Research on viral hepatitis performed in the "Stefan S. Nicolau" Institute of Virology.
The first phase of research on viral hepatitis (VH) performed in the Institute of Virology (1949--1967) consisted of etiopathogenic, clinico-epidemiological and histopathological investigations which outlined the concepts of VH plurietiology,  of infravirus, as well as the characteristic symptomatic triad, the "age group" phenomenon, the clinico-morphological characteristics of sclerogenous hepatitis. The 2nd research phase was mainly devoted to the study of the distribution, properties and clinico-epidemiological correlations of HBsAg. The application of a modern methodology confirmed many of the previously obtained results.
