The roles of the health sector and health workers before, during and after violent conflict.

Starting with a view of war as a significant population health problem, this article explores the roles of health workers in relation to violent conflict.

We propose here two statements, one dealing with the broad issue of public health ethics and international relations, and one dealing specifically with public health ethics and water purification.
