Background: The coronavirus disease 2019 (COVID-19) pandemic is having an intense effect on all aspects of society, including mental health and physical health. A major adverse consequence of the COVID-19 pandemic is likely to be increased social isolation and loneliness which are strongly associated with anxiety and depression. Tracking loneliness and intervening early are important priorities. Crucially, reducing sustained feelings of loneliness, and promoting belongingness are candidate mechanisms to protect against self-harm and emotional problems. Social and physical distancing has abruptly interrupted many social opportunities important to physical and psychological health. Method: In this study, 2140 children of different categories (gender, age, education, region, and location) have participated. The questionnaires depend upon the argument tendency, depressive order, adverse mental problem symptoms, behavioural health symptoms, and anxiety disorder. Results: It is observed that children face anxiety, depressive disorder, argument tendency and show adverse mental problem symptoms, behavioural health symptoms, and COVID-19 related trauma and stressor-related disorder. Conclusion: The present paper also deals with how the parents can help the children coping with stress during this COVID-19.
