Our work on superspreading has just been published https://www.nature.com/articles/s41591-020-1092-0, the preprint was posted a few months ago. https://twitter.com/bencowling88/status/1270549539154309121
Work done with @DillonCAdam @gmleunghku @Jessica_Y_Wong @TimTsang1 @SCauchemez
Key finding - between 23 January and 28 April 2020 in Hong Kong, we analysed contact tracing data and estimated that 19% of cases seeded 80% of all local transmission. For those interested in the dispersion parameter k it was 0.33 (95% CI: 0.14–0.98). https://www.nature.com/articles/s41591-020-1092-0
Clustering and superspreading potential of SARS-CoV-2 infections in Hong Kong

Placing close contacts of cases in mandatory government quarantine was very effective at terminating chains of transmission. https://www.nature.com/articles/s41591-020-1092-0
