Where are Hepatitis B and C found in the World?

Maps of the world showing where hepatitis B and C are found more frequently, the colour references are explained below. 

It is important to be tested if you come from a country where hepatitis B or C is common or you have been exposed to needles or surgical instruments that may have been used for other people.

The maps are drawn as a Peters' projection, which accurately represents the actual surface of countries and continents.

    


 

     

There are some differences between hepatitis B and C - for example:

Hepatitis B Hepatitis C
The most common route of infection is during birth from mother to child or in early childhood in countries with medium or high prevalence.


Unprotected sexual contact is the most common route in countries with low prevalence.

The most common route of infection of hepatitis C is through sharing or re-using needles or surgical instruments.

For example injections, blood transfusions or renal dialysis in countries with few resources; or sharing injected drugs.

Transmission at birth and by unprotected sexual contact can also occur but is not common.

The majority of adults that come in contact with Hepatitis B will have a short infection (acute) which resolves after a few weeks. More than half of adults and children that come in contact with hepatitis C virus develop a long term (chronic) infection.
The hepatitis B vaccine protects against infection. There is no vaccine to protect against hepatitis C.
