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) |
