Frequency and seasonal distribution of rotavirus and adenovirus in patients with acute gastroenteritis

Aims The aim of this study was to retrospectively determine the frequency of rotavirus and adenovirus and the distribution of these pathogens by age groups, gender and season in patients admitted to our hospital with gastroenteritis symptoms. Materials and Methods A total of 32755 stool samples collected from patients with gastroenteritis symptoms in the Medical Microbiology Clinic of the Hospital between January 1 and December 31, 2022 were evaluated retrospectively for rotavirus and adenovirus antigens. Rotavirus and adenovirus antigens were analyzed with the Rapid Cassette Test (Microcult, Biotech) kit. In addition, the distribution of pathogens by age groups, gender and season were examined. Statistical analysis was performed using Jamovi® version 2.3.21. Results Antigen test was positive in 9.9% of 32755 stool samples evaluated in our study. Rotavirus was detected in 8.4% and adenovirus in 1.5% of antigen positive samples. Both rotavirus and adenovirus antigen positivity were found to be statistically significantly higher in 0-1 and 2-3 age groups compared to other age groups (p
