Ukuqhathaniswa kokuhluka kwe-COVID-19 Omicron kanye ne-Delta Plus

Ekuqaleni kuka-2021, sabona igagasi lesibili le- Ubhubhane lwe-COVID-19 lapho okuhlukile kweDelta Plus kudale uthuthuva. Okuhlukile kwaqala ukutholwa eNdiya futhi kwasakazeka ngokushesha emhlabeni wonke. Lokhu kuhlasela kubone ukulahlekelwa ukuphila okuningana kanye nomthwalo wemfanelo wephula uphawu lwerekhodi. Igagasi lathatha izinyanga ezi-3 kuye kwezi-4, futhi njengoba izinto zibuyela kwesijwayelekile, ukwesaba okuhlukile sekuqalile ukusihlasela. Okuhlukile okungu-B.1.1.529 noma i-Omicron kwaqala ukutholwa eNingizimu Afrika futhi sekumenyezelwe “Okuhlukile Okukhathazayo” yiNhlangano Yezempilo Yomhlaba (WHO). Okuhlukile okusabalala ngokushesha kungadala ukuhlasela kwegagasi lesithathu. Umehluko owodwa omkhulu, noma indawo ekhathazayo, phakathi kwezinhlobo ezi-2 ukuthi i-Omicron inenani elidlulisekayo eliphakeme kunokwehluka kwe-Delta Plus. Ake sibhekisise kabanzi umehluko phakathi kwalezi zihlukaniso ezi-2:

Ukuguqulwa kwamaprotheni e-spike

I-K417N, i-spike protein mutation, itholwe ngokuhlukile kwe-Delta. Lokhu kuholele ekuthuthukisweni kohlobo lweDelta, olugcine lwaziwa ngeleDelta Plus. Iwukuguqulwa okufanayo okwakubuye kwahlotshaniswa nokwahluka kwe-Beta. Ngakolunye uhlangothi, okuhlukile kwe-Omicron kunokuguquguquka okungama-50 okungaphezu kwezingu-32 kumaprotheni e-spike. Ama-protrusions ngaphandle kwegciwane, akhiwe yi-spike protein, asiza igciwane ukuthi lingene kumaseli. Ngakho-ke, ukuguqulwa okuningi kuzoholela ekusakazekeni ngokushesha futhi kubaleke ukuvikela umgomo.

Kunomthelela ekusebenzeni komgomo

Uma kubhekwa inani eliphezulu lezinguquko zokwehluka kwe-Omicron, ososayensi bakhathazekile ngokusebenza komgomo otholakalayo njengamanje. Yize ucwaningo lusaqhubeka, kucatshangelwa ukuthi umgomo wamanje usalindeleke ukuthi uvikele ekuguleni okunzima, ukulaliswa esibhedlela kanye nokufa ngenxa yalokhu kwehluka. Kube nezimo zokutheleleka okuphumelelayo kubantu abathole imithamo emi-2 yemigomo ye-covid. Imithamo ye-booster inconywe ohulumeni abaningi ukulwa nokwehluka okushubile.

Ukulimala

Qhathanisa ukuhluka kwe-COVID-19 Omicron kanye ne-Delta Plus: Okuhlukile kweDelta Plus kudaleke umonakalo ngokwezibalo zabantu abalimala ngenxa yokungakulungeli kweziphathimandla, uhlelo lokunakekelwa kwezempilo oluntekenteke, nokunganaki kwabantu. Ngokuphathelene nokuhluka kwe-Omicron, iziphathimandla bezihlale ziqaphile kusukela zatholwa, futhi izinyathelo ezisebenzayo ziyathathwa ukugwema ukuhlasela okufanayo njengegagasi lesibili. Njengesikhathi sokubhala le bhulogi, i-Australia ibike ukufa kokuqala nokuwukuphela kwe-Omicron emhlabeni.

Amazwe athintekile

Kuze kube manje, okuhlukile kweDelta Plus kubikwe cishe emazweni angama-30, kuyilapho i-Omicron isisabalele emazweni angu-108. Amakhambi okuzigcina uphephile ezintweni ezibulalayo, ezithathelwanayo, nezivela ngokushesha ziyefana- gqoka imaski, zigome futhi ugcine ibanga lomphakathi. Ngaphezu kwalokhu, kufanele usebenzele ukuthuthukisa ukungatheleleki kwakho. Uma kubhekwa ukusabalala okusheshayo kokuhlukile kwe-Omicron, igagasi lesithathu libukeka lingenakugwenywa, kodwa kukithi ukuthi singazigcina kanjani siphephile. Esinye sezizathu ezinkulu ezenze igagasi lesibili lodlame kwakuwukungazi kwabantu, futhi okufanayo ngalezi zikhathi ezibucayi kungaholela kumphumela ofanayo. Ngakho-ke, phepha ngokuzitholela umgomo futhi ulandele yonke imikhuba ye-COVID-19.
