Pharmacology
The hepatitis A virus belongs to the picornavirus family. It is one of several hepatitis viruses that cause systemic disease with pathology in the liver. The incubation period for hepatitis A averages 28 days (range: 15 to 50 days). The course of hepatitis A infection is extremely variable, ranging from asymptomatic infection to icteric hepatitis and death. The presence of antibodies to HAV confers protection against hepatitis A infection. However, the lowest titer needed to confer protection has not been determined.
