Superspread event

On 2020-10-11 a superspreading event most likely occurred in England. 60 days later (2020-12-10) it started to super-spread through the community. A total of 87 copies of this genome (that represents the core of the outbreak), were reported in Gisaid, a proxy for primary transmissions, along with 1076 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 2020-12-21, 71 days after it started, with 80302 sequences found in total.

The last sequence of the superspreading event was collected on 2021-01-16.

The sequence of this event has been classified as Alpha.
