Table 1. Parameter assumptions used in a coronavirus disease transmission model, Australia.

Parameter	Estimate or assumption	Justification
Fundamental assumptions
Doubling time	6.4 d	Estimated in from early case growth in Wuhan, China, from Wu et al. (11)
Incubation period	5.2 d	Based on Li et al. (12) and Lauer et al. (13)
Derived assumptions
R0	2.53	Based on latent and infectious periods, with doubling time 6.4 d (Appendix)
Latent (noninfectious) period	3.2 d	Assumes 2 d of presymptomatic transmission before completion of incubation period, based on contribution estimates from Ganyani et al. (14) and Tindal et al. (15)
Infectious period	9.68 d	Estimated, related to doubling time and incubation period (Appendix)
