It is transmitted mainly through contaminated drinking water. Usually the infection is self-limiting and resolves within 2–6 weeks. Occasionally a serious disease, known as fulminant hepatitis (acute liver failure) develops, and a proportion of people with this disease can die.
According to WHO, every year, there are an estimated 20 million hepatitis E infections worldwide, leading to an estimated 3.3 million symptomatic cases of hepatitis E, and 56,600 hepatitis E-related deaths.
