Understanding of transmission of viral hepatitis continues to improve. Patients with certain behaviors (eg, injecting drug use, male homosexual activity) are at risk of infection with multiple hepatitis viruses. However, a significant proportion of patients who become infected have no identifiable risk factor for hepatitis. Many who contract hepatitis B or C are unaware of their infection. Therefore, patients often present with serologic evidence of previous infection but have no knowledge of a previous infection or recognizable risk factors.
