The pandemic coronavirus 2019 (COVID-19) has caused considerable changes in everyday living and normal activities, as well as severe health, economic, financial, and social effects. Lockdowns and physical/social separation measures were deployed in numerous nations throughout the world beginning in March 2020. COVID-19 has claimed the lives of hundreds of thousands of people worldwide. This tremendous loss of life, along with the rapid changes in daily living brought on by the COVID-19 pandemic, may have a negative impact on child and adolescent mental health. There is a paucity of scientific research on the consequences of the COVID-19 pandemic on the mental health of children and adolescents.
