Multiple strains of tuberculosis is one of the transmission mechanisms of tuberculosis. In this article, we discuss two-strain tuberculosis model include drug-sensitive strains and drug-resistant strains. The model is a non-linear system of differential equations that has six variables. The model analysis technique used to resolve the model is the homotopy perturbation method. The solution is the sum of an infinite series. By comparison of result polynomials of different degrees, it is found that the more terms of polynomial approach to the exact solution. © 2023 Author(s).
