Rotavirus gastroenteritis causes significant morbidity and mortality, particularly among children under 5 years of age in low- and middle-income countries. This study aimed to describe the epidemiological and molecular characteristics of rotavirus diarrhea based on sentinel surveillance data from Burkina Faso between 2015 and 2025.
We conducted a descriptive cross-sectional study of sentinel surveillance data on cases of diarrhea among hospitalized children under five years of age. We calculated proportions to describe the characteristics of the cases in terms of time, location, and individual using the Python 3.14 programming language.
A total of 983 cases of rotavirus diarrhea were confirmed among 6,728 suspected cases, representing a confirmation rate of 14.61% across the country’s four sentinel sites. Children under 12 months of age accounted for 53.12% of confirmed cases, and male children accounted for 60%. The case fatality rate was 1.63%, and 20.37% of confirmed cases presented with severe acute dehydration. Additionally, 24.51% of cases older than 6 months suffered from severe acute malnutrition. Most cases were recorded between December and March during the Harmattan season. Genotype G9 reemerged in 2024 and accounted for 68.52% of the identified G genotypes. Strains G1P[8] and G1P[6] accounted for more than 60% of all genotypes combined.
The continued circulation of rotavirus and the reemergence of genotype G9 underscore the need to strengthen virological surveillance. Furthermore, preventive interventions such as public awareness campaigns during the Harmattan season and the strengthening of clinical management are recommended.
