[Management of the Sars-Cov2 pandemic in France - Benefit-risk balance at the collective versus individual level individual scale in children].

According to the precautionary principle and facing the initial uncertainty of the potential seriousness of Covid-19, France has adopted collective measures understood as acceptable despite the deprivation of liberty and the known risks of long confinement on mental health. Such measures should be applied proportionately and cause the least possible harm. Among these, the closure of schools was decided by declination of those appearing in response plans to viral pandemics where children play a major role in the transmission of the disease (e.g. flu). In an unprecedented way, measures and constraints have been taken against the interests of children and to protect a vulnerable group other than the children themselves. From the perspective of children's health, the relationship between health gains from these measures and negative consequences has been unbalanced. The reduction in instruction time has reduced overall academic performance and has had adverse consequences for the socialization and development of children. Confinement has generated more serious domestic accidents, an increase in intra-family violence and marked collateral effects in terms of the mental health of adolescents. Very early on, the various Covid19-related publications showed that children were not the driving force behind this pandemic - If the initial application of collective measures was legitimate, the adaptation of measures at the individual level was out of step with the already known repercussions followed by those observed on the health of the child.
