One–dimensional logistic maps are considered as a basic and effective model for epidemic research and prediction in a closed environment. The results obtained from logistic models are often agreed with actual data gathering in isolated or semi–isolated communities. However, in a flat world, countries and territories are no longer closed in every sense, transactions with human involvement such as trading, transporting, ... are inevitable. In this context, recent outbreaks of epidemics in the world have been out of the forecast and outside the framework provided by an one–dimensional logistic map. An extended version of the logistic map so–called the matrix logistic map where growth rate and variables instead of ordinary numbers are replaced by corresponding matrices of which diagonal elements and off--diagonal elements characterize the native processes in each subsystem and the effective interactions between component systems, respectively. In that manner, the proposed extended model allows investigating changes of each component system in the presence of neighboring systems. In this report, the simplest case consisting of two subsystems is studied.
