On 2020-07-05 a superspreading event most likely occurred in Victoria. 4 days later (2020-07-09) it started to super-spread through the community. A total of 46 copies of this genome (that represents the core of the outbreak), were reported in Gisaid, a proxy for primary transmissions, along with 79 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 2020-07-15, 10 days after it started, with 3742 sequences found in total.
The last sequence of the superspreading event was collected on 2020-07-25.
