“…On the contrary, evidence from Rhode Island in the US, noted a very small number of cases after schools reopened during June-July 2020, which the authors attribute to the strict non-pharmaceutical interventions implemented including the use of face masks, physical distancing, screening for symptoms and classroom disinfection (22). A similar experience has been highlighted in Hong Kong, where multiple potential introductions of COVID-19 did not lead to secondary transmission, amidst a setting with numerous precautionary in-school measures, such as widespread facemask use, daily temperature checks, and staggered entries and exits (36).…”

Decisions on school closures and on safe schooling during the COVID-19 pandemic should be evidence-based. We conducted a systematic literature review to assess child-to-child and child-to-adult SARS-CoV-2 transmission and to characterise the potential role of school closures on community transmission. 1337 peer-reviewed articles published through August 31, 2020 were screened; 22 were included in this review. The literature appraised provides sufficient evidence that children can both be infected by and transmit SARS-CoV-2 in community, household and school settings. Transmission by children was most frequently documented in household settings, while examples of children as index cases in school settings were rare. Included studies suggested that school closures may help to reduce SARS- CoV-2 transmission, but the societal, economic, and educational impacts of prolonged school closures must be considered. In-school mitigation measures, alongside continuous surveillance and assessment of emerging evidence, will promote the protection and educational attainment of students and support the educational workforce.

“…Such data has only been used in (family) case cluster studies (e.g. Chan et al 2020 ; Danis et al 2020 ; Fong et al 2020 ). In the context of our study, of particular interest would have been being able to distinguish between the proportion of infections that took place outside the home (more likely among children and people employed) and those within the household (more probable among older people and those living in multigenerational or overcrowded households).…”

By late January 2020, the 2019 novel coronavirus (SARS-CoV-2) had reached Europe and most European countries had registered cases by March 1. However, the spread of the virus has been uneven in both prevalence and speed of propagation. We analyse the association of social, economic, and demographic factors in the initial spread of the coronavirus disease COVID-19 across 23 European countries between March 1 and April 30, 2020. Diagnosed COVID-19 cases from Johns Hopkins University and data from the European Social Survey and other sources were used to estimate bivariate associations between cumulative reported case numbers at ten-day intervals and nine social, demographic, and economic variables. To avoid overfitting, we first reduce these variables to three factors by factor analysis before conducting a multiple regression analysis. We also perform a sensitivity analysis using rates and new cases between two time periods. Results showed that social and economic factors are strongly and positively associated with COVID-19 throughout the studied period, while the association with population density and cultural factors was initially low, but by April, was higher than the earlier mentioned factors. For future influenza-like pandemics, implementing strict movement restrictions from early on will be crucial to curb the spread of such diseases in economically, socially, and culturally vibrant and densely populated countries.

“…In Hong Kong, 20 confirmed cases of COVID-19 in schoolchildren aged 5to17 were investigated to gain more knowledge about the spread of infection in schools. Through broad school testing and medical monitoring of cases and their close contacts, the study showed that no more cases could be linked to the 20 cases, indicating that the risk of further infectivity in schools is limited (54).…”
