The epidemiology of respiratory viruses was analyzed by comparing the pre\u2010 and post\u2010COVID\u201019 periods to assess disruptions in seasonal patterns, changes in virus prevalence, and the affected age groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Our database effectively captured the epidemiology of respiratory infections across the island, as demonstrated by its strong correlation with the number of consultations for ARI. Post\u2010COVID\u201019, the influenza virus exhibited multiple epidemic waves within a single year, deviating from its traditional single annual peak and showing a significant decline in circulation from 2020 to 2023. The circulation of respiratory syncytial virus was also impacted post\u2010COVID\u201019, with epidemics starting earlier and lasting longer compared with pre\u2010COVID\u201019 years. Human rhinovirus circulated more prominently in the post\u2010COVID period, accounting for up to one\u2010third of positive cases, becoming the most prevalent respiratory virus (excluding SARS\u2010CoV\u20102).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>These findings suggest a notable impact of the COVID\u201019 pandemic and associated NPIs on respiratory virus circulation on Reunion Island since mid\u20102020. They underscore the complex interplay between viral interference, public health interventions, behavioral changes, and youth immunity, emphasizing the need for adaptable strategies in managing respiratory virus outbreaks in the post\u2010COVID\u201019
