In developing contexts such as India, children in adversity form a high-risk group, one that cannot be subsumed under the general category of children, who are generally considered as a vulnerable group in disaster and crisis situations. Child mental health issues in contexts of protection risks and childhood adversity tend to be over-looked in such crises. This article focuses on examining the impact of the COVID-19 pandemic and its socio-economic consequences on children in adversity, describing the increased child protection and psychosocial risks they are placed at, during and in the immediate aftermath of the COVID-19 crisis and its lockdown situation. It specifically links the lockdown and the ensuing economic issues to sexuality and abuse-related risks, as occur in contexts of child labour, child sex work and trafficking, child marriage and child sexual abuse, and that result in immediate and long-term mental health problems in children. It proposes a disaster risk reduction lens to offer recommendations to address the emerging child protection, psychosocial and mental health concerns.
