Overall, the number of NCH residents ranged from 42 to 1459 with a mean age between 67.6 and 85 years. Attack rates ranged from 6.7% to 47.6% and annual incidence ranged from 0.5% to 14%. Case fatality rates ranged from 7.7% to 23.1%. We found similar annual incidence rates of RSV-positive acute respiratory infection (ARI) of 4582 (95% CI: 3259–6264) and 4785 (95% CI: 2258–10,141) per 100,000 reported in two studies. Annual incidence rate of RSV-positive lower respiratory tract infection was 3040 (95% CI: 1986–4454) cases per 100,000 adults. Annual RSV-ARI hospital admission rates were between 600 (95% CI: 190–10,000) and 1104 (95% CI: 350–1930) per 100,000 person-years.

[<span>1</span>] that describes the prevalence of respiratory infections caused by endemic human coronaviruses (eHCoVs) during the COVID-19 pandemic in Iran, indicating their low prevalence.</p><p>The COVID-19 pandemic has sparked a renewed interest in eHCoVs, which account for an estimated 5%–10% of acute respiratory infections (ARI) in temperate climates [<span>2</span>]. These endemic human coronaviruses are widespread globally and generally result in mild to moderate infections of the upper respiratory tract. However, systematic surveillance data on the epidemiology of endemic coronaviruses NL63, HKU1, OC43, and 229E are currently lacking due to their underappreciated clinical and epidemiological impact. In pre-pandemic years, respiratory virus detections followed a stable seasonal pattern. Many studies, including the one discussed here, showed the low circulation of seasonal respiratory viruses, especially endemic coronaviruses, during the COVID-19 pandemic [<span>1, 2</span>]. This was followed by a marked increase after the first and second lockdowns [<span>3</span>]. Compared to 2019, respiratory virus numbers increased by 23% in 2020, 100% in 2021, and 270% in 2022 [<span>3</span>].</p><p>This reduction in virus circulation is mainly attributed to nonpharmaceutical interventions (NPIs) like travel restrictions, temporary lockdowns, school closures, mask-wearing, and improved hygiene practices. These measures likely played an important role in decreasing coronavirus transmission [<span>2</span>]. However, evaluating the impact of NPIs is complex and influenced by factors such as pathogen characteristics, demographics, and timing and location of NPIs. Competition between SARS-CoV-2 and other viruses may also affect epidemiology [<span>4</span>]. Additionally, prolonged periods of reduced exposure to common pathogens can lead to a temporary decrease in population immunity. With reduced exposure during the pandemic, people's immune systems might not be as prepared to fend off these endemic viruses once they re-emerge [<span>5</span>]. The pandemic disrupted the usual circulation patterns of many viruses, allowing some viruses suppressed during the pandemic to find new opportunities to spread once normal activities resumed.</p><p>After the low circulation of eHCoVs during the COVID-19 pandemic, a seasonal increase in respiratory pathogens is expected. As it is mentioned in the Karami et al. article, surveillance research is essential to monitor eHCoV distribution patterns and identify changes in the epidemiology of these viruses. This is essential for developing strategies to timely control the future outbreaks of eHCoVs throughout the nation [<span>1</span>]. In this direction, we examined all adults with acute respiratory infection symptoms presenting to the Emergency and Respiratory Medicine Departments of the University Hospital of Larissa (UHL), Greece, between Novemb","PeriodicalId":13544,"journal":{"name":"Influenza and Other Respiratory Viruses","volume":null,"pages":null},"PeriodicalIF":4.3,"publicationDate":"2024-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/irv.70001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142008762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
