The COVID-19 crisis highlights the fact that mental health affects the entire population, not just a minority. In addition to sharply exacerbating mental health issues, the pandemic has laid bare vulnerabilities and inequalities within the population. It raises long-term questions about children’s psychological and overall development, as well as young people’s entry into the workforce and their path to independence. It brings to light a pre-existing crisis in psychiatry, particularly in child psychiatry. It represents a turning point in how mental health is addressed: the focus of mental health policies is no longer limited to the organization of psychiatric care; it is expanding more broadly to address the mental health of the general population, as well as prevention and health promotion efforts: through the accelerated rollout of suicide prevention programs and helplines, as well as by mobilizing—in addition to healthcare professionals—all stakeholders capable of contributing to mental health, including those in the social services, housing, and education sectors.
