On 2021-03-09 a superspreading event most likely occurred in Germany. 34 days later (2021-04-13) it started to super-spread through the community. A total of 31 copies of this genome (that represents the core of the outbreak), were reported in Gisaid, a proxy for primary transmissions, along with 307 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 2021-04-17, 38 days after it started, with 58949 sequences found in total.
The last sequence of the superspreading event was collected on 2021-05-11.
The sequence of this event has been classified as Alpha.
