Epidemiologic particularities of influenza in 1986 in a large urban centre of Romania.

The study presents the evolutive peculiarities of the epidemiologic influenza process in 1986 in a large urban centre in Romania, inferrable from the active control by a complex methodology based on clinical, epidemiologic and laboratory investigations. The prevalent part of A (H1N1 and H3N2) and B influenza viruses in causing seasonal morbidity risings is being stressed. A (H3N2) and B influenza viruses determined an epidemic rising during the first trimester and A (H1N1) and A (H3N2) during the fourth trimester in 1986.

In further investigations on the evolutive trends of the epidemiologic streptococcal process, an extensive epidemiological survey was carried out in prescholar and school communities in the town of Bucharest with a view to applying efficient antiepidemic measures able to limit primary streptococcal infections and prevent late, redoubtable complications. In 1980, in Bucharest, morbidity from scarlet fever was at its lowest level (92.7 per 100,000) during the last 31 years; it was in general benign, affecting especially in the month of March the 5-9 years age group (623.
