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).
