The Public Health Emergencies of International Concern (PHEIC) procedures: Some serious public health events that endanger international public health may be determined under the Regulations to be public health emergencies of international concern (PHEIC). The term Public Health Emergency of International Concern is defined in the IHR (2005) as “an extraordinary event which is determined, as provided in these Regulations: to constitute a public health risk to other States through the international spread of disease; and to potentially require a coordinated international response”. This definition implies a situation that: is serious, unusual or unexpected; carries implications for public health beyond the affected State’s national border; and may require immediate international action.
