The World Health Organization (WHO) defines "child abuse" and "child maltreatment" as "all forms of physical and/or emotional ill-treatment, sexual abuse, neglect or negligent treatment or commercial or other exploitation, resulting in actual or potential harm to the child's health, survival, development or dignity in the context of a relationship of responsibility, trust or power." The WHO also says, "Violence against children includes all forms of violence against people under 18 years old, whether perpetrated by parents or other caregivers, peers, romantic partners, or strangers." In the United States, the Centers for Disease Control and Prevention (CDC) uses the term "child maltreatment" to refer to both acts of commission (abuse), which include "words or overt actions that cause harm, potential harm, or threat of harm to a child", and acts of omission (neglect), meaning "the failure to provide for a child's basic physical, emotional, or educational needs or to protect a child from harm or potential harm". The United States federal Child Abuse Prevention and Treatment Act defines "child abuse and neglect" as, at minimum, "any recent act or failure to act on the part of a parent or caretaker which results in death, serious physical or emotional harm, sexual abuse or exploitation" or "an act or failure to act which presents an imminent risk of serious harm".
