Ukwahluka okutsha kunye nokosulelayo kunye nobungozi be-Omicron, okwangoku ebizwa ngokuba yi-Omicron BA.2 subtype variant, kuye kwavela nokuba kubalulekile kodwa kuxoxwe kancinane kunemeko yase-Ukraine. (Inqaku lomhleli: Ngokutsho kwe-WHO, i-Omicron strain ibandakanya i-b.1.1.529 spectrum kunye nenzala yayo i-ba.1, i-ba.1.1, i-ba.2 kunye ne-ba.3. ba.1 isabala uninzi lwezifo, kodwa ba.2 usulelo luyanda.)
I-BUPA ikholelwa ukuba ukuguquguquka okuqhubekayo kwiimarike zamazwe ngamazwe kwezi ntsuku zimbalwa zidlulileyo kungenxa yokuwohloka kwemeko e-Ukraine, kwaye esinye isizathu luhlobo olutsha lwe-Omicron, uhlobo olutsha lwentsholongwane ekholelwa ukuba i-arhente ikhula emngciphekweni kwaye impembelelo enkulu kuqoqosho lwehlabathi inokuba ibaluleke ngakumbi kunemeko yaseUkraine.
Ngokweziphumo zamva nje ezifunyenwe kwiDyunivesithi yaseTokyo eJapan, i-BA.2 subtype eyahlukileyo ayisasazeki ngokukhawuleza xa ithelekiswa ne-COVID-19 ekhoyo ngoku, i-Omicron BA.1, kodwa inokubangela ukugula kakhulu kwaye ibonakala ngathi iyakwazi ukuthintela. ezinye zezixhobo eziphambili esinazo ngokuchasene ne-COVID-19.
Abaphandi bosulela i-hamster nge-BA.2 kunye ne-BA.1 strains, ngokulandelanayo, kwaye bafumanisa ukuba abo banesifo se-BA.2 babegula kakhulu kwaye babenomonakalo omkhulu wemiphunga. Abaphandi bafumanise ukuba i-BA.2 isenokuthi ithintele ezinye zezilwa-buhlungu eziveliswa sisitofu sokugonya kwaye iyaxhathisa kumachiza athile onyango.
Abaphandi bolingelo bathi, "Uvavanyo lokungathathi hlangothi lucebisa ukuba ugonyo olubangelwa kukugonya alusebenzi kakuhle ngokuchasene ne-BA.2 njengoko lwenza ngokuchasene ne-BA.1."
Iimeko ze-BA.2 ezahlukeneyo zentsholongwane ziye zaxelwa kumazwe amaninzi, kwaye i-World Health Organization iqikelela ukuba i-BA.2 imalunga neepesenti ezingama-30 ezosulelayo kune-BA.1 yangoku, efunyenwe kumazwe angama-74 kunye ne-47 yase-US.
Le ntsholongwane ithatha i-90% yazo zonke iimeko ezintsha eDenmark. IDenmark ibone ukuphindaphindwa kwamva nje kwinani lamatyala asweleke ngenxa yosulelo lwe-COVID-19.
Iziphumo ezivela kwiYunivesithi yaseTokyo eJapan kunye nento eyenzekayo eDenmark ziye zalumkisa ezinye iingcali zamazwe ngamazwe.
I-Epidemiologist uDkt Eric Feigl-Ding wathatha kwi-Twitter ukubiza imfuno ye-WHO (i-World Health Organization) ukuvakalisa ukuhluka okutsha kwe-Omicron BA.2 isizathu sokukhathazeka.
UMaria Van Kerkhove, ukhokelo lwezobuchwepheshe lwe-WHO kwi-coronavirus entsha, kwakhona wathi i-BA.2 sele iyinto entsha ye-Omicron.
Abaphandi bathi.
"Nangona i-BA.2 ithathwa njengento entsha ye-mutant ye-Omicron, ukulandelelana kwayo kwe-genome kuhluke kakhulu kwi-BA.1, ebonisa ukuba i-BA.2 ineprofayili ye-virological eyahlukileyo kune-BA.1."
I-BA.1 kunye ne-BA.2 ineziguquko ezininzi, ngokukodwa kwiindawo eziphambili zeprotheni ye-viral stinger. UJeremy Luban, ugqirha we-virologist kwiYunivesithi yaseMassachusetts Medical School, uthe i-BA.2 ineqela elipheleleyo leenguqu ezintsha ekungekho mntu uye wavavanya.
UMads Albertsen, isazi sebhayoloji kwiYunivesithi yase-Aalborg eDenmark, uthe ukwanda ngokuthe ngcembe kwe-BA.2 kumazwe aliqela kubonisa ukuba inenzuzo yokukhula ngaphezu kwezinye izinto ezahlukeneyo, kuquka nezinye ii-subtype ezahlukeneyo ze-Omicron, ezifana ne-spectrum engaziwayo kakhulu eyaziwa ngokuba yi-BA. 3.
Uphononongo olwenziwa kwiintsapho ezingaphezu kwama-8,000 zaseDenmark ezosulelwe yiomicron lubonisa ukuba umlinganiselo owandileyo we-BA.2 usulelo ngenxa yezinto ezahlukahlukeneyo. Abaphandi, kuqukwa uTroels Lillebaek, ugqirha wezifo zezifo kunye nosihlalo weDanish Committee for Risk Assessment of COVID-19 Variants, bafumanise ukuba abantu abangagonywanga, abagonywe kabini kunye nabagonywe nge-booster-booster babonakele ngakumbi ukuba bosulelwe yi-BA.2 kune-BA.1 usulelo.
Kodwa uLillebaek uthe i-BA.2 inokubangela umngeni omkhulu apho amazinga okugonya aphantsi. Inzuzo yokukhula yale ntlukwano ngaphezu kwe-BA.1 ithetha ukuba inokwandisa incopho yosulelo lwe-omicron, ngokwandisa amathuba okusuleleka kubantu abadala kunye nabanye abantu abasengozini enkulu yesifo esibi.
Kodwa kukho indawo eqaqambileyo: izilwa-buhlungu ezisegazini labantu abasandul’ ukosulelwa yintsholongwane ye-omicron nazo zibonakala zibonelela ngokhuseleko oluthile kwi-BA.2, ngakumbi ukuba nazo ziye zagonywa.
Oku kuphakamisa inqaku elibalulekileyo, utsho kwiYunivesithi yaseWashington School of Medicine ugqirha wentsholongwane kaGawulayo u-Deborah Fuller, ukuba ngelixa i-BA.2 ibonakala ngathi iyosulela kwaye i-pathogenic kune-Omicron, inokungapheleli ibangela igagasi elitshabalalisayo losulelo lwe-COVID-19.
Intsholongwane ibalulekile, utshilo, kodwa kunjalo nathi njengabamkeli bayo abanokubakho. Sisekugqatso oluchasene nentsholongwane, kwaye ayiloxesha lokuba uluntu luphakamise umthetho wemaski.
