The effects of school closures on SARS-CoV-2 among parents and teachers.

ABSTRACT: To reduce the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), most countries closed schools, despite uncertainty if school closures are an effective containment measure. At the onset of the pandemic, Swedish upper-secondary schools moved to online instruction, while lower-secondary schools remained open. This allows for a comparison of parents and teachers differently exposed to open and closed schools, but otherwise facing similar conditions. Leveraging rich Swedish register data, we connect all students and teachers in Sweden to their families and study the impact of moving to online instruction on the incidence of SARS-CoV-2 and COVID-19. We find that, among parents, exposure to open rather than closed schools resulted in a small increase in PCR-confirmed infections (odds ratio [OR] 1.17; 95% CI [CI95] 1.03 to 1.32). Among lower-secondary teachers, the infection rate doubled relative to upper-secondary teachers (OR 2.01; CI95 1.52 to 2.67). This spilled over to the partners of lower-secondary teachers, who had a higher infection rate than their upper-secondary counterparts (OR 1.29; CI95 1.00 to 1.67). When analyzing COVID-19 diagnoses from healthcare visits and the incidence of severe health outcomes, results are similar for teachers, but weaker for parents and teachers' partners. The results for parents indicate that keeping lower-secondary schools open had minor consequences for the overall transmission of SARS-CoV-2 in society. The results for teachers suggest that measures to protect teachers could be considered.

Project description:ImportanceResurgent COVID-19 cases have resulted in the reinstitution of nonpharmaceutical interventions, including school closures, which can have adverse effects on families. Understanding the associations of school closures with the number of incident and cumulative COVID-19 cases is critical for decision-making.ObjectiveTo estimate the association of schools being open or closed with the number of COVID-19 cases compared with community-based nonpharmaceutical interventions.Design, setting, and participantsThis decision analytical modelling study developed an agent-based transmission model using a synthetic population of 1 000 000 individuals based on the characteristics of the population of Ontario, Canada. Members of the synthetic population were clustered into households, neighborhoods, or rural districts, cities or rural regions, day care facilities, classrooms (ie, primary, elementary, or high school), colleges or universities, and workplaces. Data were analyzed between May 5, 2020, and October 20, 2020.ExposuresSchool reopening on September 15, 2020, vs schools remaining closed under different scenarios for nonpharmaceutical interventions.Main outcomes and measuresIncident and cumulative COVID-19 cases between September 1, 2020, and October 31, 2020.ResultsAmong 1 000 000 simulated individuals, the percentage of infections among students and teachers acquired within schools was less than 5% across modeled scenarios. Incident COVID-19 case numbers on October 31, 2020, were 4414 (95% credible interval [CrI], 3491-5382) cases in the scenario with schools remaining closed and 4740 (95% CrI, 3863-5691) cases in the scenario for schools reopening, with no other community-based nonpharmaceutical intervention. In scenarios with community-based nonpharmaceutical interventions implemented, the incident case numbers on October 31 were 714 (95% CrI, 568-908) cases for schools remaining closed and 780 (95% CrI, 580-993) cases for schools reopening. When scenarios applied the case numbers observed in early October in Ontario, the cumulative case numbers were 777 (95% CrI, 621-993) cases for schools remaining closed and 803 (95% CrI, 617-990) cases for schools reopening. In scenarios with implementation of community-based interventions vs no community-based interventions, there was a mean difference of 39 355 cumulative COVID-19 cases by October 31, 2020, while keeping schools closed vs reopening them yielded a mean difference of 2040 cases.Conclusions and relevanceThis decision analytical modeling study of a synthetic population of individuals in Ontario, Canada, found that most COVID-19 cases in schools were due to acquisition in the community rather than transmission within schools and that the changes in COVID-19 case numbers associated with school reopenings were relatively small compared with the changes associated with community-based nonpharmaceutical interventions.

Project description:Tanzania has experienced several waves of COVID-19 since it was first detected in the country. During the first wave, Tanzania took several measures to prevent wider virus transmission with school closures being one of them. All areas and institutions were targeted, including the refugee camps in Kigoma region. Despite the abundant evidence generated in relation to the effects of the pandemic and associated school closures globally, there has been a paucity of literature exploring the experiences of teachers and students in humanitarian settings. We conducted a qualitative study to explore COVID-19 related school closures in Nyarugusu refugee camp. We aimed to describe teachers' and students' experiences and perceived consequences of school closures. In-depth interviews with teachers and students were conducted in September 2020 in Burundian and Congolese schools in the context of a cluster randomised trial of EmpaTeach, a school-based violence prevention intervention. A total of 44 individuals (29 teachers and 15 students) were interviewed. A phenomenological theoretical framework was used to guide the content analysis. Findings indicated that the COVID-19 pandemic was generally seen as frightening by refugees. Study participants understood the importance of school closures to prevent transmission of the virus, but various negative consequences were reported by both teachers and students. These included perceived mental health difficulties such as stress, depression and anxiety associated with the worry of infection, idleness, and disruption of education. Participants also perceived an increase in occurrences of early marriages and unplanned pregnancies, which they thought contributed to increased school dropout. Participants identified the main causes of such outcomes as a lack of parental supervision, children's lack of restraint and poor character, and a lack of alternative teaching practices (such as online or remote learning) to keep the students busy while at home. Children were held accountable for their faults with little support from the adults. Our findings suggest that there is an urgent need to strengthen child protection programming to support children and their communities during emergencies and provides protective environments such as school and education. There is a critical need to develop preparedness plans for future pandemics to support child safety, academic development and wellbeing.
