==Hepatitis B==
(詳細はliver and causes an inflammation called hepatitis. It is a DNA virus and one of many unrelated viruses that cause viral hepatitis. The disease, originally known as "serum hepatitis", has caused epidemics in parts of Asia and Africa, and it is endemic in China. About a third of the world's population, more than 2 billion people, have been infected with the hepatitis B virus.〔(WHO | Hepatitis B )〕 This includes 350 million chronic carriers of the virus.〔(FAQ about Hepatitis B ), Stanford University School of Medicine〕 The acute illness causes liver inflammation, vomiting and jaundice. The infection is preventable by vaccination.
Transmission of hepatitis B results from exposure to infectious blood or body fluids containing blood. Possible forms of transmission include (but are not limited to) unprotected sexual contact, blood transfusions, re-use of contaminated needles & syringes, and vertical transmission from mother to child during childbirth. HBV can be transmitted between family members within households, possibly by contact of nonintact skin or mucous membrane with secretions or saliva containing HBV. However, at least 30% of reported cases of hepatitis B among adults cannot be associated with an identifiable risk factor.
