Notifiable disease
A notifiable disease is any disease that is required by law to be reported to government authorities. This collation of information allows the authorities to monitor the disease, and provides early warning of possible outbreaks.  Many governments have enacted regulations for reporting of both human and animal (generally livestock) diseases.

# Global

## Human
The World Health Organization's International Health Regulations 1969 require disease reporting to the organization in order to help with its global surveillance and advisory role.  The current (1969) regulations are rather limited with a focus on reporting of three main diseases: cholera, yellow fever and plague.
The revised International Health Regulations 2005 (scheduled to enter into force in June 2007) broadens this scope and is no longer limited to the notification of specific diseases.  Whilst it does identify a number of specific diseases, it also defines a limited set of criteria to assist in deciding whether an event is notifiable to WHO.

## Animal
The OIE (World Organisation for Animal Health) monitors specific animal diseases on a global scale.

Requirement for the notification of infectious diseases originated near the end of the 19th century.  The list started with a few select diseases and has since grown to about 30.  Currently disease notification for humans in the UK is regulated under the Public Health (Control of Disease) Act 1984 and Public Health (Infectious Diseases) Regulations 1988.  The governing body is the Health Protection Agency (Centre for Infections).

The act states that a police constable should be notified, however in practice a Defra divisional veterinary manager is notified and Defra will investigate.

# USA
In the past, notifiable diseases in the United States varied according to the laws of individual states. The Centers for Disease Control and Prevention and the Council of State and Territorial Epidemiologists (CSTE) also produced a list of nationally notifiable diseases that health officials should report to the CDC's National Notifiable Diseases Surveillance System (NNDSS). A uniform criteria for reporting diseases to the NNDSS was introduced in 1990.
