts
Hepatitis B is a viral infection that attacks the liver and can cause both acute and chronic disease.
The virus is transmitted through contact with the blood or other body fluids of an infected person.
About 600 000 people die every year due to the consequences of hepatitis B.
Hepatitis B is an important occupational hazard for health workers.
Hepatitis B is preventable with the currently available safe and effective vaccine.
Hepatitis C
Fact sheet N°164
Updated July 2013
Key facts
Hepatitis C is a liver disease caused by the hepatitis C virus.
The disease can range in severity from a mild illness lasting a few weeks to a serious, lifelong condition that can lead to cirrhosis of the liver or liver cancer.
The hepatitis C virus is transmitted through contact with the blood of an infected person.
About 150 million people are chronically infected with hepatitis C virus, and more than 350 000 people die every year from hepatitis C-related liver diseases.
Hepatitis C can be treated using antiviral medicines.
There is currently no vaccine for hepatitis C; however, research in this area is ongoing.
Hepatitis D
Hepatitis Delta - an introduction
Hepatitis is a general term meaning inflammation of the liver and can be caused by a variety of different viruses such as hepatitis A, B, C, D and E. Since the development of jaundice is a characteristic feature of liver disease, a correct diagnosis can only be made by testing patients' sera for the presence of specific antigens and anti-viral antibodies.
Hepatitis E
Fact sheet N°280
Updated July 2013
Key facts
Every year there are 20 million hepatitis E infections, over three million acute cases of hepatitis E, and 57 000 hepatitis E-related deaths.
Hepatitis E is usually self-limiting but may develop into fulminant hepatitis (acute liver failure).
The hepatitis E virus is transmitted via the faecal-oral route, principally via contaminated water.
Hepatitis E is found worldwide, but the prevalence is highest in East and South Asia.
China has produced and licensed the first vaccine to prevent hepatitis E virus infection, although it is not yet available globally.
