“…Past studies have shown that frequent, e↵ective handwashing can result in a comparable moderate reduction in infections [23,24,25]. A meta-analysis of the e↵ects of NPIs in reducing influenza transmission demonstrated that hand hygiene was significant in reducing influenza transmission, with an odds ratio of 0.62 [26].…”

The 2019-2020 influenza sentinel surveillance data exhibits unexpected trends. Typical influenza seasons have a small herald wave, followed by a decrease due to school closure during holidays, and then a main post-holiday peak that is significantly larger than the pre-holiday wave. During the 2019-2020 influenza season, influenza-like illness data in the United States appears to have a markedly lower main epidemic peak compared to what would be expected based on the pre-holiday peak. We hypothesize that the 2019-2020 influenza season does have a lower than expected burden and that this deflation is due to a behavioral or ecological interaction with COVID-19. We apply an intervention analysis to assess if this influenza season deviates from expectations, then we compare multiple hypothesized drivers of the decrease in influenza in a spatiotemporal regression model. Lastly, we develop a mechanistic metapopulation model, incorporating transmission reduction that scales with COVID-19 risk perception. We find that the 2019-2020 ILI season is smaller and decreases earlier than expected based on prior influenza seasons, and that the increase in COVID-19 risk perception is associated with this decrease. Additionally, we find that a 5% average reduction in transmission is su cient to reproduce the observed flu dynamics. We propose that precautionary behaviors driven by COVID-19 risk perception or increased isolation driven by undetected COVID-19 spread dampened the influenza season. We suggest that when surveillance for a novel pathogen is limited, surveillance streams of co-circulating infections may provide a signal.

“…Yet, in terms of the participants' attitudes toward wearing masks in pre-operative evaluations, only 11.8% stated that they wore masks continuously. Although studies have stated that healthcare providers prefer to not use personal protective equipment because their use increases emergency patient response time or because such equipment is impractical, healthcare providers should perform necessary medical interventions while protecting their own health as well [14][15][16]. In our study, a large proportion of the participants (43.9%) stated that they started wearing masks after the pandemic because of fear of disease transmission.…”

A total of 346 anesthesiology specialists and residents participated in the study. Although the majority of the participants exhibited the correct attitudes toward airway management, research assistants with little professional experience were observed to be undecided or had the tendency to make incorrect decisions. Conclusions: The COVID-19 pandemic is spreading rapidly worldwide. The incidence of COVID-19 cases is increasing daily, and this disease can cause patient death. Anesthesiology specialists and residents who perform emergency operations on these patients in settings other than intensive care units should follow simple and easy-to-understand algorithms to ensure safety. The provision of theoretical and practical training to healthcare providers before they meet patients will help ensure patient-healthcare provider safety and prevent panic, which can cause distress among healthcare providers.
