Superspread event

On 2020-09-20 a superspreading event most likely occurred in Abu Dhabi. 9 days later (2020-09-29) it started to super-spread through the community. A total of 40 copies of this genome (that represents the core of the outbreak), were reported in Gisaid, a proxy for primary transmissions, along with 18 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 2020-09-29, 9 days after it started, with 146 sequences found in total.

The last sequence of the superspreading event was collected on 2020-10-27.
