Abstract

Using two early transmission chains in Hong Kong, the estimated R and k were 1.34 [95% credible interval (CrI): 0.94–2.19] and 0.33 (95%CrI: 0.17–0.62), respectively, inferring 20.3% (95%CrI: 12.7–29.6%) cases were responsible for 80% of the transmissions of the Omicron epidemic. Compared with Omicron BA.1, Omicron BA.2 had a greater superspreading potential.
