We　propose　a　stochastic　HCV　model　with　protection　awareness　and　exposed-acute-chronic　phases　in　this　study.　First　of　all,　we　show　that　the　stochastic　HCV　model　admits　a　unique　global　positive　solution　for　any　given　positive　initial　values.　Then,　we　verify　that　HCV　model　has　a　unique　stationary　distribution　under　the　sufficient　criterion　R0s＞1,　which　indicates　that　HCV　transmission　undergoes　the　persistence　in　the　long　term.　Furthermore,　we　derive　the　sufficient　conditions　for　HCV　extinction　under　the　condition　R0e0s,　the　stochastic　extinction　index　R0e　and　the　threshold　(the　basic　reproduction　number　R0)　of　the　model　without　fluctuations.　The　condition　R0＞R0s＞1　reveals　that　the　existence　of　the　white　noises　triggers　the　less　stochastic　persistence　index.　While,　the　condition　R00e0e　triggers　the　stochastic　extinction.　©　2024　Elsevier　Ltd
