IntroductionSince the SARS-CoV-2 became of concern in January 2020, many preventive measures have been adopted in educational settings to ensure the control of COVID-19 pandemic among children and staff in schools. This study aims to set up a school sentinel surveillance network with the purpose of monitoring SARS-CoV-2 infection, seroprevalence as well as to analyse the impact of preventive interventions of SARS-CoV-2 in school settings. Additionally, we will assess diverse screening strategies in a cohort of students and school staff to monitor the screening acceptance and its potential impact. Altogether, we hope this study will enable the design of more effective strategies for the prevention of COVID-19 spread.Methods and analysisThe sentinel schools’ study is a cross-sectional, school-based project including 26 participating sentinel schools in Catalonia (Spain). Children, adolescents and staff at the schools will be invited to participate. This project will be carried out from January 2021 to June 2022 as follows: (1) twice yearly serological testing and molecular SARS-CoV-2 detection and questionnaires covering SARS-CoV-2 symptoms, tests, health, knowledge, attitudes and behaviours; (2) an environmental evaluation carried out in different classrooms; (3) SARS-CoV-2 transmission dynamics and the impact of different variants among confirmed cases and classmates; (4) a participatory process by which the participants are invited to act as coinvestigators to evaluate prevention strategies and provide recommendations to improve COVID-19 prevention in schools. Descriptive analysis will be performed for the main variables collected. The incidence and seroprevalence will be calculated and the association with sociodemographic factors and school characteristics will be determined using multivariate logistic regression.Ethics and disseminationEthical approval was obtained from the IDIAPJGol and the Hospital Universitari Vall d’Hebron ethics committees. A report will be generated quarterly. Findings will be disseminated at national and international conferences and published in peer-reviewed journals.
Objectives: The European Centre for Disease Control (ECDC) COVID-19 guidelines for non-pharmaceutical interventions (NPI) identify safety, hygiene and physical distancing measures to control SARS-Cov-2 transmission in schools. Because their implementation requires complicated changes, the guidelines also include “accompanying measures” of risk communication, health literacy and community engagement. Although these are considered crucial, their implementation is complex. This study aimed to co-define a community partnership that a) identifies systemic barriers and b) designs recommendations on how to implement the NPI to improve SARS-Cov-2 prevention in schools.Methods: We designed and piloted a System-Oriented Dialogue Model with the participation of 44 teachers and 868 students and their parents from six Spanish schools during 2021. The results were analysed using thematic analysis.Results: Participants identified 406 items addressing issues related to system characteristics, which is indicative of the complexity of the challenge. Using a thematic analysis, we defined 14 recommendations covering five categories.Conclusion: These findings could help in developing guidelines for initiating community engagement partnerships in schools to provide more integrated prevention interventions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
