[Epidemiological trend in rotavirus infections in children hospitalized in the Department of Paediatrics at Warsaw Bielany Hospital; 2005-2007].
OBJECTIVE
defining the epidemiological trend in community acquired and nosocomial rotavirus infections in children hospitalized in the Department of Paediatrics of the Warsaw Bielany Hospital; 2005-2007. Assessment of the correlation with respect to age, sex and month of the year.


METHODS
we reviewed 1126 case histories of patients age from 1 month to 16 years (median 19 months) admitted to the Hospital because of vomiting and diarrhea. In the period in question these children accounted for 24% of all admissions (1126/4682). We also reviewed 88 histories of children who in the same period acquired nosocomial rotavirus infections. In all the cases stool was examined for rotavirus antigen and bacteria.


RESULTS
we were able to determine the etiology of acute gastroenteritis in only 45% (504/1126) of the admitted cases. Majority of these, 82% (414/504), were rotavirus infections. We noted a slight decrease in the number of community acquired rotavirus infections in the years 2005-2007. Unfortunately we found an increase in the number of nosocomial rotavirus infections from 10 to 23% in the period under review. There was a statistically significant rise in the incidence of rotavirus infections (p<0.001) among children below 5 years of age, 53.5% were children 6- 24-months-old. The incidence was not related to sex. We also observed that the peak of incidence was shifting from winter to summer months.


CONCLUSIONS
we suggest that a broader diagnostic work-up should be carried out on children hospitalized for acute gastroenteritis in order to detect other pathogens.
