Superspread event

On 2020-07-28 a superspreading event most likely occurred in United Kingdom. 7 days later (2020-08-04) 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 179 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 2020-08-14, 17 days after it started, with 14969 sequences found in total.

The last sequence of the superspreading event was collected on 2020-09-22.
