Riaan Ngesikhathi esifanayo, ngemva kokuhlolwa ngempumelelo esikhumulweni sezindiza i-JFK saseNew York, iCenters for Disease Control and Prevention iphishekela izingxoxo nezinkampani zezindiza kanye neziphathimandla zamachweba ukuze ziqale ukuqoqa amasampula emanzini angcolile ezindiza zamazwe ngamazwe ezithatha isikhathi eside ngemva kokuba sezifikile.
Uhlelo oluncane kodwa olukhulayo lweTraveller Genomic Surveillance, oluqhutshwa yi-CDC enefemu ye-biotech kanye nenkampani eqoqa amasampula, lubonwa yizikhulu zokuphatha kanye nochwepheshe bezempilo yomphakathi njengengxenye yoguquko lwengqalasizinda ye-biosafety – kanye nepulangwe elibalulekile lokuphepha kuzwelonke. inkathi yangemva kobhubhane. Njengoba inweba ngokwendawo futhi ibheka amagciwane amasha, ingasebenza njengesistimu yesixwayiso yangaphambi kwesikhathi lapho amagciwane ayingozi kanye namagciwane, emvelo noma ngenye indlela, engena khona ezweni.
“Njengoba sine-radar yokubheka izindiza ukuze siqinisekise ukuthi siyazi ukuthi yini ezayo ezweni lethu, noma sithatha ama-swabs namasampula ukuqinisekisa ukuthi umuntu ohamba ngezokuphepha akanazo iziqhumane ezandleni zakhe, lokhu kuyinto efanayo namagciwane. noma amagciwane noma amagciwane,” kusho uMatthew McKnight, umphathi jikelele e-Ginkgo Bioworks, ophiko lwakhe lwe-biosecurity kanye nezempilo yomphakathi, i-Concentric ka-Ginkgo, ebambisene ne-CDC ohlelweni kanye ne-XpresCheck.
Ezinsukwini zokuqala zika-Omicron, uhlelo luthole kokubili ama-BA.2 kanye ne-BA.3 angaphansi kwamasonto ngaphambi kokuthi abonakale kwenye indawo e-US Kuphrojekthi yokuhlola e-JFK, lapho abasebenzi baqoqa khona amasampula amanzi angcolile ezindizeni ezifika zivela eYurophu ngo-August futhi NgoSepthemba, uhlelo luhlonze ukulandelana okufanayo kwe-SARS-CoV-2 emanzini angcolile ayezungeza kakhulu emazweni lapho izindiza zisuka khona.
Selokhu lolu hlelo lwanda ngenxa yokuqubuka kodlame lwaseChina, i-CDC ithi ayikatholi ukuhluka okusha kumasampula egciwane abagibeli abavela eChina. “Kuze kube manje, ngokuqinisekisayo, sibona i-BA.5.2 kanye ne-BF.7 – imigqa emibili eye yabikwa ivela e-China, engeyona into entsha noma ekhathazayo,” kusho uCindy Friedman, inhloko ye-CDC’s Travelers’ Health Branch.
Lolu hlelo manje luhlanganisa izindiza ezingaba ngu-500 ngosuku ezivela emazweni angaba ngu-30. Kungokuzithandela: abagibeli abafikayo, ngemva kwamasiko, bangama edokodweni, baphendule imibuzo embalwa, futhi banikeze izisebenzi zohlelo i-swab yamakhala. Amasampula abe esethunyelwa elebhu ekunethiwekhi ye-Ginkgo ukuze ahlolwe; uma benethemba, i-Ginkgo iyazilandelanisa, izihlaziye, futhi ibike lolo lwazi ku-CDC, eyabelana ngalo kusizindalwazi somhlaba wonke kanye isilandeleli sedatha ye-COVID yesikhungo.
Ukubamba iqhaza kukhule ngokushesha kusukela i-CDC yaqala ukuqapha izindiza eziningi ngenyanga edlule. Isonto lika-Jan. 2, isibonelo, abagibeli abangaba ngu-4,500 kuzo zonke izikhumulo zezindiza eziyisikhombisa lapho uhlelo lusebenza khona manje bazinikele ekunikezeni amasampula, kusukela cishe ku-2,700 ngesonto eledlule.
Nokho, uma kubhekwa ithrafikhi yendiza yamazwe ngamazwe, lokho kusephansi kakhulu, futhi kunobubi bemvelo bokuphendukela eqenjini elizikhethela lona okungenzeka ukuthi liqaphe kakhulu nge-Covid.
“Ukuthembela kubantu ukuthi bavolontiye ukuze bahlolwe i-Covid kulesi sigaba sobhubhane kuyinselelo ngempela,” kusho uMegan Diamond, umqondisi wokubambisana kwezempilo emhlabeni wonke eRockefeller Foundation. “Uzoba nesampula elichemile. Abantu abakwenzayo ngabantu okungenzeka ukuthi benze i-antigen test ngaphambi kokuba bahambe ekhaya. ”
Ukunweba ukuze kufakwe amasampula amanzi angcolile ajwayelekile ezikhumulweni zezindiza kuzonweba ilensi yososayensi ezimbungwini ezingena endaweni yase-US. Akudingi ukuthengwa ngabagibeli, futhi ukusebenza kudinga abasebenzi abambalwa endaweni eyinkimbinkimbi yesikhumulo sezindiza, ngakho kubiza kancane.
Ekugcineni, i-CDC ibona womabili ama-prongs ohlelo lokuqapha abahambi – ukuqoqwa kwesampula ngokuzithandela kanye nokuqapha kwamanzi angcolile – ukuxhumanisa namanye amazwe aqala ukwenza into efanayo, ezondla ohlelweni lomhlaba wonke olunikeza isithombe sesikhathi sangempela sokuthi abahambi zithwele izifo emhlabeni wonke.
“Sifuna ukwazi ukuthi okuhlukile kuvela nini noma kuvela nini ngokushesha, futhi lawa angamathuluzi azosiza ukuphendula leyo mibuzo,” kusho u-Tom Inglesby, umqondisi we-Johns Hopkins Center for Health Security e-Bloomberg School of Public Health. “Ngaphandle kwalokho, silindele lezo zinto ukuthi zibonakale emadolobheni … Lokhu kuzama ukukuqhubekisela phambili ukuze sithole isiginali esheshayo.”
‘Iphupho lengqalasizinda ye-biosecurity’
Uhlelo lwe-CDC luhambisana nombono obanzi wabaphathi be-Biden wokusebenzisa izifundo ezifundwe ngesikhathi sodlame lwe-Covid ukuqinisa ukuzivikela kwezwe.
Abaphathi sebevele besebenzisa inethiwekhi esabalele yamalabhorethri ezempilo yomphakathi, izindawo zokuhlola, kanye nokubhekwa kwamanzi angcolile asekhaya okwasungulwa ngesikhathi sodlame ukuqoqa amasampula egciwane futhi awahlaziye ukuze afunde ukuthi yiziphi izinhlobo ze-SARS-CoV-2 ezisakazwa e-US I-White House ifuna. ukubona leyo nethiwekhi, ehlanganisa uhlelo lwe-Traveller Genomic Surveillance, iqala ukusebenza ukuze ibheke ezinye izinsongo.
Ukwakhela kuleyo ngqalasizinda kuzoba “baluleke kakhulu ekuvikelekeni kwesikhathi eside kwezwe lethu,” Umxhumanisi Wezimpendulo eWhite House Covid-19 u-Ashish Jha utshele iPOLITICO.
Uhlelo lwe-CDC seluvele lwengeze igciwane elisha ohlwini lwayo lokubuka: umkhuhlane. Kulobu busika, uma kubhekwa isikhathi somkhuhlane esingajwayelekile emazweni amaningana, uGinkgo waqala ukuhlola amasampula abagibeli amagciwane omkhuhlane A no-B, ngaphezu kwe-SARS-CoV-2. Yabelane ngamasampula amahle ne-CDC ukuze ilandelelane – ulwazi olungase lusetshenziswe ekuthuthukisweni komgomo wesizini elandelayo yomkhuhlane.
Iwuhlobo lwe-pivot olungenza ukwandisa uhlelo ezikhumulweni zezindiza eziningi kanye namanzi angcolile endiza kube yimpahla kwezokuphepha kuzwelonke ngemuva kokuphela kobhubhane, kusho uMcKnight kaGinkgo.
“Ufuna ukwazi ukubona izinhlobo zofuzo ze-Covid. Ufuna ukwazi ukubona okuhlukile kofuzo kwamanye amagciwane asongelayo angase avele, aziwayo futhi angaziwa. Futhi ufuna ukuba nekhono lokubheka izinto ezikhiqizwe ngephutha – noma izinto ezikhishwe ngenhloso – bese ungazisebenzisa ezindaweni lapho ukhathazekile ngokuvela kwezinto,” kusho yena. “Lelo yiphupho lengqalasizinda ye-biosecurity. Futhi kungenzeka ngokuphelele. ”
Selokhu iBeijing iphakamise kungazelelwe inqubomgomo yayo ethi “zero-Covid” ngenyanga edlule, amanye amazwe amaningana nawo aseqalile ukucabanga kabanzi ngolwazi lwebhayoloji oluhlala ezindaweni zangasese zezindiza.
I I-European Union isanda kusho ibheka ukuhlolwa nokulandelana kwamanzi angcolile ezindizeni nasezikhumulweni zezindiza, futhi kule nyanga Inkampani yaseCanada i-LuminUltra imemezele ukuthi yethula iphrojekthi yokuhlola amanzi angcolile e-Pearson International Airport e-Toronto ukuze kuhlolwe izinhlobo ze-SARS-CoV-2 kanye ne-mpox emanzini angcolile ezindizeni nasezikhumulweni zezindiza.
UGinkgo usanda kusayina isivumelwano nohulumeni wase-Ukraine, osebone ukwanda kwezifo ezithathelwanayo ngenxa yalolu bhubhane kanye nempi eqhubekayo neRussia, ukusungula iphrojekthi yokuhlola amanzi angcolile ezoqapha i-SARS-CoV-2 kanye nomkhuhlane. Le nkampani futhi isemkhankasweni wokuthuthukisa izinhlelo zokuqapha amanzi angcolile ezindizeni eRwanda naseQatar.
“Kuhle kakhulu ukubona ezinye izindawo zilingisa uhlelo oseluthathe iminyaka emibili yiCDC,” kusho uMcKnight. ‘Uyaqala ukubona lawa amanye amazwe ethi, ‘Ima, leyo yindlela enhle yokwenza.’
‘Kuhlale kunzima ukuba ngowokuqala’
Ukuthola izindiza zase-US nezikhumulo zezindiza ukuthi zivume ukuvumela uhulumeni ukuthi ahlole imfucuza yamakhasimende azo kuzodinga umzamo othile, i-CDC ivume.
“Siyazi ukuthi lokhu kuyasebenza,” kusho uFriedman we-CDC, okhuluma “nabalingani bomhlaba” kanye nezikhumulo zezindiza zase-US lapho uhlelo seluvele luqoqa amakhala mayelana nokuhlolwa kwamanzi angcolile endizeni. Iphrojekthi yokuhlola e-JFK “ibonise ukuthi singakwazi ukubona ukulandelana kwamanzi angcolile,” kusho yena.
Kodwa, wengeza, kuyinselele “ukuthola ukubambisana kuzo zonke izinhlangano ezihlukene… Sisezingxoxweni nezinkampani zezindiza njengamanje kanye nezikhumulo zezindiza ukuze sithole imvume yokuthatha isampula lamanzi angcolile.”
UMcKnight wakwaGinkgo, ophinde akhulume nezinkampani zezindiza mayelana nobuchwepheshe, uthe akukaze kube khona ukusabela okungekuhle okuvela embonini, kodwa abaphathi bezindiza bebeqaphile.
I-Diamond ye-Rockefeller Foundation ithe izindiza ezibamba iqhaza zingabeka engcupheni igama elihle ngoba kungaletha ukugxila eqinisweni lokuthi kunabantu abasendizeni abangenwe yi-Covid, noma ngoba abanye abagibeli bangabona ukuhlaziywa kwemfucuza yabo njengendaba yobumfihlo.
“Kuhlale kunzima ukuba ngowokuqala ukwenza into enobuhle nobubi,” kusho uDiamond.
Uhulumeni kanye nemboni yezindiza kudingeka babeke udaba emphakathini, uthe, ngokuchazela abantu ukuthi ngokuvumela uhulumeni ahlole imfucuza yabo, basiza ukugcina wonke umuntu ephephile.
“Uma senza ukuqapha okuqinile kwamanzi angcolile – emiphakathini noma ezibhedlela noma ezikoleni noma endizeni – akukho ukungabaza emqondweni wami ukuthi sizokuhlomela kakhulu ukubona izinsongo, ukuphendula kuzo ngokushesha futhi sisindise izimpilo eziningi,” kusho yena.
U-Adam Cancryn ufake isandla kulo mbiko.
