Estimation of early phase local-to-local transmissibility and importation hazard of Coronavirus Disease 2019 (COVID-19) epidemic under assorted containment measures in Hong Kong

[...]our estimates of R0 may be affected by the potential recall bias of dates of symptom onsets, by individual-level variability in transmission, and by the potential presence of super-spreaders. [...]other variables in addition to containment measures, such as increasing community engagement in personal protective measures [6], may explain the reduced transmissibility. [...]this study cannot tease apart the combined effect of assorted government containment strategies to measure the individual policy contribution in reducing local disease transmissibility and importation hazard.Financial support This work has been partially supported by Research Fund for the Control of Infectious Diseases, Hong Kong (Number: INF-CUHK-1); General Research Fund (Number: 14112818); Health and Medical Research Fund (Ref: 18170312); Wellcome Trust (UK, 200861/Z/16/Z).
