Superspread event

On 2021-03-22 a superspreading event most likely occurred in Denmark. 13 days later (2021-04-05) it started to super-spread through the community. A total of 31 copies of this genome (that represents the core of the outbreak), were reported in Gisaid, a proxy for primary transmissions, along with 55 genomes that are one-step mutation with respect to the core genome (a proxy for secondary transmissions). The signature for the likely superspreading event ends at about 2021-04-05, 13 days after it started, with 18787 sequences found in total.

The last sequence of the superspreading event was collected on 2021-04-26.

The sequence of this event has been classified as Alpha.
