Résumé

Introduction: Severe acute respiratory infections caused by influenza viruses are a real public health problem. Objective: To study severe acute respiratory infections due to the influenza virus in the pediatric department of CHU-BOGODOGO from January 25, 2023 to December 25, 2023. Methodology: This is a cross-sectional study with descriptive and analytical aims conducted from January 25, 2023 to December 25, 2023. All patients aged under 15 meeting the definition of SARI according to the WHO were included. The Chi-square test with a significance threshold (p-value <0.05) was used to determine the factors associated with the occurrence of influenza virus infection. Results: Of the 142 patients who presented with SARI, 11 patients tested positive for influenza virus, representing a prevalence of 7.7%. Of these, 81.8% were subtyped as influenza A (H1N1) pdm09 and 18.2% as influenza B victoria. The 12–59 month age group was the most represented, accounting for 63.6% of cases, with an average age of 35.45 months. Males predominated, with a sex ratio of 1.8. Almost all patients (90.9%) resided in the city of Ouagadougou. The average time to consultation was 4.27 days. The main clinical symptoms were cough/cold (100%), respiratory distress (36.4%), and fever (18.2%). Chest X-rays were performed in 62.7% of patients due to their accessibility. The majority of patients (81.8%) with influenza virus received antibiotic treatment. The average length of hospital stay was 7.9 days. There were no deaths. In the bivariate analysis, no factor was significantly associated with the influenza virus PCR result. Conclusion: Infection due to the influenza virus is present in children with a relatively low prevalence.
