Infectious at Time Step n+1 in the Multi-Population SI Model

Available identifiers

equation to define the number of infectious individuals in the multi-population SI Model

Defining Formula: $I_{n + 1}^{i} = I_{n}^{i} + S_{n}^{i} \sum_{k = 1}^{K} \frac{α_{i k} Δ t}{N^{i}} I_{n}^{k}$
$I_{n}^{i}$ symbol represents Number of Infectious Individuals
$N^{i}$ symbol represents Total Population Size
$S_{n}^{i}$ symbol represents Number of Susceptible Individuals
$Δ t$ symbol represents Time Step
$α_{i k}$ symbol represents Contact Rate Between Two Groups
