Superspread event

On 2021-04-07 a superspreading event most likely occurred in England. 5 days later (2021-04-12) it started to super-spread through the community. A total of 30 copies of this genome (that represents the core of the outbreak), were reported in Gisaid, a proxy for primary transmissions, along with 320 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 2021-04-16, 9 days after it started, with 23518 sequences found in total.

The last sequence of the superspreading event was collected on 2021-05-11.

The sequence of this event has been classified as Alpha.
