Abstract
The theory of the basic reproduction ratio \(R_{0}\) and its computation formulae for almost periodic compartmental epidemic models are established. It is shown that the disease-free almost periodic solution is stable if \(R_{0}<1\), and unstable if \(R_{0}>1\). We also apply the developed theory to a patchy model with almost periodic population dispersal and disease transmission coefficients to obtain a threshold type result for uniform persistence and global extinction of the disease.
