EPI and ERI graphs
Notation: EPI -Epidemic Index; ERI - Epidemic Risk Index.
23 March - 5 May 2021
The pandemic is still surging..
1 January - 24 April 2021
the 2nd pandemic wave is ongoing.
1 March - 16 April 2021
The pandemic is moving in a wrong direction, i.e. it is surging. EPI > 1 since 8 March. ERI >1 since 29 March, which means the pandemic has moved into a danger/red/high-risk zone.
1 January - 16 March 2021
Since 8 March, EPI>1. The first signs of the pandemic starting to surge? Another wave is emerging? Or just a random spike?
Since 17 February, the Risk Index/number ERI < 1. If R number/EPI will stay > 1, then the risk number will also go up.
1 - 29 January 2021
R number/EPI < 1. The Risk number/ERI remains high but decreasing.
1 September 2020 - 29 January 2021
1 July 2020 - 29 January 2021
The pandemic moved into another wave without reaching a safe zone (where the Risk index ERI < 1).
