Child abuse is the physical or psychological/emotional mistreatment of children. In the United States, the Centers for Disease Control and Prevention define child maltreatment as any act or series of acts of commission or omission by a parent or other caregiver that results in harm, potential for harm, or threat of harm to a child. Most child abuse occurs in a child's home, with a smaller amount occurring in the organizations, schools or communities the child interacts with. There are four major categories of child abuse: neglect, physical abuse, psychological/emotional abuse, and sexual abuse.Different jurisdictions have developed their own definitions of what constitutes child abuse for the purposes of removing a child from his/her family and/or prosecuting a criminal charge. The mental health journal[clarification needed] states that child abuse is defined as "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, an act or failure to act which presents an imminent risk of serious harm".
