Abstract

Two billion people, or one in three, have been infected with hepatitis B worldwide. Of these, about 260 million live with chronic hepatitis B. Each year about 900,000 people die from hepatitis B worldwide, and about 2,000 of these deaths occur in the United States. Hepatitis B is transmitted through blood and is 100 times more infectious than HIV. An estimated one billion infectious viruses are in one-fifth of a teaspoon of blood of an infected person, so exposure to even a minute amount, such as on a shared toothbrush can cause infection. Hepatitis B is sometimes referred to as the “silent epidemic” because most people who are infected do not experience any symptoms. Liver cancer is the fourth leading cause of cancer deaths throughout the world, behind lung, colorectal and stomach cancers. Almost half of liver cancers are caused by chronic infection with hepatitis B. The World Health Organization (WHO) recommends the inclusion of hepatitis B vaccine in immunization programs of all countries; in 2017, about 8 of 10 infants born throughout the world received three doses of hepatitis B vaccine.
