Violence against children takes many sinister forms. In homes, schools, communities and online around the world, it manifests itself in debilitating physical and emotional abuse. In humanitarian emergencies – especially those driven by relentless armed conflicts – violence can result in death, serious injury and lasting trauma. An insidious sort of violence also affects children when humanitarian emergencies deprive them of health, nutrition, water and sanitation, education and other basic needs. Humanitarian Action for Children 2019 underscores the urgency of protecting children in crisis from all such threats to their lives, well-being and dignity.
