This handbook is a comprehensive and timely contribution to building the field of Conflict and Health, which has yet to be recognized as a key component of public health by professional associations, state health agencies, donors, health research agencies, university accreditors or publishers. It covers fundamentals such as food security, the decolonization of aid and international governance structures, but also topics less covered such as violence as contagion, siege warfare, street medics, the involvement of combatants in humanitarian operations, intergenerational consequences of violence, bereavement, and military involvement in academia, among many other critical issues.
