This distress has been described on adults, but no data have been collected yet for paediatric populations.

Moreover, PTSD in children and adolescents is often associated with comorbid disorders, such Attention Deficit Hyperactivity Disorder, depression, attachment and anxiety disorders, sleep disturbances and behavior problems. The aim of this study is to present the methodology of "CoCo 20" : is to assess the impact of the pandemic of coronavirus disease 2019 (Covid-19) and of seclusion measures on mental health and on the development of psychological disorders in children in the short to medium term
