The COVID-19 crisis highlights the fact that mental health affects the entire population, not just a minority. In addition to acutely exacerbating mental health issues, the pandemic has exposed vulnerabilities and inequalities within the population. It raises long-term questions regarding children’s psychological and overall development, young people’s entry into the workforce, and their path to independence. It has brought to light a pre-existing crisis in psychiatry, particularly in child psychiatry. It represents a turning point in how mental health is approached: the focus of mental health policies is no longer solely on the organization of psychiatric care; It has broadened its scope to encompass the mental health of the general population, as well as prevention and health promotion efforts: this includes the accelerated rollout of suicide prevention programs and helplines, but also involves mobilizing—in addition to healthcare professionals—all stakeholders capable of contributing to mental health, including those in the social sector, housing, and education.
