Distribution of (a) incubation period, where $\alpha$ is the shape, and $\theta$ is the scale of Gamma distribution, and (b) recovery periods (Lauer et al., 2020, Verity et al., 2020). In (a), solid line shows the best fit to data from Lauer et al. (2020), the dashed line is the closest fit to Gamma distribution with integer parameters.
