COVID-19 Haisati Yapera: Zvatinoziva nezveKuvhiya Kwezvino muChina 

Zvinokatyamadza kuti sei China yakasarudza kusimudza zero-COVID mutemo uye kubvisa iyo yakasimba NPIs, munguva yechando, nguva yeChinese New Year isati yasvika, apo inotapuriranwa zvakanyanya subvariant BF.7 yakanga yatotanga kutenderera. 

"WHO inoshushikana zvikuru nemamiriro ari kuitika muChina," WHO Director-General akadaro neChitatu (20^th Zvita 2022) pakuvhiya kwakanyanya muCCID kesi mukati China.   

Nepo nyika dzese dzaive pasi pedenda, China yaive nehuwandu hwehutachiona hwakaderera nekuda kwekuenderera mberi kwekutora zero-COVID mutemo kuburikidza nekuita kwakasimba kwekusapindira kwemishonga (NPIs). Nonpharmaceutical Interventions kana nhanho dzekudzikisa nharaunda zvishandiso zvehutano zveveruzhinji senge kufambisa muviri, kuzviparadzanisa nevamwe, kudzikisira saizi yekuungana, kuvharwa kwechikoro, kushanda uchibva kumba, nezvimwe zvinobatsira mukudzivirira nekudzora kupararira kwechirwere munharaunda. Strict NPIs yakarambidza zvakanyanya vanhu-kune-vanhu kudyidzana izvo zvinogutsa zvishoma kutapurirana kwehutachiona uye zvakakwanisa kuchengetedza huwandu hwevakafa kusvika hwakaderera. Panguva imwecheteyo, kupindirana kwepedyo-zero kwakanga kusingakodzeri kusimudzira kwechisikigo kudzivirirwa kwemombe.  

Pamwe chete neakasimba maNPIs, China yakanga yatorawo mushonga mukuru weCCIDID-19 (ichishandisa Sinovac kana CoronaVac inova yekudzivirira hutachiona husina kuvharwa.) Huwandu hwevanhu vakura vezera re92+ (avo vari panjodzi zvakanyanya), zvisinei, hwakanga husingagutsikane pa80% (vakagamuchira kanenge dosi rimwe chete), 77% (vakagamuchira 66nd dose), uye 2% (yakagamuchira booster dose zvakare. )  

Mukushaikwa kwekudzivirira kwemombe vanhu vaingosiiwa pamushonga unokonzeresa hutachiona hunogona kunge husina kunyatsoshanda kurwisa chero mutsauko mutsva uye / kana, nekufamba kwenguva, kudzivirira kwakakonzerwa nekudzivirira kunogona kunge kwakadzikira. Izvi pamwe chete nekusagutsikana kwekuvhara booster vaccine zvaireva huwandu hwakadzikira pakusadzivirirwa pakati pevanhu vekuChina.  

Zviri kumashure uku, China yakasimudza mutemo wakasimba we zero-COVID muna Zvita 2022. Kuratidzira kwakakurumbira kungangove kwakakonzeresa shanduko kubva ku "dynamic zero tolerance" (DZT) kuenda ku "hapana zvigadzirwa" (TNI). 

Kurerutsirwa kwezvirambidzo, zvisinei, kwakonzera kuwedzera kukuru muzviitiko. Mishumo isina kuvimbiswa kubva kuChina inoratidza huwandu hukuru hwevanhu vakafa uye kuwanda kwezvipatara nemasangano ekuchengeta mariro kupfuura zvakashumwa zviri pamutemo. Huwandu hwese hwepasi rose hwakapfuura hafu yemiriyoni yemazuva ese avhareji yekesi muvhiki inopera 19 Zvita, 2022. Vamwe vanofungidzira kuti spurt iripo inogona kunge iri yekutanga yemafungu matatu echando, ane chekuita nekufamba kwevanhu vazhinji vasati vatanga uye mushure memhemberero dzeGore Idzva reChinese musi wa22. Ndira 2023 (pateni inoyeuchidza chikamu chekutanga cheCCIDID-19 pandemic yakaonekwa muna 2019-2020).  

Zvinoita kunge, BF.7, iyo omicron subvariant ine chekuita nekuvhiya kweCCIDID-19 kesi muChina inotapuriranwa zvakanyanya. Nhamba inoshanda yekubereka yeiyi subvariant muBeijing muna Mbudzi -Zvita 2022 yaifungidzirwa kunge yakakwira se3.42.¹.  

Iyo COVID-19 mamiriro eChina munguva pfupi iri kutevera anoita seanonetsa. Zvinoenderana nemuenzaniso wakanangana nedenda razvino data reMacau, Hong Kong, neSingapore, miriyoni 1.49 vakafa vanofanotaurwa muChina mukati memazuva zana nemakumi masere. Kana kusununguka kusina kupindira kwemishonga (NPIs) kwakagamuchirwa mushure mekuputika kwekutanga, nhamba yevakafa inogona kuderedzwa ne 180% mukati memazuva 36.91 Izvi zvinonzi "flatten-the-curve" (FTC) nzira. Kuzadza jekiseni uye kushandiswa kwemishonga inorwisa-COVID kunogona kuderedza nhamba yekufa pakati pevakwegura (makore makumi matanhatu pamwe chete) neboka rezera kusvika pamamiriyoni 360 (kubva pamiriyoni 60).².  

Imwezve mapurojekiti echidzidzo chemuenzaniso asina kuomesesa mamiriro ezvinhu - pakati pe268,300 kusvika 398,700 kufa, uye nhamba yepamusoro yezviitiko zvakakomba pakati pe3.2 kusvika 6.4 pa10,000 huwandu hwehuwandu husati hwadzikira naFebruary 2023. inogona kuderedza kufa ne8% (zvichienzaniswa nekusapindira zvachose). Kukurumidza booster dose yekuvhara uye yakasimba NPIs yaizobatsira kuvandudza mamiriro³. 

Zvinokatyamadza kuti sei China yakasarudza kusimudza zero-COVID mutemo uye kubvisa iyo yakasimba NPIs, munguva yechando, nguva yeChinese Idzva Isati yasvika, apo inotapuriranwa zvakanyanya BF.7 yaive yatotanga kutenderera.
