BEIJING - Waaxda caafimaadka ee gobolka Espirito Santo, Brazil, ayaa ku dhawaaqday Talaadadii in joogitaanka unugyada difaaca jirka ee IgG, gaar ahaan fayraska SARS-CoV-2, laga helay muunadaha serum laga soo bilaabo Disembar 2019.

Waaxda caafimaadka ayaa sheegtay in 7,370 muunado serum laga soo aruuriyay inta u dhexeysa Disembar 2019 iyo Juun 2020 bukaannada looga shakisan yahay inay qabaan cudurka dengue iyo chikungunya.

Iyada oo muunado la falanqeeyay, unugyada difaaca jirka ee IgG ayaa laga helay 210 qof, kuwaas oo 16 xaaladood ay soo jeediyeen joogitaanka coronavirus-ga cusub ee gobolka ka hor inta uusan Brazil ku dhawaaqin kiiskeedii ugu horreeyay ee si rasmi ah loo xaqiijiyay Febraayo 26, 2020. Mid ka mid ah kiisaska ayaa la soo aruuriyay Dec. 18, 2019.

Waaxda caafimaadka ayaa sheegtay in ay ku qaadato ilaa 20 maalmood in bukaanku gaaro heerarka la ogaan karo ee IgG ka dib infekshanka, sidaa darteed infekshanku wuxuu dhici karaa inta u dhaxaysa dabayaaqadii Noofambar iyo horraanta Disembar 2019.

Wasaaradda caafimaadka Brazil ayaa ku amartay gobolka inay sameeyaan baaritaanno qotodheer oo cudurka faafa ah si loo xaqiijiyo dheeraad ah.

Natiijooyinka ka soo baxay Brazil ayaa ah kii ugu dambeeyay ee daraasadaha adduunka oo dhan oo ku daray caddaynta sii kordheysa ee ah in COVID-19 uu aamusnaan ugu faafay meel ka baxsan Shiinaha ka hor sidii loo maleynayay.

Cilmi-baarayaal ka socda Jaamacadda Milano ayaa dhawaan ogaaday in haweeney ku nool waqooyiga magaalada Talyaaniga uu ku dhacay COVID-19 bishii Nofembar 2019, sida ay sheegtay warbaahintu.

Iyada oo loo marayo laba farsamooyin oo kala duwan oo ku saabsan unugyada maqaarka, cilmi-baarayaashu waxay ku caddeeyeen biopsy haweeney 25 jir ah joogitaanka taxanaha hiddo-wadaha RNA ee fayraska SARS-CoV-2 ilaa Noofambar 2019, sida laga soo xigtay wargeyska maalinlaha ah ee gobolka Talyaaniga L' Midowga Sarda.

"Waxaa jira, masiibadan, kiisas calaamadda kaliya ee caabuqa COVID-19 ay tahay cudurka maqaarka maqaarka," Raffaele Gianotti, oo isku dubariday cilmi-baarista, ayaa laga soo xigtay wargeysku isagoo leh.

"Waxaan la yaabay haddii aan ka heli karno caddaynta SARS-CoV-2 maqaarka bukaannada qaba cudurrada maqaarka ka hor inta aan si rasmi ah loo aqoonsan wejiga faafa," ayuu yiri Gianotti, isagoo raaciyay "waxaan ka helnay 'faraha' COVID-19 maqaarka. nudaha.”

Iyada oo ku saleysan xogta caalamiga ah, tani waa "caddeeymihii ugu da'da weynaa ee joogitaanka fayraska SARS-CoV-2 ee bini'aadamka," ayaa lagu yiri warbixinta.

Dabayaaqadii Abriil 2020, Michael Melham, duqa magaalada Belleville ee gobolka New Jersey ee Mareykanka, ayaa sheegay inuu tijaabiyey cudurka COVID-19 unugyada difaaca jirka oo uu rumeysan yahay inuu ku dhacay fayraska Noofambar 2019, in kasta oo uu dhakhtarku sheegay in loo maleynayo waxa Melham haysto. waayo-aragnimadu waxay ahayd hargab kaliya.

Dalka Faransiiska, saynisyahannadu waxay heleen nin qaba COVID-19 bishii Diseembar 2019, qiyaastii hal bil ka hor inta aan kiisaska ugu horreeya si rasmi ah Yurub looga diiwaangelin.

Iyadoo la tixraacayo dhakhtar ka shaqeeya cisbitaalada Avicenne iyo Jean-Verdier ee u dhow Paris, BBC News ayaa soo wariyay bishii Maajo 2020 in bukaanku "ay qasab tahay in uu cudurka qaaday intii u dhaxaysay 14 iyo 22 Diseembar (2019), maadaama calaamadaha coronavirus ay qaadanayaan inta u dhaxaysa shan iyo 14 maalmood inay soo muuqdaan."

Dalka Spain, cilmi-baarayaal ka tirsan Jaamacadda Barcelona, ​​oo ka mid ah jaamacadaha ugu caansan dalka, ayaa ogaaday jiritaanka genome-ka fayraska ee muunado biyaha wasakhda ah oo la uruuriyay 12-kii Maarso, 2019, jaamacaddu waxay ku sheegtay bayaan ay soo saartay Juun 2020.

Dalka Talyaaniga, cilmi-baaris uu sameeyay Machadka Kansarka Qaranka ee Milan, oo la daabacay Noofambar 2020, ayaa muujisay in 11.6 boqolkiiba 959 mutadawiciin caafimaad qaba oo ka qaybqaatay tijaabada baaritaanka kansarka sanbabada intii u dhaxaysay Sebtembar 2019 ilaa Maarso 2020 ay sameeyeen unugyada ka hortagga COVID-19 kahor Febraayo 2020 Markii kiiskii ugu horreeyay ee rasmi ah laga diiwaangeliyay dalka, iyadoo afar xaaladood laga soo bilaabo daraasadda ilaa usbuucii ugu horreeyay ee Oktoobar 2019, taas oo macnaheedu yahay in dadkaas ay qaadeen Sebtember 2019.

Noofambar 30, 2020, daraasad ay samaysay Xarunta Xakamaynta iyo Kahortagga Cudurrada ee Mareykanka (CDC) ayaa lagu ogaaday in COVID-19 ay u badan tahay inuu ku sugan yahay Mareykanka horraantii Disembar 2019, toddobaadyo ka hor inta aan fayraska laga helin Shiinaha.

Sida laga soo xigtay daraasadda lagu daabacay khadka tooska ah joornaalka Cudurrada Cudurrada, cilmi-baarayaasha CDC waxay tijaabiyeen muunado dhiig ah 7,389 deeqo dhiig oo joogto ah oo ay soo aruurisay Laanqeyrta Cas ee Mareykanka laga soo bilaabo Disembar 13, 2019 illaa Jan 17, 2020 unugyada difaaca gaarka ah ee coronavirus-ka cusub.

Infekshannada COVID-19 “waxaa laga yaabaa inay joogeen Mareykanka Diseembar 2019,” qiyaastii hal bil ka hor kiiskii ugu horreeyay ee rasmi ah ee dalka Jan 19, 2020, saynisyahannada CDC ayaa qoray.

Natiijooyinkani waa sawir kale oo muujinaya sida ay u adag tahay in la xalliyo halxiraalaha sayniska ee raadinta isha fayraska.

Taariikh ahaan, meeshii ugu horreysay ee fayraska laga soo sheegay inta badan waxay noqotay mid aan ahayn meeshii uu ka yimid. Infekshanka HIV, tusaale ahaan, waxaa markii ugu horreysay soo sheegay Mareykanka, hase ahaatee waxaa laga yaabaa in sidoo kale ay suurtagal tahay in fayrasku uusan lahayn asalkiisa Mareykanka. Iyo cadaymo badan oo badan ayaa cadeynaya in hargabka Isbaanishka uusan ka soo bixin Spain.

Ilaa iyo inta laga hadlayo COVID-19, noqoshada qofka ugu horreeya ee ka warbixiya fayraska macnaheedu maaha in fayrasku asalkiisu ka yimid magaalada Wuhan ee Shiinaha.

Marka laga hadlayo daraasaddan, Ururka Caafimaadka Adduunka (WHO) wuxuu sheegay inay "si dhab ah u qaadan doonaan baaritaan kasta oo ka dhaca Faransiiska, Spain, gudaha Talyaaniga, waxaanan baari doonnaa mid kasta oo iyaga ka mid ah."

"Kama joojin doonno ogaanshaha runta ku saabsan asalka fayraska, laakiin ku saleysan sayniska, ayada oo aan la siyaasadeynin ama aan isku dayeyno inaan xiisad ka abuurno geeddi-socodka," Agaasimaha Guud ee WHO Tedros Adhanom Ghebreyesus ayaa yiri dabayaaqadii Noofambar 2020.
