Indlela yokumisa i-Omicron ngoku? Inye Kuphela Indlela Eseleyo!

I-Omicron isasazeka njengomlilo wasendle kungekhona e-United States naseYurophu kuphela. Iingcali zilumkisa malunga nokuvalwa okupheleleyo kweziseko ezingundoqo, kunye nengxaki engazange ibonwe umlinganiselo ngenxa yokusasazeka okungalawulekiyo kwe-Omicron variant, eyaziwa ngokuba yi-B.1.1.529.

Inyaniso isandula kutyhilwa:

Uphando lugqitywe nge-31 kaDisemba kwaye lwapapashwa nature.com ichaza oku kulandelayo:

I-Omicron (B.1.1.529) eyahlukileyo ye-acute acute breathing syndrome 2 (SARS-CoV-2) yaqatshelwa ngoNovemba ka-2021 eMzantsi Afrika naseBotswana kunye nesampulu yomhambi osuka eMzantsi Afrika eHong. Kong.

Ukusukela ngoko, i-B.1.1.529 iye yafunyanwa kwihlabathi jikelele.

Lo mahluko ubonakala ngathi wosulela ngokulinganayo kune-B.1.617.2 (i-Delta), sele ibangele iziganeko ze-super spreader, kwaye iye yakhuphisana ne-Delta kwiiveki ezininzi kumazwe nakwiindawo ze-metropolitan.

B.1.1.529 ibamba inani elingazange libonwe ngaphambili leenguqu kwi-spike gene kunye neengxelo zakwangoko zibonelele ngobungqina bokuphunyuka okubanzi kwamajoni omzimba kunye nokuncipha kokusebenza kwesitofu.

Apha, siphande isenzo sokungapheliseki kunye nesibophelelo sesera ukusuka kwi-convalescent, i-mRNA iye yagonywa kabini, i-mRNA yonyuswa, i-convalescent iye yagonywa kabini, kunye ne-convalescent yokomeleza abantu ngokuchasene nohlobo lwasendle, i-B.1.351 kunye ne-B.1.1.529 ye-SARS-CoV-2 yodwa.

Umsebenzi wokungathathi hlangothi wesera osuka kwi-convalescent kunye nabathathi-nxaxheba abagonywe kabini akazange abonwe ukuya phantsi kakhulu ngokuchasene ne-B.1.1.529 ngelixa umsebenzi wokungathathi hlangothi wesera osuka kubantu abaye bachanabeka kwi-spike amaxesha amathathu okanye amane wagcinwa, nangona kumanqanaba ancitshisiweyo kakhulu.

Ukubophelela kwi-B.1.1.529 i-receptor-binding domain (RBD) kunye ne-N-terminal domain (NTD) yancitshiswa kwi-convalescent kungekhona abantu abagonyiweyo kodwa igcinwe kakhulu kubantu abagonyiweyo.

Lo mbhalo-ngqangi uye waphononongwa ngoontanga kwaye wamkelwa ukuba upapashwe kwiNdalo kwaye unikezwe kule fomati apha njengempendulo kwingxaki ekhethekileyo yempilo yoluntu. Lo mbhalo wesandla owamkelweyo uya kuqhubeka ngeenkqubo zokuhlelwa kwekopi kunye nokufometha ukupapashwa kwenguqu egqityiweyo yerekhodi kwi-nature.com.

Nceda uqaphele kunokubakho iimpazamo ezikhoyo kule nguqulo, ezinokuchaphazela umxholo, kwaye zonke izichaso ezisemthethweni ziyasebenza.

Ngokutsho kwenqaku elisanda kukhutshwa okokuqala kwi-CNN International uGqr Peter IsiNgesi, ingcali yokulawula izifo ezosulelayo e-UK, kwingxelo.

Idosi yesithathu yesitofu sokugonya iphucula kakhulu impendulo yesilwa-mntu ngokuchasene nosulelo lwe-Omicron.

Ngokutsho kwe-CNN, uDkt Julian Tang weYunivesithi yaseLeicester, naye owayengabandakanyekanga kwisifundo, naye wathi iimpendulo ze-T-cell zibalulekile ekukhuseleni ixesha elide kwizifo ezinzima. 

"Eyona nto iphambili kukuba ukomeleza ukugonyeka okukhoyo (nokuba isitofu sokugonya okanye sifunyenwe ngokwemvelo) siyanceda ukukhusela kusulelo / ukosuleleka kwakhona kwinqanaba elithile - kunye nokunyusa iimpendulo ezikhoyo ze-T-cell - konke oku kuya kunceda ukusikhusela kwi-Omicron. Ke ukufumana ezi dosi zokukhuthaza kubalulekile- ngakumbi ukuba ukwelinye lamaqela asemngciphekweni,” utshilo uTang
