Hepatitis B surface antigen (HBsAg), derived from the viral envelope, is the first antigen to appear following infection and can be detected serologically as an aid in the laboratory diagnosis of acute HBV infection.

WebOnce inside the host, HBV is transported in the blood to the liver, where it infects liver cells. The incubation period of acute HBV infection is usually about 75 days, but can range from 45 to 200 days. The virus spreads in the liver and causes a spectrum of disease, ranging from acute hepatitis to chronic liver disease and liver tumours. WebA.
