Assumed incubation and generation-interval distributions in an analysis of the potential role of social distancing in mitigating the spread of coronavirus disease, South Korea, 2020*

Distribution Parameterization Priors Source
Incubation period distribution Gamma (µI, µ2I2) µI » gamma (6.5 d, 145); σ » gamma (2.6 d, 25) (6)
Generation-interval distribution Negative binomial (µG, θ) µG » gamma (5 d, 62); θ » gamma (5, 20) (7,8)

*Gamma distributions are parameterized using its mean and shape. Negative binomial distributions are parameterized using its mean and dispersion. Priors are chosen such that the 95% quantiles of prior means and standard deviations are consistent with previous estimates.
