Omicron ikufalikira ngati moto wolusa osati ku United States ndi ku Ulaya kokha. Akatswiri amachenjeza za kutsekedwa kwathunthu kwa zomangamanga zovuta, ndi vuto lomwe silinakumanepo chifukwa cha kufalikira kosalamulirika kwa mtundu wa Omicron, womwe umatchedwanso B.1.1.529.
Choonadi changowulula:
Kafukufuku wangomaliza pa Disembala 31 ndikusindikizidwa nature.com akuti:
Mtundu wa Omicron (B.1.1.529) wa acute acute kupuma kwa coronavirus 2 (SARS-CoV-2) udadziwika koyamba mu Novembala 2021 ku South Africa ndi Botswana komanso chitsanzo cha munthu wina wapaulendo wochokera ku South Africa ku Hong. Kongo.
Kuyambira pamenepo, B.1.1.529 yadziwika padziko lonse lapansi.
Kusiyanaku kukuwoneka kuti ndi kachilombo kofanana ndi B.1.617.2 (Delta), kwayambitsa kale zochitika zofalitsa kwambiri, ndipo kwapambana Delta mkati mwa milungu ingapo m'maiko angapo ndi mizinda yayikulu.
B.1.1.529 imakhala ndi masinthidwe ochuluka kuposa kale lonse mu jini yake yowonjezereka ndipo malipoti oyambirira apereka umboni wa kuthawa kwakukulu kwa chitetezo cha mthupi komanso kuchepa kwa mphamvu ya katemera.
Apa, tidafufuza ntchito yoletsa kuletsa komanso yomangirira ya sera kuchokera ku kuchira, katemera wa mRNA woperekedwa kawiri, wowonjezera mRNA, katemera wa convalescent kawiri, komanso kulimbikitsa anthu kumenyana ndi mitundu yakuthengo, B.1.351 ndi B.1.1.529 SARS-CoV-2 kudzipatula.
Zochita zosokoneza za sera kuchokera kwa omwe adalandira katemera komanso omwe adalandira katemera kawiri sizinadziwike mpaka zotsika kwambiri polimbana ndi B.1.1.529 pomwe ntchito zochepetsera za sera kuchokera kwa anthu omwe adakumana ndi spike katatu kapena kanayi zidasungidwa, ngakhale zidachepetsedwa kwambiri.
Kumanga ku B.1.1.529 receptor-binding domain (RBD) ndi N-terminal domain (NTD) kunachepetsedwa mu convalescent osati anthu olandira katemera koma makamaka anasungidwa mwa anthu otemera.
Zolemba pamanjazi zawunikidwanso ndi anzawo ndikuvomerezedwa kuti zifalitsidwe mu Chilengedwe ndipo zaperekedwa mwanjira iyi pano ngati yankho ku vuto lapadera laumoyo wa anthu. Zolemba zovomerezekazi zipitilira munjira zokopera ndikusintha mpaka kusindikizidwa kwa mbiri yomaliza pa nature.com.
Chonde dziwani kuti pakhoza kukhala zolakwika mumtunduwu, zomwe zingakhudze zomwe zili, ndipo zokanira zonse zamalamulo zikugwira ntchito.
Malinga ndi nkhani yomwe yangotulutsidwa kumene pa CNN International Dr. Peter English, katswiri wa matenda opatsirana ku UK, adatero m'mawu ake.
Mlingo wachitatu wa katemera umathandizira kwambiri kuyankha kwa antibody motsutsana ndi matenda a Omicron.
Malingana ndi CNN, Dr. Julian Tang wa yunivesite ya Leicester, yemwenso sanachite nawo phunziroli, adanenanso kuti mayankho a T-cell ndi ofunikira kuti atetezedwe kwa nthawi yaitali ku matenda aakulu.
"Chofunikira ndichakuti kulimbikitsa chitetezo chamthupi chomwe chilipo (kaya katemera kapena wopezedwa mwachilengedwe) kumathandizira kuteteza ku matenda / kuyambukiridwanso pamlingo wina - komanso kulimbikitsa mayankho omwe alipo a T-cell - zonse zomwe zingathandize kutiteteza ku Omicron. Chifukwa chake kupeza milingo yolimbikitsira iyi ndikofunikira - makamaka ngati muli m'gulu lomwe lili pachiwopsezo, "adatero Tang
ZOMWE MUNGACHITE PA NKHANIYI:
- Experts warn about a complete shutdown of critical infrastructure, and a crisis of never experienced proportion due to the uncontrollable spread of the Omicron variant, also known as B.
- 529) variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was initially identified in November of 2021 in South Africa and Botswana as well as in a sample from a traveler from South Africa in Hong Kong.
- “The bottom line is that boosting existing immunity (whether a vaccine or naturally acquired) does help to protect against infection/reinfection to some degree – as well as boosting existing T-cell responses – all of which will help to protect us against Omicron.
