Superspread event

On 2020-06-09 a superspreading event most likely occurred in Victoria. 19 days later (2020-06-28) it started to super-spread through the community. A total of 123 copies of this genome (that represents the core of the outbreak), were reported in Gisaid, a proxy for primary transmissions, along with 1114 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 2020-07-11, 32 days after it started, with 5768 sequences found in total.

The last sequence of the superspreading event was collected on 2020-07-31.
