International Health Regulations: a major paradigm shift from 1969 to 2005.

The International Health Regulations (IHR 1969), replaced by IHR 2005 had been adopted by the World Health Assembly on 23 May 2005 and came into force on 15 June 2007. IHR 2005 are a legally binding agreement among World Health Organisation (WHO) member states and other states that have agreed to be bound by them. New revision was necessitated by concerns about increasing global health threats and the need to respond with more effective surveillance and control practices. The limitations of IHR 1969, which led to their revision, related to their narrow scope, their dependence on official country notifications, and their lack of a formal internationally coordinated mechanism to contain international disease spread. The IHR 2005, which is firmly based on practical experiences, has broaden the scope of IHR 1969 to cover existing, new and re-emerging diseases, including emergencies caused by non-infectious disease agents.
