Infectious at Time Step n+1 in the SIS Model with Births and Deaths

Available identifiers

MaRDI QIDQ6674395

equation to define the number of infectious individuals in the SIS Model with births and deaths

Defining Formula: $S_{n+1}=S_n(1-\frac{\alpha \Delta t}{N}{I}_n)+\gamma \Delta t{I}_n+\beta \Delta t(N-S_n)$

$I_n$ symbol represents Number of Infectious Individuals

$N$ symbol represents Total Population Size

$S_n$ symbol represents Number of Susceptible Individuals

$\Delta t$ symbol represents Time Step

$\alpha$ symbol represents Contact Rate

$\beta$ symbol represents Birth Rate

$\gamma$ symbol represents Relative Removal Rate
