Several factors, such as disease behaviour and virus characteristics, determine when there is a shift between Alert Levels, with the following set of 6 Phase Levels to the WHO Pandemic Alert System:
Level 1: 'Inter-Pandemic Phase'
- There is Low Risk of Human Cases
Level 2: 'Inter-Pandemic Phase'
- There is Higher Risk of Human Cases
Level 3: 'Pandemic Alert'
- No or Very Limited Human-to-Human Transmission
Alert Level continued below...
|
Level 4: 'Pandemic Alert'
- Evidence of Increased Human-to-Human Transmission
Level 5: 'Pandemic Alert'
- Evidence of Significant Human-to-Human Transmission
Level 6: 'Pandemic'
- Efficient and Sustained Human-to-Human Transmission
A shift between Levels triggers the WHO, and other World Bodies and Governments, into implementing specific recommendations and measures to meet the needs of such changes.
