Omicron miyay waxtar yar u leedahay sambabada?

Caddaynta ayaa isa soo taraysa in mutant-ka cusub ee Omicron ee fayraska Corona uu keeno astaamo ka yara daran Covid-19 marka loo eego noocyadii hore ee coronavirus-ku keeni karo, laakiin argagaxa ayaa wali adduunka qarqiyey, iyadoo laga baqayo maalmihii hore ee coronavirus, kaasoo ay ku dhinteen kumanaan qof maalin kasta. .

Sida laga soo xigtay tirooyinka rasmiga ah, in ka badan 5.4 milyan oo qof ayaa dhintay tan iyo markii uu fayrasku ka soo muuqday Shiinaha bishii Diseembar 2019. Britain, Mareykanka iyo xitaa Australia, oo muddo dheer laga badbaadiyay masiibada, ayaa diiwaangelinaya heerarkii ugu horreeyay ee caabuqyo cusub.

Daraasado cusub oo lagu sameeyay jiirarka iyo hamsters, cilmi-baarayaashu waxay ogaadeen in Omicron uu waxyeello ka yar u geysto sambabada marka loo eego noocyadii hore, halkaas oo waxyeelada mutantku ay ku kooban tahay marinnada hawada sare: sanka, cunaha iyo trachea, sida laga soo xigtay New York Times.

Inkasta oo xayawaanka ku jira tijaabooyinka ay la kulmeen, celcelis ahaan, calaamado khafiif ah, saynisyahannadu waxay si gaar ah ula yaabeen natiijooyinka laga helay hamster Syria, nooc la og yahay inuu aad u xanuunsanayo dhammaan noocyada hore ee fayraska.

"Tani waxay ahayd wax lala yaabo," ayuu yidhi Dr. Michael Diamond, oo ah khabiir ku takhasusay fayrasyada ee Jaamacadda Washington, kana mid ah qorayaasha daraasadda. Sababtoo ah dhammaan noocyada kale waxay si xun ugu dhufteen hamsters-kan."

Dheeman iyo asxaabtiisuba waxay ogaadeen in heerka omicron ee sanka hamster-ku uu la mid yahay xayawaankii hore ugu dhacay fayraska Corona. Laakiin heerarka omicron ee sambabada waxay ahaayeen tobnaad ama ka yar heerka doorsoomayaasha kale.

Daraasado cusub oo lagu sameeyay xayawaanka ayaa soo socda si loo ogaado sida ay u daran tahay omicron, gaar ahaan maadaama ay saynisyahannadu tijaabin karaan xayawaanka ku nool xaaladaha la mid ah aadanaha.

Kala duwanaanshihii hore, gaar ahaan delta, waxay dhaawac weyn u geysteen sambabada iyo dhibaato neefsashada oo daran oo mararka qaarkood horseedda dhimasho.

Caabuqa fayraska Corona wuxuu ka bilaabmaa sanka ama afka wuxuuna ku faaftaa cunaha, maadaama caabuqyada fudud uusan sii gaarin. Laakin markuu coronavirus-ku gaaro sambabada, wuxuu sababi karaa dhaawac daran.

Unugyada difaaca ee sanbabada ayaa si xad dhaaf ah uga falcelin kara fayraska, iyaga oo dila unugyada cudurka qaba oo keliya, laakiin xitaa unugyada aan la qabin. Waxa kale oo ay keeni kartaa barar degdeg ah, kaas oo keena nabarrada derbiyada dhuuban ee sambabada.

Waxaa intaa dheer, fayrasyadu waxay ka baxsan karaan sambabada dhaawacan oo u gudba dhiigga, taasoo keenta xinjirowga iyo dhaawaca xubnaha kale.

Unugyo badan oo sanbabada ku jira ayaa dusha sare ku sita borotiin la yiraahdo TMPRSS2, maadaama borotiinkani uu si badheedh ah u caawin karo in uu fayrasyada u gudbiyo unugga. Laakiin khabiir ku takhasusay cilmiga fayrasyada oo ka tirsan Jaamacadda Cambridge, Ravindra Gupta, iyo kooxdiisu waxay ogaadeen in borotiinkani aanu si fiican u qabsanayn omicron.

Natiijo ahaan, omicron ma qaadsiiso unugyada sambabada sida delta, inkastoo ay jiraan isbeddello hidde-side ah oo ku saabsan mutantkan marka loo eego Delta, taas oo ka caawisa fayrasku inuu ku dhego unugyada aadanaha.

Taas bedelkeeda, unugyada sare ee marin-haweedka uma muuqdaan inay qaadaan borotiinka loo yaqaan TMPRSS2, taas oo sharxaysa caddaynta omicrons inay ku badan yihiin sanka iyo hawo-mareenka marka loo eego sambabada.

"Dhaqanka fayraska lama saadaalin karo oo keliya isbeddellada," Dr. Gupta ayaa yidhi.

Isla mar ahaantaana, koox ka socota Jaamacadda Glasgow ayaa si madax-banaan u soo gebogebowday isku mid.

Si kastaba ha ahaatee, Dr. Diamond wuxuu sheegay inuu sugayo daraasado badan oo lagu sameeyo bini'aadamka halkii ay ka ahaan lahaayeen xayawaanka ka hor inta aan la qaadan fikradda ah in TMPRSS2 ay tahay sababta calaamadaha daran ee Omicron.

In kasta oo ay korodhay daraasadaha ay xaqiijinayaan in Omicron uu ka khatar yar yahay noocyadii hore ee coronavirus, saynisyahannadu waxay wali daraaseynayaan su'aasha ah sida ugu dhakhsaha badan ee uu u faafi karo.

"Daraasadahani waxay ka hadlayaan su'aasha ah waxa ku dhici kara sambabada, laakiin kama hadlaan arrinta gudbinta," ayay tiri Sarah Sherry, oo ku takhasusay virologist oo ka tirsan Dugsiga Caafimaadka ee Perelman ee Jaamacadda Pennsylvania.

Saynis yahanadu waxay og yihiin in qayb ka mid ah infekshanka Omikron ay ka timaaddo awoodda ay uga baxsan karto unugyada difaaca jirka, taas oo u oggolaanaysa inuu si fudud ugu gudbiyo dadka la tallaalo si ka sahlan noocyada kale.

Laakiin saynisyahannadu waxay tuhunsan yihiin in Omicron uu leeyahay faa'iidooyin kale oo bayooloji ah, sidoo kale.
