Hepatitis B, Singapore - Shim Clinic

Hepatitis B Singapore: Hepatitis B is an infection of the liver caused by the Hepatitis B virus.

Hepatitis B infection is caused by the Hepatitis B virus and is usually screened for by detecting HBsAg in the blood. Immunity may be discerned by detecting HBsAb, and if absent, the Hepatitis B vaccine or Twinrix® vaccine may be given.

  • The hepatitis B virus is 100 times more infectious than HIV, the virus that causes AIDS, and infects about 10 times more people than HIV worldwide.
  • Hepatitis B virus infects the liver, and more than 350 million people in the world are lifelong hepatitis B virus carriers.
  • Long-term hepatitis B virus infection causes at least one million premature deaths every year from cirrhosis of the liver or liver cancer. It is second only to tobacco as the leading cause of cancer in humans.
  • Among the Hepatitis B carriers, 25% will develop serious liver diseases, including chronic hepatitis, cirrhosis, and hepatocellular carcinoma.
  • The hepatitis B virus can be passed from an infected mother to her baby during childbirth, 1 in 20 Singaporeans are chronically infected with hepatitis B virus.

(Elsevier) Chronic hepatitis B virus (HBV) can progress to cirrhosis and hepatocellular carcinoma (HCC). A study published in The Journal of Molecular Diagnostics describes a new HBV assay that offers advantages over currently used methods because it has the capability to detect closed circular DNA (cccDNA) in serum, single cells, and preserved tissue samples. This assay can be used to diagnose HCC at an earlier stage to manage treatment more effectively. (Source: EurekAlert! - Medicine and Health)
