I-EG.5 isakazeka ngokushesha, kodwa ochwepheshe bathi ayiyona ingozi kunezinguqulo zangaphambilini.Okunye okuhlukile okusha, okubizwa nge-BA.2.86, kwaqashwa ngeso elibukhali ukuze kutholakale ukuguqulwa kwezakhi zofuzo.
Kunokukhathazeka okukhulayo mayelana nezinhlobonhlobo ze-Covid-19 EG.5 kanye ne-BA.2.86.Ngo-Agasti, i-EG.5 yaba ukuhluka okuvelele e-United States, neNhlangano Yezempilo Yomhlaba ikubeka kusigaba "njengokuhlukile kwentshisakalo," okusho ukuthi inoshintsho lofuzo olunikeza inzuzo, futhi ukusabalala kwayo kuyanda.
I-BA.2.86 ayivamile neze futhi ilandisa ingxenye encane kuphela yamacala, kodwa ososayensi baye bashaqeka ngenani lezinguquko ezithwalayo.Ngakho-ke kufanele abantu bakhathazeke kangakanani ngalezi zinketho?
Yize ukugula okunzima phakathi kwabantu asebekhulile nalabo abanezimo zempilo ezingaphansi kuhlale kukhathaza, njengoba kuyisimo sesikhathi eside sanoma yimuphi umuntu onegciwane le-COVID-19, ochwepheshe bathi i-EG.5 ayibangeli usongo olukhulu, noma okungenani akunjalo.Inketho eyinhloko ebusayo njengamanje izodala usongo olukhulu kunanoma iyiphi enye.
U-Andrew Pekosh, uprofesa we-molecular microbiology and immunology eJohns Hopkins University, uthe: “Kunokukhathazeka ngokuthi leli gciwane liyakhula, kodwa akufani naleli gciwane ebelizungeza e-United States ezinyangeni ezintathu kuya kwezine ezedlule.”… Akuhlukile kangako.”I-Bloomberg University School of Public Health.Ngakho-ke ngicabanga ukuthi yingakho ngikhathazekile ngale nketho njengamanje.
Ngisho neNhlangano Yezempilo Yomhlaba esitatimendeni yathi ngokusekelwe kudatha etholakalayo, "ingozi yezempilo yomphakathi ebangelwa i-EG.5 ilinganiselwa ukuthi iphansi emhlabeni jikelele."
Okuhlukile kwatholwa e-China ngoFebhuwari 2023 futhi kwaqala ukutholwa e-US ngo-Ephreli.Iyinzalo yokwahluka kwe-Omicron's XBB.1.9.2 futhi inoguquko oluphawulekayo olusiza ukuba igweme amasosha omzimba ngokumelene nezinhlobonhlobo zangaphambili nemithi yokugoma.Lokhu kubusa kungase kube yisizathu esenza ukuthi i-EG.5 ibe uhlobo oluvelele emhlabeni wonke, futhi kungase kube esinye sezizathu zokuthi kungani amacala amasha akhuphuka futhi.
Ukuguqulwa kwezakhi zofuzo "kungase kusho ukuthi abantu abaningi bazongenwa kalula ngoba leli gciwane lingagwema ukuzivikela okwengeziwe," kusho uDkt. Pecos.
Kodwa i-EG.5 (eyaziwa nangokuthi i-Eris) ayibonakali inamandla amasha mayelana nokutheleleka, izimpawu, noma amandla okubangela isifo esibi.NgokukaDkt. Pekosh, ukuhlolwa kokuxilonga nokwelashwa okufana ne-Paxlovid kusasebenza.
UDkt. Eric Topol, iphini likamongameli omkhulu weScripps Research Center eLa Jolla, Calif., uthe akakhathazekile ngokweqile ngale ndlela.Kodwa-ke, ubengazizwa engcono uma ifomula entsha yokugoma, okulindeleke ukuthi ikhishwe ekwindla, isivele isemakethe.I-booster ebuyekeziwe yathuthukiswa ngokusekelwe kokuhlukile okuhlukile okufana nofuzo lwe-EG.5.Kulindeleke ukuthi inikeze isivikelo esingcono ku-EG.5 kunomuthi wokugoma wangonyaka odlule, owawuqondise uhlobo lokuqala lwe-coronavirus kanye ne-Omicron yangaphambili, eyayihlobene kude kuphela.
“Okungikhathaza kakhulu abantu abasengozini enkulu,” kusho uDkt. Topol.“Umuthi wokugoma abawutholayo uqhelelene nalapho igciwane likhona nalapho liya khona.”
Olunye uhlobo olusha ososayensi abalubhekisise kakhulu i-BA.2.86, ebizwa ngokuthi i-Pirola.I-BA.2.86, esuselwe kolunye uhlobo lwe-Omicron, iye yahlotshaniswa ngokusobala nezigameko ezingu-29 ze-coronavirus entsha kuwo wonke amazwekazi amane, kodwa ochwepheshe basola ukuthi inokusabalalisa okubanzi.
Ososayensi bakunake lokhu okuhlukile ngenxa yenani elikhulu lokuguqulwa okukuphethe.Eziningi zalezi zitholakala kuphrotheni eyi-spike esetshenziswa amagciwane ukuthelela amangqamuzana omuntu futhi amasosha ethu omzimba ayisebenzisayo ukubona amagciwane.U-Jesse Bloom, uprofesa e-Fred Hutchinson Cancer Centre ogxile ekuziphendukeleni kwegciwane, uthe ukuguqulwa kwe-BA.2.86 kumele "ukukhuphuka kokuziphendukela kwemvelo okulingana nobukhulu obufanayo" obusuka kuhlobo lokuqala lwe-coronavirus uma kuqhathaniswa noshintsho ekuhlukeni kokuqala kuka-Omicron.
Idatha eshicilelwe kuleli sonto ososayensi baseShayina endaweni ye-X (eyaziwa ngokuthi i-Twitter) ibonise ukuthi i-BA.2.86 yayihluke kakhulu ezinguqulweni zangaphambili zegciwane kangangokuthi yayigwema kalula amasosha omzimba enziwe ngokumelene nezifo zangaphambili, ngisho nangaphezulu kune-EG.5. ukuphunyuka.Ubufakazi (obungakashicilelwa noma obubuyekezwe ontanga) buphakamisa ukuthi imithi yokugoma ebuyekeziwe ngeke isebenze kahle kulokhu.
Ngaphambi kokuthi uphelelwe ithemba, ucwaningo luphinde lubonise ukuthi i-BA.2.86 ingase ingatheleleki kancane kunezinye izinhlobo, nakuba izifundo kumaseli elebhu zingahlali zihambisana nendlela igciwane eliziphatha ngayo emhlabeni wangempela.
Ngosuku olulandelayo, ososayensi baseSweden banyathelisa endaweni yesikhulumi X imiphumela ekhuthazayo eyengeziwe (nayo engashicilelwe futhi engahloliwe) ebonisa ukuthi amasosha omzimba akhiqizwa abantu abasanda kutheleleka nge-Covid ayanikeza ukuvikeleka okuthile ku-BA.2.86 lapho ehlolwa elebhu.isivikelo.Imiphumela yabo ikhombisa ukuthi amasosha omzimba akhiqizwe umgomo omusha ngeke abe namandla ngokuphelele ngokumelene nalokhu okuhlukile.
"Isimo esisodwa esingenzeka ukuthi i-BA.2.86 ayitheleleki kangako kunezinhlobonhlobo zamanje ngakho-ke ngeke isatshalaliswe kabanzi," uDkt. Bloom wabhala ku-imeyili eya ku-New York Times."Kodwa-ke, kungenzeka futhi ukuthi lokhu okuhlukile kusabalele - kuzodingeka silinde imininingwane eyengeziwe ukuze sithole."
