Hepatitis B is more common in some parts of the world than others. In China and other parts of Asia up to10% of the population may be chronically infected. In Europe and the Middle East the number of chronic hepatitis B cases is approximately 10 million,with nearly 1 million new infections each year in Europe
In fact, 2 billion people have been exposed to the hepatitis B virus around the world.About 90% of them have the acute form of the disease from which they will fully recover. However, some 400 million people worldwide are chronically infected with hepatitis B, which means they may have it for the rest of their lives. More than 600,000 people worldwide die from the disease every year.
In areas like North America and Western Europe, a smaller percentage of the population is infected with the hepatitis B virus. This is because most people in these areas are given a hepatitis B vaccine against the virus at birth
