Last year, COVID-19, a respiratory disease caused by the virus SARS-CoV-2, managed to infect more than 200 million humans, cause almost 5 million deaths, and establish itself as a prevailing matter in all facts of life (Worldometer, Coronavirus cases). While the medical details of COVID-19 have seen extensive research, relatively less attention has been paid to its mental health effects, especially in the context of children and adolescents. Our aim in this report is to discuss and analyze the various results of previous studies in this field and conduct our own analyses to bring forth new conclusions. The creation of this report was overseen by the World Health Organization's EPI-WIN Team.
