A form of maltreatment of a child. Somebody may abuse or neglect a child by inflicting harm, or by failing to act to prevent harm. Children may be abused in a family or in an institutional or community setting by those known to them or, more rarely, by others. Abuse can take place wholly online, or technology may be used to facilitate offline abuse. Children may be abused by an adult or adults, or another child or children.
