Superspread event

On 2020-03-12 a superspreading event most likely occurred in Reykjavik. 2 days later (2020-03-14) it started to super-spread through the community. A total of 74 copies of this genome (that represents the core of the outbreak), were reported in Gisaid, a proxy for primary transmissions, along with 95 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 2020-03-24, 12 days after it started, with 1177 sequences found in total.

The last sequence of the superspreading event was collected on 2020-04-06.
