Introduction:

Viral hepatitis is a global health problem, causing high mortality and morbidity. Despite advances in the prevention, diagnosis and treatment of hepatitis B, this disease is still a concern of health authorities.

Objective:

Toupdate on current behavior and management of hepatitis B virus infection.

Methods:

A bibliographic review was carried out during April and May 2021, consulting 211 articles in English and Spanish from databases such as SciELO, PubMed, Lilacs and Medigraphic, of which 30 citations were used. The combination of Boolean terms and operators and theoretical methods such as: analysis-synthesis, induction-deduction and historical-logical were used.

Results:

The behavior of the infection caused by the hepatitis B virus was addressed, emphasizing its epidemiology, morphological and functional characteristics that allow its infectivity, evolution and clinical manifestations, complications, treatment and current perspectives.

Conclusions:

The natural history of infection is dynamic, and clinical manifestations depend on various factors. Hepatitis B virus infection can cause complications such as liver cirrhosis and hepatocellular carcinoma, and its main route of transmission is parenterally. The diagnosis is made mainly through serological techniques. Differentiated care for groups at risk is essential and, although there is an effective vaccine, there are still cases and treatments have been developed with positive results.
