During most of its long history, the public function in mental health primarily was on care of the chronically ill mental patient, as illustrated by the large hospitals for the mentally ill. This activity in personal health services contrasted with the usual public health focus on prevention of disease and protection of the health of the public. Differing perspectives and operating modes were often reflected in organizational separation of mental health from public health at the state level.
