Superspread event

On 2020-09-10 a superspreading event most likely occurred in United Kingdom. 11 days later (2020-09-21) it started to super-spread through the community. A total of 64 copies of this genome (that represents the core of the outbreak), were reported in Gisaid, a proxy for primary transmissions, along with 157 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 2020-09-28, 18 days after it started, with 23482 sequences found in total.

The last sequence of the superspreading event was collected on 2020-10-17.
