[Epidemiological and virological research on influenza and viral respiratory infections in the southeastern region of Romania in the cold season of 1991-1992]

Abstract

Investigations pointed out the high level of respiratory diseases and pneumonias in children, especially in the youngest ones (0-1 year-old) during all the surveyed period. An influenza outbreak during the second half of February was registered in the infantile population--school and low-age children--which gave most of the cases. Serology and isolations incriminated an influenza virus related to the A/Beijing 353/89 (H3N2) strain. Isolations worked out after the influenza epidemics pointed out circulation of parainfluenza and adenoviruses. The necessity is emphasized of the anti-influenza vaccination of low-age children.
