I think that May 2021 was when the Delta variant began to take hold: a sort of "second coming".

General news blurb:
The Delta variant is a variant of SARS-CoV-2, the virus that causes COVID-19. It was first detected in India in late 2020. The Delta variant was named on 31 May 2021 and had spread to over 163 countries by 24 August 2021.
