Alert, response, and capacity building under the International Health Regulations (IHR)

Surveillance

The IHR require the rapid detection of public health risks, as well as the prompt risk assessment, notification, and response to these risks. To this end, a sensitive and flexible surveillance system is needed with an early warning function is necessary. The structure of the system and the roles and responsibilities of those involved in implementing the system need to be clear and preferably should be defined through public health policy and legislation. Chains of responsibility need to be clearly identified to ensure effective communications within the country, with WHO and with other countries as needed.
