Antibiotic Use Among Children Under Two Years With Respiratory Syncytial Virus Infection at Korle Bu Teaching Hospital, Ghana.

BackgroundRespiratory syncytial virus (RSV) is a major cause of lower respiratory tract infections in children, often leading to hospitalisation in infants. In low-resource settings where routine RSV diagnostics are unavailable, clinical overlap with bacterial pneumonia frequently results in unnecessary antibiotic use, contributing to antimicrobial resistance. ObjectiveTo evaluate the frequency and clinical determinants of antibiotic use among RSV-positive children under two years at a tertiary hospital in Ghana. MethodsThis cross-sectional study was conducted from June to November 2023 at the Department of Child Health, Korle Bu Teaching Hospital. Children with acute respiratory illness were enrolled and tested for RSV using molecular point-of-care and reverse transcriptase-polymerase chain reaction methods. Antibiotic use and clinical characteristics were analysed among RSV-positive cases. ResultsOf 128 children enrolled, 72 (56.2%) tested positive for RSV. Among these, 48 (66.7%) received antibiotics. Antibiotic use was significantly associated with markers of disease severity, including hypoxia (p = 0.009), tachypnea (p = 0.015), dyspnea (p < 0.001), and hospital admission (p < 0.001). Only 11 (23%) had suspected or confirmed bacterial co-infections. ConclusionA substantial proportion of RSV-positive children received antibiotics. These findings underscore the importance of antimicrobial stewardship programs, rapid diagnostics, and preventive interventions, such as maternal RSV vaccination. Strengthening diagnostic capacity and clinical decision-making in pediatric care is crucial for reducing inappropriate antibiotic use and addressing antimicrobial resistance in low-resource settings.
