Introduction: Human respiratory syncytial virus (RSV) is the most common respiratory infectious agent in epidemics. It primarily affects children under 5 years of age, and mortality ranges from 0.5% to 1.5% of hospitalized patients. The objective of this study was to evaluate RSV circulation from 2022 to 2024 by describing confirmed cases in patients admitted to a referral hospital. Materials and methods: A retrospective, cross-sectional, descriptive study was conducted on patients with respiratory symptoms who were treated between 2022 and the first six months of 2024 and tested positive for RSV. Results: Of 1246 viral panel tests [filmArray], 253 samples were positive for RSV, identifying a prevalence of 20.3%. The highest frequency was observed in males (56.1%), and the most affected age group was 0 to 5 years. Of all cases, 2022 had the highest number of reported cases, with an average of 66.40% occurring between July and September. The mortality rate in this study was 0.40%. Discussion: In the Orinoquia region, the rainy seasons occur from April to August. Before the pandemic, RSV cases were peaking in upper respiratory infections. However, a considerable decrease has been observed since the pandemic. This may be due to the improved hand hygiene practices implemented as a result of the COVID-19 pandemic.
