Strengthening health security by implementing the International Health Regulations (2005)

A global system for alert and response

WHO/C. Black

When a significant public health event takes place, WHO’s comprehensive global alert and response system ensures that information is available and response operations are coordinated effectively.

The system includes the following functions:

- Event-based surveillance, multi-hazard rapid risk assessment and event-based risk communications;
- Critical information and communications platforms for decision support; and
- Operations and logistics platforms for any WHO response to international public health risks.
