[Studies of the influenza epidemic of January-March, 1974].
In an epidemiologic, clinical and viral study of several influenza foci in some urban districts of Romania during January-March 1974, 23 influenza virus B Hong-Kong 8/73 strains were isolated. The dynamics of HAI serum antibodies confirmed the viral diagnosis. The epidemic ran a slow course, affecting especially the 14-25 years age group and had an evident benign clinical aspect.
