\begin{abstract}
\textbf{Objective:} To evaluate the behavior of the viruses responsible
for acute respiratory infections before (2016-2019) and after
(2020-2021) the start of the circulation of the SARS-CoV-2 virus in
pediatric patients treated at a reference center from Barranquilla,
Colombia. \textbf{Materials and methods:} An observational descriptive
study was carried out, data were obtained reviewing the influenza-like
illness and severe acute respiratory infection database in the pediatric
population of the sentinel surveillance reference center in the district
of Barranquilla during the years 2016 - 2021, applying inclusion and
exclusion criteria. \textbf{Results}: During 2016-2019, the average age
of individuals was 1.3 (\selectlanguage{ngerman}±1.7) years, during 2021 it was 2.3 (±3.5)
years. The distribution by sex was similar, predominantly male. August
and February were the months with the highest record of symptoms for
2016-2019 and 2021, respectively, the most frequent being cough, fever,
shortness of breath, and diarrhea. By 2021 there was higher use of
antibiotics and antivirals reported than in 2016-2019. Most patients
tested negative for viral detection. When comparing the percentage of
viruses detected by age group and years of detection, positivity was
lower in 2021 by every age group, and respiratory Syncytial Virus (RSV)
was the most frequently detected. \textbf{Conclusions:} There was less
virus positivity in viral detection tests in the pediatric population
during 2021. RSV persists as the main etiology affecting this
population, especially infants. The use of antibiotic therapy in viral
infections continues to be a problematic practice in their management.
Sentinel surveillance can be strengthened throughout the country.%
