RESUMEN
This chapter describes and analyzes how different countries dealt with children and youth with mental health issues before and during the COVID-19 pandemic beginning in March 2020. The pandemic and measures worldwide to control the spread of the virus COVID-19, such as lockdowns, closures of schools and preschools, social distancing rules, restrictions of movement, contact limits, and quarantine, changed the daily life of millions of people, especially children and youth. The countries include: Germany, Greece, Portugal, Tanzania/Vietnam, and the Netherlands. The chapter also analyzes how fear of infection and death, high uncertainty, and the containment measures that were implemented on affected children and youth with mental health issues. Students with disabilities and students from disadvantaged backgrounds were particularly affected by school closures. Mental health systems in the various countries coped in different ways, also depending on how they operated before the pandemic. Developing prevention programs, building resiliency, peer support, online support measures, and raising awareness of mental health all seem to be useful strategies to address mental health problems in children and youth.
