These techniques give more accurate and appropriate results. Existence and uniqueness have been developed with the help of fixed-point theory results. Numerical simulations are done from the developed algorithm of the model to elaborate the effect of fractional values and justify the theoretical results. Such kind of analysis will be useful for further investigation of epidemic diseases, and also provide a better understanding of disease dynamics to overcome the effect of disease in a community.eninfo:eu-repo/semantics/openAccessHuman LiverAtangana-Baleanu in Caputo SenseFractal FractionalMittag-Leffler KernelFixed Point TheoremsArticle314Q1WOS:000979617400002Q12-s2.0-8515798133010.1142/S0218348X23400479
