Superspread event

On 2020-03-19 a superspreading event most likely occurred in Scotland. 10 days later (2020-03-30) it started to super-spread through the community. A total of 44 copies of this genome (that represents the core of the outbreak), were reported in Gisaid, a proxy for primary transmissions, along with 181 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 2020-04-06, 17 days after it started, with 3296 sequences found in total.

The last sequence of the superspreading event was collected on 2020-05-18.
