ABSTRACT
Rotavirus remains the most common cause of severe childhood diarrhea worldwide and of diarrheal mortality in developing countries. Despite the efforts made by the government of Rwanda and the stakeholders to reduce children mortality; the prevalence of rotavirus among under five children in Rwanda remains to be determined. We conducted a hospital-based cross-sectional study that aimed at determining the prevalence of rotavirus infection in under fie children presenting with gastroenteritis in eight hospitals in Rwanda. From June 2013 and August 2014 we collected and tested stool samples for the presence ofrotavirus using an enzyme immunoassay and a Real Time-Polymerase Chain Reaction for genotyping. In 969 stool samples; 232 (23.94 and 5.1) while the lowest one was observed in March (0.00). Muhima Hospital had the highest prevalence (33.33) whereas Kabgayi and Rwamagana Hospitals had the lowest (15.62 and 18.18; respectively). Male children were more affected than females (25.8 versus 21.5). We found that the prevalence was higher (31.10) in children aged between 12 and 24 months than in other age groups. For genotyping; G9 [P8] was the most prevalent genotype as G9 prevalence was 54.6 whereas [P8] prevalence was 73.9.In conclusion; the prevalence of rotavirus gastroenteritis was high among children aged less than 5 years; and it was different according to age groups and among different hospitals
