General Information

Hepatitis A virus is a small, non-encapsulated virus that belongs to the Picornavirus family and the Hepatovirus genus. It is represented by a single-stranded RNA genome and a capsid.

The virus is mainly transmitted through the fecal-oral route, through contaminated water and food.

The incubation period of the disease is up to 28 days (on average 15-60 days). Developed hepatitis is of moderate severity, although complications may develop. Hepatitis A virus does not persist in the body and does not give a chronic form.

The virus is present in the blood and feces 2 weeks before the clinical development of the disease and 2 weeks after the onset of jaundice.

Routine diagnostics of infection is based on serology. The first antibodies that appear in the blood immediately after the development of ARIS anti-HAV-IgM symptoms reach a maximum in one month and reverse in 6 months. IgG appears about 2 weeks after the acute period. The presence of IgG confirms past infection or the presence of immunity to hepatitis A.
