time periods of transmission between a primary case and a secondary case
in a transmission pair. Adapted from Zhao

Serial intervals of possible case pairs in (a)
COVID-19 and (b) MERS-CoV. Pairs represent a presumed infector and their
presumed infectee plotted by date of symptom onset (Althobaity
et al., 2022).
Figure 4

Fitted serial interval distribution for (a)
COVID-19 and (b) MERS-CoV based on reported transmission pairs in Saudi
Arabia. We fitted three commonly used distributions, Log normal, Gamma,
and Weibull distributions, respectively (Althobaity
et al., 2022).
