I-EG.5 isasazeka ngokukhawuleza, kodwa iingcali zithi ayikho ingozi kuneenguqulelo zangaphambili.Olunye uhlobo olutsha, olubizwa ngokuba yi-BA.2.86, lubekwe iliso elibukhali ukuze kuguqulwe iinguqu.
Kukho iinkxalabo ezikhulayo malunga ne-Covid-19 eyahlukileyo EG.5 kunye ne-BA.2.86.Ngo-Agasti, i-EG.5 yaba yinto ehluke kakhulu e-United States, kunye noMbutho wezeMpilo weHlabathi uchaza "njengentlupheko yomdla," oku kuthetha ukuba unokuguqulwa kofuzo olunika inzuzo, kwaye ukuxhaphaka kwayo kuyanda.
I-BA.2.86 ayiqhelekanga kakhulu kwaye ithatha iqhezu kuphela leemeko, kodwa izazinzulu ziye zothuswa ngamanani eenguqu eziziphetheyo.Ngoko abantu kufuneka bakhathazeke kangakanani ngezi ndlela?
Ngelixa isigulo esiqatha phakathi kwabantu abadala kunye nabo baneemeko zonyango ezisezantsi kusoloko kuyinkxalabo, njengoko injalo imeko yexesha elide yakhe nawuphi na umntu owosulelekileyo nge-COVID-19, iingcali zithi i-EG.5 ayibeki soyikiso sibalulekileyo, okanye hayi.Ukhetho oluphambili olukhoyo ngoku luza kubangela isoyikiso esikhulu kunayo nayiphi na enye.
U-Andrew Pekosh, unjingalwazi we-molecular microbiology kunye ne-immunology kwiYunivesithi yaseJohns Hopkins, uthe: "Kukho inkxalabo yokuba le ntsholongwane iyanda, kodwa ayifani nentsholongwane ebijikeleza e-United States kwezi nyanga zintathu ukuya kwezine zidlulileyo."… Ayohlukanga kangako.”IYunivesithi yaseBloomberg yeSikolo seMpilo yoLuntu."Ke ndicinga ukuba yiyo loo nto ndinexhala ngolu khetho ngoku."
Nditsho noMbutho wezeMpilo weHlabathi uthe kwingxelo esekelwe kwidatha ekhoyo, "umngcipheko wezempilo woluntu owenziwe yi-EG.5 uqikelelwa ukuba uphantsi kwihlabathi jikelele."
Umahluko wafunyanwa e-China ngoFebruwari ka-2023 kwaye waqala ukubonwa e-US ngo-Epreli.Yinzala yokwahluka kwe-Omicron's XBB.1.9.2 kwaye inoguquko oluphawulekayo oluyincedayo ukubaleka izilwa-buhlungu zesixokelelwano sokhuselo lomzimba ngokuchasene nokwahluka kwangaphambili kunye nezitofu zokugonya.Olu lawulo lunokuba kutheni i-EG.5 ibe lolona xinzelelo lubalaseleyo kwihlabathi jikelele, kwaye inokuba sesinye sezizathu zokuba kutheni iimeko zesithsaba ezitsha zinyuka kwakhona.
Uguquko "lunokuthetha ukuba abantu abaninzi banokuchaphazeleka kuba intsholongwane inokuphepha ukungakhuseleki ngakumbi," utshilo uGqr. Pecos.
Kodwa i-EG.5 (eyaziwa ngokuba ngu-Eris) ayibonakali inamandla amatsha ngokumalunga nokusuleleka, iimpawu, okanye ukukwazi ukubangela isifo esibi.Ngokutsho kukaGqr Pekosh, iimvavanyo zokuxilonga kunye nonyango olufana ne-Paxlovid lusasebenza.
UGqr. Eric Topol, usekela-mongameli olawulayo weZiko loPhando lweScripps eLa Jolla, eCalif., Uthe akazange akhathazeke ngokugqithiseleyo ngolu khetho.Nangona kunjalo, angaziva ngcono ukuba ifomula entsha yesitofu sokugonya, ekulindeleke ukuba ikhutshwe ekwindla, sele ikwimarike.I-booster ehlaziyiweyo yaphuhliswa ngokusekelwe kwintlukwano eyahlukileyo efana ne-EG.5 gene.Kulindeleke ukuba ibonelele ngokhuseleko olungcono ngokuchasene ne-EG.5 kunesitofu sokugonya sonyaka ophelileyo, esijolise kuhlobo lokuqala lwe-coronavirus kunye ne-Omicron yangaphambili, eyayinxulumene kuphela kude.
"Inkxalabo yam enkulu ngabantu abasengozini enkulu," utshilo uGqr Topol.“Isitofu sokugonya abasifumanayo sikude lee apho intsholongwane ikhoyo nalapho iya khona.”
Olunye uhlobo olutsha olujongwe ngoosonzululwazi yiBA.2.86, ebizwa ngokuba yiPirola.I-BA.2.86, ephuma kolunye uhlobo lwe-Omicron, iye yadityaniswa ngokucacileyo neemeko ezingama-29 zekoronavirus entsha kumazwekazi amane, kodwa iingcali zikrokrela ukuba inosasazo olubanzi.
Izazinzulu zinike ingqwalasela eyodwa kolu tshintsho ngenxa yenani elikhulu lotshintsho oluthwalayo.Uninzi lwezi zifumaneka kwiprotein ye-spike esetyenziswa ziintsholongwane ukosulela iiseli zabantu kwaye amajoni ethu omzimba asebenzisa ukuqaphela iintsholongwane.UJesse Bloom, unjingalwazi kwiZiko loMhlaza likaFred Hutchinson ogxile ekuziphendukeleni kwentsholongwane egazini, uthe uguquko lwe-BA.2.86 lubonisa "ukutsiba kwemvelo okulinganayo" ukusuka kuhlobo lokuqala lwe-coronavirus xa kuthelekiswa notshintsho kwi-Omicron yokuqala.
Idatha epapashwe kule veki ngoososayensi baseTshayina kwisayithi ye-X (eyayibizwa ngokuba yi-Twitter) ibonise ukuba i-BA.2.86 yahluke kakhulu kwiinguqulelo zangaphambili zentsholongwane kangangokuba iphephe ngokulula izilwa-buhlungu ezenziwe ngokuchasene nosulelo lwangaphambili, nangaphezulu kune-EG.5. ukubaleka.Ubungqina (obungekapapashwa okanye buphononongwe ngoontanga) bucebisa ukuba izitofu zokugonya ezihlaziyiweyo nazo aziyi kusebenza kangako kulo mba.
Ngaphambi kokuba uphelelwe lithemba, uphando lukwabonisa ukuba i-BA.2.86 ingosuleli kakhulu kunezinye iindidi, nangona uphononongo kwiiseli zelebhu alusoloko luhambelana nendlela intsholongwane eziphatha ngayo kwihlabathi lokwenyani.
Ngosuku olulandelayo, izazinzulu zaseSweden zapapasha kwiqonga X iziphumo ezikhuthazayo (nazo ezingapapashwanga nezingabonwanga) ezibonisa ukuba izilwa-buhlungu eziveliswa ngabantu abasanda kusulelwa yi-Covid zibonelela ngokhuseleko kwi-BA.2.86 xa zivavanywa elebhu.ukhuselo.Iziphumo zabo zibonisa ukuba izilwa-buhlungu eziveliswe sisitofu esitsha sokugonya aziyi kuba namandla ngokupheleleyo ngokuchasene nalo mahluko.
"Enye imeko enokwenzeka kukuba i-BA.2.86 ayisuleli kakhulu kuneenguqu zangoku kwaye ngoko ayiyi kusasazwa ngokubanzi," uGqr Bloom wabhala kwi-imeyile kwiNew York Times."Nangona kunjalo, kuyenzeka ukuba lo mahluko usasazeke ngokubanzi - kuya kufuneka silinde idatha engaphezulu ukuze sifumane."
