HEPATITIS B

Hepatitis B is transmitted through perinatal, percutaneous, sexual, and close person-to-person contact, ie by open cuts and sores.

Human hepatitis B virus belongs to the family of Hepadnaviridae of small, enveloped, primarily hepatotropic DNA viruses. The virus replicates in the host and assembles exclusively in the hepatocytes and virions are released non-cytopathically through the cellular secretory pathway.

Chronic hepatitis B is defined as a chronic necroinflammatory liver disease due to persistent hepatitis B virus infection.

Hepatitis D infection is found only in patients with hepatitis B as it requires the hepatitis B outer coat. It is transmitted through sexual and percutaneous (especially IV drug use) routes.

Hepatitis B and D both have an incubation period of 30-180 days.

Antimicrobial resistance has become increasingly dire as the rapid emergence of drug resistance, especially gram-negative pathogens, has outpaced the development of new antibiotics. At a recent virtual symposium, Dr Hsu Li Yang, Vice Dean (Global Health) and Programme Leader (Infectious Diseases), NUS Saw Swee Hock School of Public Health, presented epidemiological data on multidrug-resistant (MDR) gram-negative bacteria (GNB) in Asia, while Dr Tan Thuan Tong, Head and Senior Consultant, Department of Infectious Diseases, Singapore General Hospital (SGH), focused on the role of ceftazidime-avibactam in MDR GNB infections. Dr Andrea Kwa, Assistant Director of Research, Department of Pharmacy, SGH, joined the panel in an interactive fireside chat, to discuss challenges, practical considerations, and solutions in MDR gram-negative infections. This Pfizer-sponsored symposium was chaired by Dr Ng Shin Yi, Head and Senior Consultant of Surgical Intensive Care, SGH.
