Model Penyebaran Penyakit Malaria Dengan Imigran Terinfeksi

ABSTRACT This final project discusses the analysis of mathematical models of malaria transmission with infective immigrants. This model uses the systems of differential equations of the model of susceptible, infected, recovered (SIR) with two population. The observed model has only an endemic equilibrium point. Stability analysis is performed using Routh-Hurwitz criteria. Furthermore, simul…
