Fundamental journal of mathematics and applications (Online), 4(2), 110 - 123. 10.33401/fujma.8632242645-8845https://doi.org/10.33401/fujma.863224https://hdl.handle.net/11616/85520https://search.trdizin.gov.tr/yayin/detay/450567In this study, using a system of delay nonlinear ordinary differential equations, we introduce a new compartmental epidemic model considered the effect of filiation (contamination) control strategy to the spread of Covid-19. Firstly, the formulation of this new SIuIaQR epidemic model with delay process and the parameters arised from isolation and filiation is formed. Then the disease-free and endemic equilibrium points of the model is obtained. Also, the basic reproduction number mathcalR0 is found by using the next-generation matrix method, and the results on stabilities of the disease-free and endemic equilibrium points are investigated. Finally some examples are presented to show the effect of filiation control strategy.eninfo:eu-repo/semantics/openAccessArticle4211012310.33401/fujma.863224450567
