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　R0e＜1.　As　a　consequence,　we　derive　the　relationships　among　the　stochastic　persistence　index　R0s,　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　R0＜R0e＜1　reveals　that,　when　the　intensities　of　the　white　noises　are　enhanced,　the　value　R0e　triggers　the　stochastic　extinction.　©　2024　Elsevier　Ltd
