Ukusuka ngaphezulu kwama-200 amatyala amatsha aqinisekisiweyo ngosuku kwiiveki nje ezidlulileyo, uMzantsi Afrika ubone inani lamatyala amatsha emihla ngemihla ukuya ngaphezulu kwe-3,200 ngoMgqibelo, uninzi lwaseGauteng.
Ukuzabalaza ukucacisa ukunyuka kwamatyala ngequbuliso, izazinzulu zafunda iisampulu zentsholongwane kwaye zafumanisa uhlobo olutsha.Ngoku, malunga ne-90% yamatyala amatsha eGauteng abangelwa yiyo, ngokutsho kukaTulio de Oliveira, umlawuli weKwaZulu-Natal Research Innovation and Sequencing Platform.

KUTHENI Izazinzulu ZIKHATHAZEKILE NGALE NTSHA YAHLUKENEYO?
Emva kokubiza iqela leengcali ukuvavanya idatha, i-WHO yathi "ubungqina bokuqala bucebisa ukonyuka komngcipheko wokosuleleka kwakhona ngolu hlobo," xa kuthelekiswa nezinye izinto ezahlukeneyo.
Oko kuthetha ukuba abantu abosulelwe yi-COVID-19 kwaye baphola banokuphinda bayibambe.
Umahluko ubonakala unenani eliphezulu lotshintsho- malunga nama-30 - kwiprotein ye-coronavirus' spike, enokuthi ichaphazele indlela esasazeka ngayo ebantwini.
USharon Peacock, okhokele ulandelelwano lwemfuza ye-COVID-19 eBhritane kwiYunivesithi yaseCambridge, uthe idatha ukuza kuthi ga ngoku icebisa ukuba umahluko omtsha unoguquko “oluhambelana nokugqithisela okuguquguqukayo,” kodwa wathi "ukubaluleka kotshintsho oluninzi lutshintsho. nangoku ayaziwa.”
ULawrence Young, isazi ngentsholongwane kwiYunivesithi yaseWarwick, uchaze i-omicron “njengeyona nguqulelo iguquguqukayo yentsholongwane esiyibonileyo,” kubandakanya neenguqu ezinokuba nexhala ezingazange zibonwe zonke kwintsholongwane enye.

YINTONI EKWAZIWAYO NENGAZIWAYO NGENXA YOLUHLUKO?
Izazinzulu ziyazi ukuba i-omicron yohlukile ngokwemfuza kwiintlobo zangaphambili eziquka i-beta kunye ne-delta eyahlukileyo, kodwa abazi ukuba olu tshintsho lwemfuza luyenza ukuba yosuleleke ngakumbi okanye ibe yingozi.Ukuza kuthi ga ngoku, akukho nto ibonisa ukuba lo mahluko ubangela isifo esiqatha.
Kuya kuthatha iiveki ukulungisa ukuba i-omicron yosulela ngakumbi kwaye ukuba izitofu zokugonya zisasebenza ngokuchasene nayo.
UPeter Openshaw, unjingalwazi weyeza lovavanyo kwiKholeji yase-Imperial yaseLondon uthe "ayinakwenzeka kakhulu" into yokuba izitofu zokugonya zingasebenzi, eqaphela ukuba ziyasebenza ngokuchasene nezinye izinto ezininzi.
Nangona ezinye iinguqu zofuzo kwi-omicron zibonakala zixhalabile, akukacaci ukuba ziyakwenza ingozi kwimpilo yoluntu.Ezinye iinguqulelo zangaphambili, njengokwahluka kwe-beta, zaqala zothusa izazinzulu kodwa aziphelanga zisasazeka kude kakhulu.
“Asazi ukuba lo mahluko mtsha unokufikelela kwindawo apho i-delta ikhona,” utshilo uPeacock weYunivesithi yaseCambridge."Ijaji isazi ukuba lo mahluko uzakwenza njani apho kukho ezinye izinto ezijikelezayo."
Ukuza kuthi ga ngoku, i-delta yeyona ndlela ibalaseleyo ye-COVID-19, ibala ngaphezulu kwe-99% yolandelelwano olungeniswe kwindawo enkulu yedatha yoluntu yehlabathi.

KWAVUKA NJANI LE NDLELA ENTSHA?
I-coronavirus iyatshintsha njengoko isasazeka kwaye uninzi lwezinto ezintsha, kubandakanya nezo zinexhala lotshintsho lwemfuza, zihlala ziphela.Izazinzulu zibeke iliso kulandelelwano lwe-COVID-19 kutshintsho olunokwenza ukuba isifo sosuleleke ngakumbi okanye sibulale, kodwa abanakumisela oko ngokujonga nje intsholongwane.
U-Peacock uthe umahluko "unokuba uvela kumntu owosulelekileyo kodwa akakwazi ukuyisusa intsholongwane, enika intsholongwane ithuba lokuvela ngokwemfuza," kwimeko efana nendlela iingcali ezicinga ngayo ukwahluka kwe-alpha - eyaqala ukuchongwa eNgilani - kwavela kwakhona, ngokuguqula kwi-immune-compromised.
INGABA IZITHINTELO ZOKUHAMBA IBEKWA NGAMANYE AMAZWE IYATHETHELWA?
Ingayiyo.
U-Israyeli unqanda abantu basemzini ukuba bangene kwidolophu kwaye iMorocco iyekile konke ukuhamba ngenqwelomoya okungenayo.
Iqela lamanye amazwe anqanda iinqwelomoya ezisuka kumazantsi eAfrika.
Ngenxa yokunyuka okukhawulezileyo kwe-COVID-19 eMzantsi Afrika, ukuthintela ukuhamba ukusuka kulo mmandla “bubulumko” kwaye kuya kuthenga abasemagunyeni ixesha elingakumbi, utshilo uNeil Ferguson, ingcali yezifo ezosulelayo kwiKholeji yase-Imperial yaseLondon.
Kodwa i-WHO yaphawula ukuba izithintelo ezinjalo zihlala zilinganiselwe kwimpembelelo yazo kwaye yabongoza amazwe ukuba agcine imida ivulekile.
UJeffrey Barrett, umlawuli we-COVID-19 Genetics kwi-Wellcome Sanger Institute, wacinga ukuba ukubonwa kwangoko kolu tshintsho lutsha kunokuthetha ukuba izithintelo ezithathiweyo ngoku zinokuba nefuthe elikhulu kunaxa kwavela ukwahluka kwedelta kuqala.
"Nge-delta, kuthathe iiveki ezininzi kwi-India eyoyikisayo ngaphambi kokuba kucace ukuba kuqhubeka ntoni kwaye i-delta yayisele izityala kwiindawo ezininzi emhlabeni kwaye kwakusele kusemva kwexesha ukuba yenze nantoni na ngayo," utshilo."Sisenokuba sikwindawo yangaphambili ngalo mahluko mtsha ke kusenokubakho ixesha lokwenza okuthile ngalo."
Urhulumente waseMzantsi Afrika uthe ilizwe liphathwa ngokungekho sikweni kuba lihambele phambili ngokulandelelana kwe-genomic kwaye linokubona umahluko ngokukhawuleza kwaye wacela amanye amazwe ukuba aphinde athathele ingqalelo ukuvalwa kokuhamba.
