While disease outbreaks and other acute public health risks are often unpredictable and require a range of responses, the International Health Regulations (2005) (IHR) provide an overarching legal framework that defines countries’ rights and obligations in handling public health events and emergencies that have the potential to cross borders.
The IHR are an instrument of international law that is legally-binding on 196 countries, including the 194 WHO Member States. The IHR grew out of the response to deadly epidemics that once overran Europe. They create rights and obligations for countries, including the requirement to report public health events. The Regulations also outline the criteria to determine whether or not a particular event constitutes a “public health emergency of international concern”.
