[Viral respiratory infections in small children in the season in the season 1996-1997].

Using the immunofluorescence method, the etiology of virus respiratory infection was assayed in children aged 0-2 years, hospitalized because of respiratory diseases in the epidemic season 1996-1997. Data obtained were compared with those from the preceding season (1995-1996), as well as, from the 10 preceding seasons (1985-1995). In the season under study, participation of respiratory viruses was a little higher in the infections to be hospitalized. As compared with the preceding season, and the preceding 10 seasons, infections with parainfluenza type 1 and 3 viruses were higher in statistically significant way. Compared with the preceding seasons, more viral respiratory infections were found in November 96, as well as, in January and February 97. The number of viral respiratory infections was increased among children aged 10-12 months.
