Daftardar-Gejji and Jafari method for solving SIR Epidemic model / Mat Salim Selamat, Siti Adilah Shuib and Nur Liyana Nazari

In this letter, the classical susceptible-infectious-removed (SIR) epidemic models has been solved using Daftardar-Gejji and Jafari method (DJM) (Daftardar-Gejji and Jafari, 2006). The SIR model aims to predict the number of individuals who are susceptible to infection, are actively infected, or have recovered from infection at any given time. In this study, DJM was applied to solve the epidemic model. The results show that the reliability of the results is limited to certain parameters only i.e B = 0.01 and Y = 0.02. Therefore, DJM is not a method that can be used in all situations.
