I-Deltacron ayilohlobo olutsha okanye uhlobo olutsha kodwa yimeko yosulelo kunye neentlobo ezimbini ze-SARS-CoV-2. Kule minyaka mibini idlulileyo, kuye kwavela ukwahluka okwahlukileyo kohlobo lwe-SARS CoV-2 olunenqanaba elahlukileyo lokosulela kunye nobunzima besifo. Izahluko ezinje nge-delta kunye ne-omicron ziqala ukubangela ukuhlangana, okukhokelela kwiingxelo zemithombo yeendaba zibhala njengeentlobo ezahlukeneyo zentsholongwane. Nangona kunjalo, oku kuyalahlekisa njengoko kulusulelo olubangelwa kukudityaniswa kwezinto ezimbini ezahlukeneyo, utsho uRajeev Soni, iNgcali yeBhayoloji yeMolekyuli kunye neBiotechnologist.
Ubhubhani we-COVID-19 obangelwe yi-SARS CoV-2 uhlobo lwentsholongwane ye-corona uye waqhwalelisa umhlaba wonke kule minyaka mibini idlulileyo, ucutha uqoqosho kwaye umisa ubomi obuqhelekileyo. Njengoko intsholongwane isosulela abantu abaninzi, iintlobo ezintsha ziyavela1 ngenxa yotshintsho kwikhowudi yemfuza. Ukwahluka okutsha kwimeko ye-SARS-CoV-2 yoxinzelelo lwentsholongwane luyavela ngenxa yotshintsho, ngokuyintloko kwi-receptor binding domain (RBD) ye-spike protein. Ukongeza, ukucinywa kwemimandla ngaphakathi kweeproteni ze-spike kuye kwaxelwa. Eyona nto imbi kakhulu iye yahluka kwi-delta ebangele ukonyuka kosulelo lwe-COVID kwihlabathi liphela, kunye nokunyuka kokusweleka kwabantu. Kutshanje, ngoNovemba ka-2021, uMzantsi Afrika unike ingxelo yolunye uhlobo olubizwa ngokuba yi-Omicron, eyosulela ngokuphindwe ka-4 ukuya kwi-6 kunokwahluka kwe-delta, nangona ibangela isifo esincinci. Olunye uhlobo olubizwa ngokuba yi-IHU eyahlukileyo2 ichongiwe eFrance kwezi veki zimbini zidlulileyo.
Ukongeza, kukho ingxelo yosulelo oludibeneyo lwabantu abahlukeneyo hlu kileyo, umz. idelta kunye ne-omicron. Nokuba silubiza usulelo yiDelmicron okanye iDeltacron, into ebalulekileyo ekufuneka uyikhumbule kukuba la magama abhekisa kusulelo olubangelwa kukudibana “kweendlela ezimbini ezahlukeneyo zentsholongwane. ubunzima obufanayo yentsholongwane, i-SARS CoV-2 ″, kwaye ingabhidaniswa "njengeentlobo" ezahlukeneyo, utshilo uGqr. Rajeev Soni, i-Molecular Biologist kunye ne-Biotechnologist, kunye nomfundi weYunivesithi yaseCambridge, e-UK.
Ukubiza i-coinfection ngeendlela ezahlukeneyo, uhlobo olwahlukileyo lwentsholongwane luyalahlekisa. Uxinzelelo luqhele ukubhekiswa kulo njengokwahluka kakhulu ngokweempawu zebhayoloji kunye nokuziphatha, nto leyo ngokuqinisekileyo ayinjalo ngokwahluka okubonwayo ukuza kuthi ga ngoku.3. Olunye usulelo ekuye kwaxelwa ngalo lelo linentsholongwane yomkhuhlane kunye nohlobo lwentsholongwane ye-corona oluthiya usulelo njenge-Flurona. Loo nto ayimenzi uFlurona uhlobo olwahlukileyo kwaphela.
Kwiintsuku ezizayo, iintlobo ezininzi ziya kuvela ezinokuthi zikhokelele kwii-coinfections ezininzi. Nangona kunjalo, ezi akufuneki zibizwe njengeentlobo ezahlukeneyo zentsholongwane. I-nomenclature kufuneka iphelele kuphela kwisifo esibangelwa usulelo lweentlobo ezibandakanyekayo.
