Superspread event

On 2020-05-13 a superspreading event most likely occurred in Victoria. 40 days later (2020-06-22) it started to super-spread through the community. A total of 699 copies of this genome (that represents the core of the outbreak), were reported in Gisaid, a proxy for primary transmissions, along with 1496 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 2020-07-26, 74 days after it started, with 7237 sequences found in total.

The last sequence of the superspreading event was collected on 2020-08-09.
