Acute gastroenteritis (AGE) remains a global public health concern and Nigeria is one of the two countries accounting for 42% of global under-5 deaths attributable to gastroenteritis. This study aimed to determine the prevalence, seasonality, and risk factors of enteric viruses (EVs) in children with AGE in Ogun State, Nigeria. Stool samples collected from children under-5 from three different hospitals between February 2015 and April 2017 were analyzed using molecular methods for the presence of four EVs (group A rotavirus [RVA], norovirus [NoV], human astrovirus [HAstV], and human adenovirus [HAdV]). Among the 175 samples analyzed, 63 (36%) were positive for at least one EV. The most prevalent was HAstV (19.4%), followed by RVA (16.6%), NoV (5.1%), and HAdV (5.1%). Mixed infections were found in 17 cases. No significant association was observed with age, sex, and risk factors. Though not significant, EV prevalence was higher in the dry season. Positive cases (asides HAdV) had no correlation with temperature and/or humidity. This study provides information on the prevalence and seasonal fluctuations of EVs, which will be of value in the effective management of patients and control strategies for viral gastroenteritis in the country.
