Superspread event

On 2021-02-08 a superspreading event most likely occurred in Canada. 5 days later (2021-02-13) it started to super-spread through the community. A total of 35 copies of this genome (that represents the core of the outbreak), were reported in Gisaid, a proxy for primary transmissions, along with 69 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 2021-02-19, 11 days after it started, with 602 sequences found in total.

The last sequence of the superspreading event was collected on 2021-03-08.

The sequence of this event has been classified as Alpha.
