Studies concerning the course of some acute respiratory diseases in nine districts of south-east area of Romania between November 1994 and April 1995. Epidemiological, virological and serological data.
A moderate level of morbidity through acute respiratory diseases (ARD), of the upper tract, viral pneumonia and clinical influenza was recorded during November 1994 and April 1995 in the South-East area of Romania (nine districts). By virological and serological investigation adenosyncytial respiratory, parainfluenza type 3 and influenza type B viruses were found to be the most frequent etiological agents of these infections which affected especially the babies and the children of 1-14 years of age. Sporadic influenza outbreaks were noticed from which influenza strains of virus were isolated, antigenically related to the prototype strain A/Johannesburg 33/94.
