Abstract
The International Health Regulations (IHR), the principal legal instrument guiding the international management of public health emergencies, have recently undergone an extensive revision process. The revised regulations, referred to as the IHR (2005), were unanimously approved in May 2005 by all Member States of the World Health Assembly (WHA) and came into effect on 15 June 2007. The IHR (2005) reflect a modernization of the international community’s approach to public health and an acknowledgement of the importance of establishing an effective international strategy to manage emergencies that threaten global health security.
