ABSTRACT
Acute diarrhea is one of the leading causes of worldwide mortality and morbidity; four millions annual deaths. The aim of this study is to investigate the prevalence of rotavirus and adenovirus among children with acute diarrhea and to evaluate their clinical and laboratory findings. 199 children aged 1 to 168 months with acute diarrhea were studied in "Mofid" Children Hospital for a one year period. Clinical and laboratory findings including stool culture and WBC and RBC counts in their stool samples were analyzed. From 199 children with diarrhea, 14 cases [7%] were positive for viruses; 11 [5.5%] rotaviruses and 3[1.5%] adenoviruses. In Rotavirus and adenovirus, male to female ratio were 1.2/1 and 2/1, and the mean age were 40.8 and 20.4 months, respectively. Clinical findings comprised frequency, dehydration, fever, vomiting and watery diarrhea. Stool culture was negative and no RBC and WBC were detected. High prevalence of rotavirus and adenovirus in former studies and low prevalence of rotavirus in this study seems to be caused by the diagnostic method we used. Since a fast laboratory process is necessary for immunochromatography, other methods as EIA and PCR are recommended
