The frequency of rotavirus, enteric adenovirus and norovirus in children with acute diarrhea

adenoviruses) that have been reported as a cause of nonbacterial acute gastroenteritis. This study aims to determine the prevalence and the distribution of viruses responsible for gastroenteritidis in children.Methods: A epidemiological study on common diarrheal viruses was conducted in Afyon City, Turkey between January and December 2009. One hundred and fifty faecal samples from children under 6 years of age(mean age, 2.18±SD 1.64 years, range: 1 ? 72 months)(negative for the presence of pathogenic bacteria by standard culture methods) were tested by ELISA(Ridascreen and Biomeriux) and RT PCR methods for detection of rotavirus.Results: Noroviruses were detected in 22.8% of 92 children (<6 years of age) and rotavirus were detected in 40 % of 150 hospitalized for gastroenteritis in Afyonkarahisar, Turkey, during 2009; rotaviruses were detected in 15.8 % in 95 children with RT PCR. Of children with viral enteritis, 6,5% had a mixed norovirus-rotavirus infection. The frequency of adenovirus were 6 of 122 patients(4.91%). Adenovirus plus rotavirus positivity with one case, Rotavirus plus Nörovirus draw in four samples were found.Conclusions: Rotavirus is still the most common cause for gastroenteritis. Norovirus may be agent in patient with vomiting prominent. The severity of infection was lower for norovirus than for rotavirus but increased in co-infection.
