The estimates of the basic reproduction number ${\mathcal{R}}_0$ for three largest clusters together with the corresponding 95% confidence intervals (CI-s). The results are reported for two pairs of generation interval distribution parameters $\widehat{\mu }$ and $\widehat{\sigma }$ reported by two studies.

Cluster	$\widehat{\mu }$	$\widehat{\sigma }$	${\widehat{\mathcal{R}}}_0$ &95% CI	$\widehat{\mu }$	$\widehat{\sigma }$	${\widehat{\mathcal{R}}}_0$ &95% CI
First	5.20	1.72	1.31 (1.12; 1.52)	3.95	1.51	1.23 (1.09; 1.37)
Second	5.20	1.72	1.47 (1.1; 1.98)	3.95	1.51	1.34 (1.07; 1.68)
Third	5.20	1.72	1.48 (1.16; 1.94)	3.95	1.51	1.35 (1.12; 1.65)
