The impact of the COVID-19 pandemic on influenza, respiratory syncytial virus, and other seasonal respiratory virus circulation in Canada: A population-based study

Abstract: Background The ongoing coronavirus disease 2019 (COVID-19) pandemic has resulted in implementation of public health measures worldwide to mitigate disease spread, including; travel restrictions, lockdowns, messaging on handwashing, use of face coverings and physical distancing. As the pandemic progresses, exceptional decreases in seasonal respiratory viruses are increasingly reported. We aimed to evaluate the impact of the pandemic on laboratory confirmed detection of seasonal non-SARS-CoV-2 respi… Show more

“…In conclusion, our study showed a significant reduction in overall outpatient antibiotic prescribing during the COVID-19 pandemic in Ontario. The sustained reductions in observed antibiotic prescriptions appear to have been driven by implementation of public health measures that reduced respiratory infection transmission [ 20 , 21 , 45 ]. However, we observed a modest reduction in antibiotic prescriptions/visits with respiratory infection.…”

“…The experience gained with IAPA during the past decade is one of the reasons why CAPA was soon recognized as an important entity in severe COVID-19. Despite being the newer entity, more and larger (prospective) trials have been performed on CAPA than on IAPA, as prospective IAPA research was hampered by the (near complete) worldwide disappearance of severe influenza since the start of the COVID-19 pandemic [114]. Several similarities exist between both entities: they both occur in critically ill patients with severe respiratory distress, are associated with an increased mortality, and as in CAPA, a wide (regional and probably at least partially test strategy-related) variation in IAPA incidence has been described [97,115,116].…”
