Reopening schools in the context of increasing COVID-19 community transmission: The French experience.

ABSTRACT:

Background and objectives

The role of schools in the spread of SARS-CoV-2 infections in the community is still controversial. The objective of our study was to describe the epidemiology of SARS-CoV-2 infections in different pediatric age groups during the first 2 months of the fall back-to-school period, in the context of increasing viral transmission in France.

Methods

Weekly epidemiological data provided by Santé Publique France and the Ministry of National Education were analyzed according to the age groups defined by the different school levels. Weeks (W) 34-42 were considered for analysis.

Results

The PCR positivity rate and incidence rate increased in all age groups during the study period, in an age-dependent manner. At W42, with adults being considered as reference, the risk ratio for a positive PCR test was 0.46 [95% CI: 0.44-0.49] and 0.69 [0.68-0.70] for children aged 0-5 years and 6-17 years, respectively. Similarly, the incidence rate ratio was 0.09 [0.08-0.09], 0.31 [0.30-0.32], 0.64 [0.63-0.66], and 1.07 [1.05-1.10] for children aged 0-5 years, 6-10 years, 11-14 years, and 15-17 years, respectively. Children and adolescents accounted for 1.9% of the newly hospitalized patients between W34 and W42, and for 1.3% of new intensive care admissions. No death was observed. Among infected children and adolescents, the percentage of asymptomatic individuals was 57% at W34 and 48% at W42. The number of schools closed remained low, less than 1% throughout the study period. The number of confirmed cases among school staff was consistent with the data measured in the general population.

Conclusion

In the context of increasing viral transmission in the population, the spread among children and adolescents remained lower than that observed among adults, despite keeping schools open. However, the impact was age-dependent, with data in high schools close to those observed in adults.

Project description:BackgroundSchools and preschools have largely remained open in Norway throughout the pandemic, with flexible mitigation measures in place. This contrasts with many other high-income countries that closed schools for long periods of time. Here we describe cases and outbreaks of COVID-19 in schools and preschools during the academic year 2020/2021, to evaluate the strategy of keeping these open with infection prevention control measures in place.MethodsIn this descriptive study, the Norwegian Institute of Public Health initiated systematic surveillance for COVID-19 cases and outbreaks in schools and preschools in October 2020. Data was compiled from the national outbreak alert system VESUV, municipality websites, and media scanning combined with the national emergency preparedness register Beredt C-19. An outbreak was defined as ≥ 2 cases among pupils or staff within 14 days at the same educational setting. Settings were categorized as preschool (1-5-years), primary school (6-12-years), lower secondary school (13-15-years) and upper secondary school (16-18- years). We reported the incidence rate among preschool and school-aged pupils and gave a descriptive overview of outbreaks and included cases per educational setting.ResultsDuring the whole academic year, a total of 1203 outbreaks in preschools and school settings were identified, out of a total of 8311 preschools and schools nationwide. The incidence of COVID-19 in preschool- and school-aged children and the rates of outbreaks in these settings largely followed the community trend. Most of the outbreaks occurred in primary schools (40%) and preschools (25%). Outbreaks across all settings were mostly small (median 3 cases, range 2 to 72), however, 40 outbreaks (3% of total) included 20 or more cases. The larger outbreaks were predominantly seen in primary schools (43%).ConclusionsWe observed few large outbreaks in open schools and preschools in Norway during the academic year of 2020/2021, also when the Alpha variant was predominant. This illustrates that it is possible to keep schools and preschools open even during periods of high community transmission of COVID-19. Adherence to targeted IPC measures adaptable to the local situation has been essential to keep educational settings open, and thus reduce the total burden on children and adolescents.

Project description:BackgroundSchool closures in response to the COVID-19 impacted children's education, protection, and wellbeing. After understanding these impacts and that children were not super spreaders, countries including Ethiopia decided to reopen schools with specified preconditions. But when deciding to reopen schools, the benefits and risks across education, public health and socio-economic factors have to be evaluated. However, there was information gap on status of schools as per preconditions. Hence, this study was designed to investigate status of schools in Southern Ethiopia.MethodsSchool based cross-sectional study was conducted in October 2020 in Southern Ethiopia. Sample of 430 schools were included. National school reopening guideline was used to develop checklist for assessment. Data was collected by public health experts at regional emergency operation center. Descriptive analysis was performed to summarize data.ResultsA total of 430 schools were included. More than two thirds, 298 (69.3%), of schools were from rural areas while 132 (30.7%) were from urban settings. The general infection prevention and water, sanitation and hygiene (IPC-WASH) status of schools were poor and COVID-19 specific preparations were inadequate to meet national preconditions to reopen schools during the pandemic. Total score from 24 items observed ranged from 3 to 22 points with mean score of 11.75 (SD±4.02). No school scored 100% and only 41 (9.5%) scored above 75% while 216 (50.2%%) scored below half point that is 12 items.ConclusionBoth the basic and COVID-19 specific IPC-WASH status of schools were inadequate to implement national school reopening preconditions and general standards. Some of strategies planned to accommodate teaching process and preconditions maximized inequalities in education. Although COVID-19 impact lessened due to vaccination and other factors, it is rational to consider fulfilling water and basic sanitation facilities to schools to prevent communicable diseases of public health importance.
