Child sexual abuse refers to any sexual act perpetrated against a child. It can include contact acts like kissing, fondling, oral sex, as well as non-contact acts like sexual remarks, online solicitation, voyeurism, and showing pornography. Child sexual abuse has been linked to long-term negative mental health impacts in victims like depression, dissociation, post-traumatic stress disorder, anxiety, and substance abuse. Preventing child sexual abuse requires a community effort including mandatory reporting of suspected cases, educating children and teachers, and creating a supportive environment where victims feel comfortable coming forward.
