Zvinogona kunetsa zvakanyanya pane kugadzira zvekudzivirira
BENJAMIN PINSKY, STANFORD Yunivhesiti

Nemusi weChina, ndege yeIrish Aer Lingus yakazivisa kuti yaizotumira ndege dzayo shanu huru kuChina zuva rega rega kunotora michina, kusanganisira zviuru zana zvekuyedza pasvondo, vachibatana nenyika dzakawanda dzichidzosera ndege dzekutengesa semidziyo yekutakura vanhu.

Asi zvinonzi kunyangwe nekusundirwa kwakadaro, China haina kukwanisa kuzadzisa zvinodiwa nepasi rose zvematest kits, nemutengesi mumwe achitsanangura kudiwa kwepasirese se "zvisingaperi".

Huaxi Securities, kambani yekuChina yekudyara, svondo rapfuura yakafungidzira kudiwa kwepasirese kwematest kits anosvika zviuru mazana manomwe emayuniti pazuva, asi nekuda kwekushaikwa kwemiedzo kuchiri kukonzera ingangoita hafu yepasi kushandisa zvivharo zvekuvharisa, nhamba iyi inoita seyakachengetedza.Uye nekupihwa kutya pamusoro pevatakuri vehutachiona vasingaratidzi zviratidzo, munyika yakanaka, munhu wese aizoedzwa, uye pamwe kanopfuura kamwe.

"Kana hutachiona hwangove husina kuvharwa, handina chokwadi chekuti nyika, kunyangwe yakarongeka zvizere, ingadai yakaedzwa pamatanho avanoda kuyedza," akadaro Ryan Kemp, director kuZymo Research, mugadziri wekuAmerica wemolecular biology. maturusi ekutsvagisa, ayo akapa "zana muzana kutsigira kuedza kweCovid-19, kuunganidza kambani yese kuti itsigire".

Rwiyo, kuCAIVD, anofungidzira kuti kana ukabatanidza kugona kwemafemu ane rezinesi kuChina neEuropean Union, bvunzo dzakakwana dzinogona kuitwa zuva rega rega kushandira vanhu mamirioni matatu nemusanganiswa wePCR uye bvunzo dzeantibody.

Kubva nemusi weChina, US yakaedza vanhu zviuru mazana mashanu nemakumi mashanu nemazana mashanu, White House yakati.Stephen Sunderland, mumwe wake akatarisana nehunyanzvi hwekurapa kuShanghai-based LEK Consulting, anofungidzira kuti kana US neEU dzaizotevera mwero wakafanana wekuyedzwa seSouth Korea, paizodiwa mamirioni mana ebvunzo.

Tichifunga izvi, hazvigoneke kuti hunyanzvi hwekugadzira pasi rose hunogona kusangana nezvinodiwa, munguva pfupi iri kutevera.

Midziyo yekuyedza "yakafanana nekugadzira masiki", akadaro kunobva kuBGI, uyo akayambira kuti hazvigoneke kuti mafemu asiri nyanzvi akaita seFord, Xiaomi kana Tesla agadzire makiti ebvunzo, achipihwa kuoma uye zvipingamupinyi kupinda.

Kubva pahuwandu hwazvino hwekambani hwe600,000 pazuva, "hazvigoneke kuwedzera fekitori" nekuda kwekukakavadzana kwemaitiro, akadaro BGI source.Kugadzirwa kwemidziyo yekuongorora muChina kunofanirwa kusangana nemiyero yekiriniki yakasimba uye nekudaro nzira yekubvumidza nzvimbo nyowani inotora pakati pemwedzi mitanhatu negumi nemiviri.

"Zvakaoma kuwedzera zvinobuda kamwe kamwe, kana kutsvaga kumwe kwaibva, pane zvemasiki," akadaro Poon.“Fekitori iyi inofanirwa kupihwa mvumo uye inofanirwa kunge iine mwero wepamusoro.Zvinotora nguva.kuita izvozvo.”

Song akati kune chimwe chinhu chakakomba senge coronavirus, kuve nekiti yekuyedza yakabvumidzwa neChina inogonanyanya kuoma kupfuura zvamazuva ose.“Hutachiona hunotapukira zvakanyanya uye manejimendi epecimenkuomarara, zvakaoma ... kuwana masampuli ekuona zvizere uye kuongorora zvigadzirwa," vakatungamira.

Denda iri rakanganisawo kuwanikwa kwezvinhu zvakashandiswa mumidziyo, zvichikonzera kushomeka pasi rese.

Semuyenzaniso, chigadzirwa chakagadzirwa neZymo chekutakura uye kuchengeta masamples ebhayoloji chinowanikwa mune zvakawanda - asi femu iri kuona kushomeka kwemaswabhu akareruka anodiwa kuunganidza masampuli.

Mhinduro yeZymo ndeyekushandisa swabs kubva kune mamwe makambani."Zvisinei kune zvinhu zvishoma, zvekuti tanga tichipa zvigadziriso kumasangano kuti aenderane nemasevhisi aainawo," akadaro Kemp, achiwedzera kuti, muchikamu chezvekupihwa kwekurapa kwepasirese, akawanda epasi rose akagadzirwa. nekambani yekuItaly yeCopan, munharaunda yeLombardy yakabatwa nehutachiona.

Benjamin Pinsky, uyo anomhanyisa rabhoritari huru yekoronavirus kuchamhembe kweCalifornia kubva kuStanford University, akati "pakave nematambudziko makuru nekupihwa kwezvimwe zvigadziriso uye zvinodyiwa"
inoshandiswa pakuongorora PCR.

Kunyange Pinsky akagadzira bvunzo yePCR, anga achinetseka kutsvaga zvekushandisa, zvinosanganisira swabs, hutachiona hwekutakura midhiya, PCR reagents uye kits yekubvisa.“Zvimwe zvacho zvakaoma kuwana.Pane kunonoka kubva kune mamwe makambani anogadzira maprimers uye probes, "akawedzera."Zvinogona kuoma zvakanyanya pane kugadzira
midziyo yekuzvidzivirira nayo.”

Zhang muNanjing ine simba rekugadzira zviuru makumi matatu zvePCR zvekuyedza pazuva, asi inoronga kutenga mimwe michina miviri kuti ikwidze kusvika zviuru zana.Asi zvinhu zvekunze zvakaoma, akadaro."Makambani anopfuura mashanu kuChina anogona kutengesa PCR test kits mhiri kwemakungwa nekuti zvekufambisa zvinoda nharaunda iri minus 20 degrees Celsius (68 degrees Fahrenheit)," akadaro Zhang."Kana makambani akakumbira inotonhora chain logistics kutakura, mubhadharo wakatokwira kupfuura zvinhu zvavanogona kutengesa."

Mafemu eEurope neAmerica anowanzo tonga musika wepasi rose wemidziyo yekuongorora, asi ikozvino China yave hubhu yakakosha yezvekushandisa.

Panguva yekuperevedza kwakadaro, zvakadaro, nyaya muSpain inosimbisa kuti pakati pekukakavadzana kwekukurumidzira kwezvinhu zvekurapa izvo zvave kushomeka uye zvakakosha seguruva regoridhe gore rino, mutengi anofanirwa kugara akangwarira.
