Mental health assistance to populations affected by disasters: World Health Organization's role.

In this article, the authors describe the role of the World Health Organization (WHO) in mental health post-disaster recovery. The article covers the mandate and structure of WHO, mental health activities by the WHO Department of Mental Health and Substance Abuse, WHO-supported principles and strategies in mental health post-disaster recovery, and available WHO technical assistance. The paper outlines a public mental health approach to make very basic mental health services broadly available in post-disaster countries. Using examples based on the Asian tsunami experience, suggestions for delivering mental health assistance are made. The response to mental health of disaster victims should be seen in the context of national health priorities.
