Early school closures can reduce the first-wave of the COVID-19 pandemic development.

ABSTRACT: Aim:The COVID-19 pandemic presents serious threats to global public health and the world economy. Therefore, the rapid escalation of the number of cases has led to national government and global interventions. This study aimed to assess the effect of school closures on the COVID-19 pandemic and epidemic trajectories in selected countries. Subject and methods:Information on the number of cases and population in each country were taken from official government reports. Dates of educational institutions closure were taken from the UNESCO database. Statistical analyses were performed using Statistica. We summarized the data graphically and descriptively. Results:Most of the European countries closed schools in the period of 11-20 of March 2020. However, there was a big difference in the phase of the epidemic on the day of closure. The data indicate that there was a strong correlation between the day of educational facilities closure and the incidence rate in the following days (16th, 30th, and 60th days since the 100th confirmed case in each country). Early closure of schools in analyzed countries is statistically significantly correlated with lower incidence rates further on during the different phases of the epidemic. Thereby closure of schools with delay is statistically significantly correlated with a higher incidence rate in the following days. Conclusion:The available data suggest that school closures can potentially reduce transmission during the pandemic, although more research is needed on the effectiveness of these practices.

Project description:ObjectiveThe objective of this scoping review is to provide an overview of existing studies and evidence on the impact of school closures and reopenings during the pandemic.IntroductionThe COVID-19 pandemic has necessitated widespread school closures, and reopening schools safely has a pivotal role in the well-being of children and teachers, SARS-CoV-2 transmission control and optimal societal functioning. Widespread school closures in response to the COVID-19 pandemic have caused adverse effects on the education, physical health and mental well-being of children. An understanding of the impact of school closures and reopenings as well as factors influencing school safety is critical to bringing schools' operational status back to normal. Despite the implication of individual concerns and knowledge on disease prevention practices, there is a paucity of research on individual knowledge, needs and behaviours in the context of school reopenings. In the proposed study, we will conduct a scoping review to identify and provide inventory of the current research and evidence on the impact of COVID-19 on K-12 schools (primary and secondary schools) and vice versa.Methods and analysisEligible studies/literature include members of K-12 (primary and secondary) schools (students, parents, staff, faculty, COVID-19 coordinator, school nurses) in countries affected by the COVID-19 pandemic. We will exclude university or college students. There will be no exclusion based on methods, timing or school operational status.All concepts regarding school closures and reopenings will be considered, and all types of research will be considered.This scoping review will follow the Joanna Briggs Institute methodology for scoping reviews. Sources of evidence published from 2020 to 31 October 2021 will be included. The search will include PubMed, preprints in EuropePMC, ERIC, Scopus, Web of Science Core Collection, PsycINFO, Embase, CINAHL and VHL. We will cover grey literature in Harvard Think Tank Database, COVID-19 Evidence Hub like COVID-END and Google Scholar. The abstract and title screening, full-text screening and data extraction will be done by two independent reviewers.Disagreements will be resolved by an independent third reviewer. Data extract will be done on Qualtrics form to ensure accurate extraction. Citation chaining will be performed on key articles identified. A critical appraisal will be performed.The scoping review will take place from 1 August 2021 to 15 November 2021. We will perform a final round of updated search and citation chaining.Ethics and disseminationThe review will be based on published works and grey literature, thus it is exempt from formal ethical approval. This protocol cannot be registered in the Prospective Register of Systematic Reviews because this registry is not for scoping reviews. We will register it in OSF Registration. The paper will appear in a peer-reviewed, open-access journal to ensure a broad dissemination.

Project description:BackgroundOn January 30th 2020, the World Health Organization (WHO) declared a international health emergency due to the unprecedented phenomenon of COVID-19. After this declaration countries swiftly implemented a variety of health policies. In this work we examine how rapid countries responded to this pandemic using two events: the day in which the first case of COVID-19 was reported, and first day in which countries used school closure as one of the measures to avoid outbreaks. We also assessed how countries' health systems, globalization, economic development, political systems, and economic integration to China, Republic of Korea and Italy increased the speed of adoption.MethodsWe compiled information from multiple sources, from December 31st 2019 to June 1st 2020, to trace when 172 countries reported their first COVID-19 case and implemented school closure to contain outbreaks. We applied cross-national Weibull survival analysis to evaluate the global speed of detection of first COVID-19 reported cases and school closure.ResultsTen days after WHO declared COVID-19 to be an international emergency, relative to seven days from this declaration, countries were 28 (95% CI: 12-77) times more likely to report first COVID-19 cases and 42 (95% CI: 22-90) times more likely to close schools. One standard deviation increase in the epidemic security index rises the rate of report first cases by 37% (Hazard Ratio (HR) 1.37 (95% CI: 1.09-1.72) and delays the adoption for school closures by 36% (HR 0.64 (95% CI:0.50-0.82). One standard deviation increase in the globalization index augments the adoption for school closures by 74% (HR 1.74 (95% CI:1.34-2.24).ConclusionAfter the WHO declared a global emergency, countries were unprecedently acting very rapidly. While countries more globally integrated were swifter in closing schools, countries with better designed health systems to tackle epidemics were slower in adopting it. More studies are needed to assess how the speed of school closures and other policies will affect the development of the pandemic.

Project description:ImportanceAlthough negative associations of COVID-19 pandemic high school closures with adolescents' health have been demonstrated repeatedly, some research has reported a beneficial association of these closures with adolescents' sleep. The present study was, to our knowledge, the first to combine both perspectives.ObjectiveTo investigate associations between adolescents' sleep and health-related characteristics during COVID-19 pandemic school closures in Switzerland.Design, setting, and participantsThis survey study used cross-sectional online surveys circulated among the students of 21 public high schools in Zurich, Switzerland. The control sample completed the survey under regular, prepandemic conditions (May to July 2017) and the lockdown sample during school closures (May to June 2020). Survey respondents were included in the study if they provided their sex, age, and school.ExposuresHigh school closures during the first COVID-19 pandemic wave in Switzerland (March 13 to June 6, 2020).Main outcomes and measuresSleep-wake patterns, health-related quality of life (HRQoL, assessed by the KIDSCREEN-10 questionnaire), substance use (caffeine, alcohol, and nicotine), and depressive symptoms (lockdown sample only; assessed using the withdrawn/depressed scale from the Youth Self Report). Multilevel regression models were used to assess sample differences and associations of health-related characteristics with sleep duration and depressive symptoms.ResultsThe total sample consisted of 8972 students, including 5308 (59.2%) in the control sample (3454 [65.1%] female) and 3664 (40.8%) in the lockdown sample (2429 [66.3%] female); the median age in both samples was 16 years (IQR, 15-17 years). During school closures, the sleep period on scheduled days was 75 minutes longer (semipartial R2 statistic [R2β*], 0.238; 95% CI, 0.222-0.254; P < .001) and the students had better HRQoL (R2β*, 0.007; 95% CI, 0.004-0.012; P < .001) and less consumption of caffeine (R2β*, 0.010; 95% CI, 0.006-0.015; P < .001) and alcohol (R2β*, 0.014; 95% CI, 0.008-0.022; P < .001). Longer sleep duration was associated with better HRQoL (R2β*, 0.027; 95% CI, 0.020-0.034; P < .001) and less caffeine consumption (R2β*, 0.013; 95% CI, 0.009-0.019; P < .001). In the lockdown sample, an inverse association was found between depressive symptoms and HRQoL (R2β*, 0.285; 95% CI, 0.260-.0311; P < .001) and a positive association was found with caffeine consumption (R2β*, 0.003; 95% CI, 0.000-0.008; P = .01).Conclusions and relevanceIn this survey study, 2 opposing associations between school closures and adolescents' health were identified: a negative association with psychological distress and a beneficial association with increased sleep duration. These findings should be considered when evaluating and implementing school closures. Furthermore, the findings provide support for delaying school start times for adolescents.
