Epidemiologicamente

Os modelos epidemilógicos mais simples assumem 4 equações para casos . Tem-se a seguinte configuração de eq. diferencial.

\[\begin{aligned} \frac{dS}{dt} & = -\frac{\beta IS}{N}\\ \\ \frac{dE}{dt} & = \frac{\beta IS}{N} - \kappa E\\ \\ \frac{dI}{dt} & = \kappa E - \gamma I\\ \\ \frac{dR}{dt} & = \gamma I \end{aligned}\]
