Hepatitis B

Abstract

Hepatitis B remains a major public health problem around the world. The discovery of the hepatitis C virus has diverted interest from hepatitis B to this new virus and the epidemic associated with it, but hepatitis B remains a significant pathogen for millions of people worldwide. The World Health Organization has suggested that universal vaccination of children against hepatitis B should be implemented in an attempt to reduce the enormous morbidity and mortality associated with infection of this virus group. The review seeks to identify all the newer discoveries relating to hepatitis B that have been made in the past decade. Reference is made to the appearance of hepatitis B mutants which are able to infect patients previously infected with the wild strain of the virus. The implications of mutants on vaccination programmes is raised, as are issues relating to treatment of hepatitis B infection.
