[Viral respiratory infections detected in small children in 1995-1996]. / Wirusowe zakazenia dróg oddechowych u malych dzieci w sezonie 1995-1996.

As in previous studies we used the fluorescent antibody technique to determine the aetiology of viral respiratory infections in small children who were hospitalized in the epidemic season 1995-96. Data obtained from this study were compared with the results from the previous season (1994-95) and with the results from preceding ten seasons (1985-95). No variation in aetiology of infections was found although a higher occurrence of adenoviruses was uncovered amongst the 1995-1996 group. The monthly rates of morbidity in this same group were highest in November and in April. Data from this season displayed the greatest incidence of morbidity among children from one to six months old. The importance of bread feeding as a measure of prevention against viral respiratory infections was confirmed.

[The occurrence of viral respiratory tract infections in small children in the season 1993-1994 (with reference to the role of breast feeding)]. / Wystepowanie wirusowych zakazen dróg oddechowych u malych dzieci w sezonie 1993-1994 (z uwzglednieniem wplywu karmienia naturalnego).

In the period October 1993 to June 1994, 231 hospitalized children under 2 years of age were examined by immunofluorescence for respiratory viruses. In 114 (49.9%) cases viral etiology was established. The data were compared with results obtained from the season 1992-93. RS virus was predominant as in the previous season but infections of parainfluenzae type 3 virus were rather rare (p < 0.005). Mixed and adenovirus (p < 0.02%) infections were more frequent than in the past season. A breast-fed children were statistical more rarely infected by respiratory viruses (p < 0.05), (RS virus-p < 0.1), than artificial-fed ones.
