Hepatitis E virus (HEV) is mostly transmitted through consumption of contaminated water or food. HEV is a common cause of hepatitis outbreaks in developing parts of the world and is increasingly recognized as an important cause of disease in developed countries.Safe and effective vaccines to prevent HEV infection have been developed but are not widely available.epatitis viruses are the most common cause of hepatitis in the world but other infections, toxic substances (e.g. alcohol, certain drugs), and autoimmune diseases can also cause hepatitis.

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.nprotected 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.

Hepatitis A (formerly known as infectious hepatitis) is an acute infectious disease of the liver caused by the hepatitis A virus (HAV).Many cases have few or no symptoms, especially in the young. The time between infection and symptoms, in those who develop them, is between two and six weeks.n the developing world, about 90% of children have been infected by age 10, thus are immune by adulthood. It often occurs in outbreaks in moderately developed countries where children are not exposed when young and vaccination is not widespread. In 2010, acute hepatitis A resulted in 102,000 deaths.
