2022年疫情會結束嗎?

更新時間:2022-03-02 02:09:45作者:admin2

縱觀全球疫情總體情況,不同國家抗擊疫情的態度和力度存在差異,因此不同國家的疫情也存在差異。專家表示,在抗擊疫情中,要采取科學、人性化的免疫措施,達到免疫效果,疫苗發揮的作用最好。各國在疫苗和藥物研發方面不斷取得進展,中國的疫苗接種工作從未停止。然而,以現有的醫療設備和藥物,很難在短時間內消除病毒。全人類至少需要2-3年才能實現群體免疫。只有建立了全面的免疫屏障,才有希望控制疫情的爆發。因此,在實現群體免疫的基礎上,全人類只能控制疫情發展,而不能根除病毒。因此,全人類暫時無法在2022年徹底結束疫情,只能暫時控制疫情。

別做夢了,中國還好,別的國家紅旗飄飄,隨時有傳染的可能
