A small minority of parents decline to provide their children with certain kinds of medical care because they claim doing so would violate their religious beliefs. The type of care declined may be limited to specific practices such as vaccinations or blood transfusions; in more extreme cases, a parent may reject all forms of modern medicine and focus on spiritual "healing" instead—by, for example, attempting to heal the child through prayer. In the U.S., state laws on this subject vary widely. However, many states do still allow religious exemptions to certain kinds of medical care and do not automatically consider such behavior to be child abuse or neglect—even, in some cases, if the child dies due to lack of care. Child deaths as a result of religiously-motivated medical neglect are thought to be rare; however, their true extent is unknown, and many experts and medical providers argue that there should be no religious exemptions in matters of children's health.
