Parameters Used in the Stochastic Model
Parameter | Symbol | Distribution Used for Uncertainty Analysis |
Source (Reference) |
---|---|---|---|
Number of contacts during early phase | CEarly | Sampled from data | 2014 Liberia; Supplement 1† |
Number of contacts during late phase for nonsurvivors | CLate | Sampled from data, between 1 and 5 | Based on household size (22) |
Incubation phase duration (d) | η | Triangular (mode 8, range [5, 15]) | 3, 9, 15, 30 |
Late symptoms phase duration (d) | ψ | Uniform (range [1, 5]) | 18, 21, 31, 32 |
Overall symptom duration (d) | ν | Triangular (mode 8, range [5, 14]) | 18, 21, 26 |
Rate ratio of transmission risk | r | Evaluated | 1995 Zaire, 2000 Uganda; Supplement 1† (8, 9) |
Daily viral load stratified by survivorship | Vs(t) | Log normal* | 2000 Uganda (8) |
Viral load was measured based on the mean and SD counts of daily RNA copy levels over 14 d after symptom onset and are stratified by survivorship.
