Hepatitis B virus (HBV) is a partially double-stranded DNA virus, [1] a species of the genus Orthohepadnavirus and a member of the Hepadnaviridae family of viruses. [2][3] This virus causes the disease hepatitis B. [4] Hepatitis B virus is classified in the genus Orthohepadnavirus, which contains 11 other species. [3] .

2020年7月27日 · Chronic infection is diagnosed by a positive test for the surface antigen of HBV (HBsAg). When a person tests positive for HBsAg, an HBV DNA test should also be done to determine how high the viral load is. Those with a high HBV viral load and with raised liver enzymes may need to be put on long-term antiviral treatment for their own health.

Identifies indications for HBV vaccine, describes dosing schedules and administration of vaccines, and management of vaccine nonresponders. Summarizes key aspects of the medical history and physical examination, details the initial laboratory workup and recommended immunizations.

Hepatitis B virus (HBV) is a DNA virus, belonging to the Hepadnaviridae family. It is a partially double-stranded DNA virus with a small viral genome (3.2 kb). Chronic HBV infection remains a global public health problem.

2024年12月11日 · Hepatitis B infection is the most common liver infection globally, caused by the hepatitis B virus (HBV). People from endemic areas, or injection drug users and those with high-risk sexual behaviours, are at an increased risk for infection. Most people are asymptomatic, although some will present...

Hepatitis B virus (HBV) infects more than 300 million people worldwide and is a common cause of liver disease and liver cancer. HBV, a member of the Hepadnaviridae family, is a small DNA virus with unusual features similar to retroviruses. HBV replicates through an RNA intermediate and can integrate into the host genome.

Tenofovir alafenamide, like TDF, is a nucleotide analogue that inhibits reverse transcription of pregenomic RNA to HBV DNA.

2018年6月7日 · Hepatitis B virus (HBV) is a hepatotropic virus that can establish a persistent and chronic infection in humans through immune anergy.

2020年2月26日 · Hepatitis C virus (HCV) and hepatitis B virus (HBV) are the leading causes of liver cancer and overall mortality globally, surpassing malaria and tuberculosis. Linkage to care is estimated to be very poor both in developing countries and in high-income countries, such as the United States, countries in Western Europe, and Japan.
