Fast facts about Hepatitis B
and Hepatitis C

HEPATITIS B (HBV)

  • Globally, 2 billion people have been
    infected with hepatitis B virus, with an
    estimated 600,000 dying each year due to
    its acute or chronic consequences
  • Of those who are infected, more than 350
    million have chronic (lifelong) infection and
    75% live in Asia
  • Liver cancer caused by hepatitis B is among
    the first three causes of cancer deaths in
    men, and a major cause of cancer in women
  • Hepatitis B is endemic in China and other
    parts of Asia. Most people in the region
    become infected with HBV during
    childhood and in many areas in the region,
    8% to 10% of the adult population are
    chronically infected
  • Hepatitis B is preventable with a safe and
    effective vaccine, the first vaccine against a
    major human cancer. The vaccine against
    hepatitis B has been available since 1982.
  • The hepatitis B vaccine is 95% effective in
    preventing HBV infection and its chronic
    consequences but is ineffective for those
    who are already infected
  • If infected during childhood, 90% of infants
    and 30% of children will develop chronic
    hepatitis
  • Hepatitis B often goes undetected as
    people often feel well even though liver
    damage is occurring. Late diagnosis of
    chronic hepatitis B with existing liver cancer
    is not uncommon.
  • People with chronic hepatitis B should seek
    regular monitoring. Treatment is
    recommended only at particular stages of
    the disease, to reduce the level of virus in
    the blood and the consequent risk of
    progression to liver disease
  • If left untreated, about 25% of adults who
    are chronically infected from childhood will
    develop liver cancer or cirrhosis (scarring of
    the liver) caused by the chronic infection
  • The hepatitis B virus is 50 to 100 times more
    infectious than HIV
  • Hepatitis B virus is a significant occupational
    hazard for health workers.

 

HEPATITIS C (HCV)

  • Around 3–4 million people worldwide
    become infected with hepatitis C each year,
    with more than 350 000 dying from
    HCV-related liver diseases. Around 2 million
    of these infections each year are
    attributable to unsafe injection practices
  • Some 130–170 million people are
    chronically infected with HCV and at risk of
    developing liver cirrhosis and/or liver
    cancer
  • Statistics show that 60–70% of
    chronically-infected persons develop
    chronic liver disease: 5-20% develop
    cirrhosis, and 1–5% die from cirrhosis or
    liver cancer
  • The virus is most commonly transmitted
    through exposure to infectious blood such
    as through: receipt of contaminated blood
    transfusions, blood products, and organ
    transplants; injections given with
    contaminated syringes, needle-stick injuries
    in health-care settings; injection drug use;
    being born to an HCV-infected mother. It is
    less commonly transmitted through sex
    with an infected person and sharing of
    personal items contaminated with
    infectious blood.
  • The first stage of acute infection is often
    very mild, and may go unnoticed. As
    symptoms are often slow to develop, many
    people are not diagnosed until years, or
    even decades after their initial exposure to
    the hepatitis C virus
  • There is no vaccine for hepatitis C but
    approximately 80% of Asian patients who
    are able to complete recommended
    treatment, are cured
  • The number of people with chronic
    hepatitis C and more advanced liver disease
    or cirrhosis, is projected to
    increase by 38%
    between 2006 and 2015 unless the number
    of people being treated increases
    substantially.
