[Recent acquisitions on viral hepatitis].
In the last years the research on viral hepatitis let to better understand the biological, molecular, immunological and epidemiologic characteristics of the viruses that are responsible for hepatitis. The first studied virus was hepatitis B virus (HBv). The scientific attention is still, today, focused on that virus since new markers of infectivity and biological importance in early diagnosis and in disease evolution have been found. The most important result in the last years in the field of viral hepatitis has been, however, the identification of agents responsible for Non-A-Non-B hepatitis. Its epidemiology and clinical importance are discussed in the present paper. Virus C is the most important parenteral agent of NANB hepatitis. Its epidemiology in at risk populations and its role in post-transfusional and cryptogenetic hepatitis are here discussed. The research of new markers of HCV infection is today considered a main goal since the role of the only marker now available is still under discussion.
