SLIDE 2] Viral Hepatitis: Historical Perspective Before the discovery of hepatitis A virus (HAV) and hepatitis B virus (HBV) during the 1960s and 1970s, patients with viral hepatitis were classified based on epidemiologic studies as having either infectious (transmitted person to person by the fecal-oral route) or serum (transmitted by transfusion of blood products) hepatitis. (cdc.gov)
However, some patients with typical signs and symptoms of viral hepatitis did not have serologic markers of HAV, HBV or HDV infection and were categorized based on epidemiologic characteristics as having either parenterally transmitted non-A, non-B hepatitis or enterically transmitted non-A, non-B hepatitis.
