 WHO states that "Notification is now based on the identification within a State Party’s territory of an "event that may constitute a public health emergency of international concern".This non-disease specific definition of notifiable events expands the scope of the IHR (2005) to include any novel or evolving risk to international public health, taking into account the context in which the event occurs.Such notifiable events can extend beyond communicable diseases and arise from any origin or source.
