  1. The time-dependent reproduction number \(\left({\text{R}}_{t}\right)\) at CP is 1.011 for Guinea and 1.028 for Sierra Leone. Additionally, the other values of factors are \(\frac{\sigma E}{\upgamma I} = 1.0267\), \(\frac{1}{\left(1+E/S \right)}\approx 1\) for Guinea with a total population (N) of 11,745, and \(\frac{\sigma E}{\upgamma I} = 1.0351\), \(\frac{1}{\left(1+E/S \right)}\approx 1\) for Sierra Leone with \(N=6092057\).
