COVID-19 and re-opening of schools: Opinions with scientific evidence

Abstract

Due to the COVID-19 pandemic, more than 90% of students worldwide were affected by education loss. Moreover, for school-age children and adolescents, there may be worsening of nutrition, increasing mental health disorders, lack of physical activity, and related deleterious consequences raise concerns about negative habits, child violence, and abuse. Face-to-face education in schools provides positive educational opportunities that cannot be achieved with online education. In studies from various countries, children have milder disease, constituting as little as 1-8% of all laboratory-confirmed COVID-19 cases, with less transmission capacity to household contacts than adults (0.5-7% vs. 10-20%). Symptomatic or asymptomatic children can infect other people less than adults. Also, the transmission of illness between students at school is less than expected, and the transmission of COVID-19 to students is usually acquired from sick adults rather than sick students. Therefore, with suitable measures, infection risk is less than expected and seems not to be higher than in other public places. COVID-19 measures in schools can be summarized as follows: avoiding crowded/close contact environments as much as possible, respecting the protective (social) distance, wearing appropriate masks, hand hygiene, and some essential protective measurements of classrooms and environment. Measurements should be participatory (students, teachers, education staff, parents, administration), applicable, sustainable, and flexible according to the conditions.
