BEIJING - Waaxda caafimaadka ee gobolka Espirito Santo, Brazil, ayaa Talaadadii ku dhawaaqday in joogitaanka unugyada difaaca jirka ee IgG, oo gaar u ah fayraska SARS-CoV-2, laga helay muunado dhiig laga soo bilaabo Diseembar 2019.

Waaxda caafimaadka ayaa sheegtay in 7,370 muunado dhiig ah laga soo qaaday bukaanada looga shakisan yahay inay qabaan cudurka dengue iyo chikungunya intii u dhaxaysay Diseembar 2019 iyo Juun 2020.

Markii la falanqeeyay muunadaha, unugyada difaaca jirka ee IgG ayaa laga helay 210 qof, kuwaas oo 16 kiis ay soo jeediyeen in cudurka coronavirus-ka cusub uu ka jiro 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 waxaa la ururiyay Diseembar 18, 2019.

Waaxda caafimaadku waxay sheegtay in ay qaadato qiyaastii 20 maalmood in bukaanku gaaro heerarka IgG ee la ogaan karo ka dib infekshanka, sidaa darteed infekshanku wuxuu dhici karay inta u dhaxaysa dabayaaqada Noofambar iyo horraanta Diseembar 2019.

Wasaaradda Caafimaadka ee Brazil ayaa ku amartay dowladda inay sameyso baaritaanno qoto dheer oo ku saabsan cudurrada faafa si loo xaqiijiyo.

Natiijooyinka laga helay Brazil ayaa ah kuwii ugu dambeeyay ee ka mid ah daraasadaha adduunka oo dhan kuwaas oo ku daray caddayn sii kordheysa oo muujinaysa in COVID-19 si aamusnaan ah ugu faafay dibadda Shiinaha ka hor sidii hore loo malaynayay.

Cilmi-baarayaal ka socda Jaamacadda Milan ayaa dhawaan ogaaday in haweeney ku nool magaalada waqooyiga Talyaaniga ay qaaday cudurka COVID-19 bishii Nofeembar 2019, sida ay sheegeen warbaahinta.

Iyada oo loo marayo laba farsamo oo kala duwan oo ku saabsan unugyada maqaarka, cilmi-baarayaashu waxay ku ogaadeen biopsy haweeney 25 jir ah jiritaanka taxanaha hidde-sidaha RNA ee fayraska SARS-CoV-2 oo dib ugu soo laabanaya Noofambar 2019, sida laga soo xigtay wargeyska maalinlaha ah ee gobolka Talyaaniga ee L'Unione Sarda.

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

"Waxaan la yaabay haddii aan ka heli karno caddayn ku saabsan SARS-CoV-2 maqaarka bukaanada qaba cudurrada maqaarka oo keliya ka hor inta aan si rasmi ah loo aqoonsanayn marxaladda cudurka faafa," ayuu yiri Gianotti, isagoo raaciyay "waxaan ka helnay 'faraha' COVID-19 unugyada maqaarka."

Warbixintu waxay sheegtay in iyadoo lagu saleynayo xogta caalamiga ah, tani waa "caddaynta ugu da'da weyn ee muujinaysa jiritaanka fayraska SARS-CoV-2 ee ku jira bini'aadamka."

Dabayaaqadii Abriil 2020, Michael Melham, duqa magaalada Belleville ee gobolka New Jersey ee Mareykanka, ayaa sheegay inuu laga helay COVID-19 antibodies wuxuuna aaminsanaa inuu fayraska qaaday bishii Nofeembar 2019, inkastoo dhakhtar uu sheegay in waxa Melham la kulmay ay ahayd hargab oo keliya.

Faransiiska, saynisyahano ayaa ogaaday in nin uu ku dhacay COVID-19 bishii Diseembar 2019, qiyaastii bil ka hor inta aan kiisaska ugu horreeya si rasmi ah looga diiwaan gelin Yurub.

Iyadoo soo xiganaysa dhakhtar ka tirsan isbitaallada Avicenne iyo Jean-Verdier ee u dhow Paris, BBC News ayaa werisay bishii Maajo 2020 in bukaanka "uu cudurka qaaday intii u dhaxaysay 14 iyo 22 Diseembar (2019), maadaama calaamadaha coronavirus ay qaataan inta u dhaxaysa shan iyo 14 maalmood in la arko."

Dalka Spain, cilmi-baarayaal ka tirsan Jaamacadda Barcelona, ​​oo ka mid ah jaamacadaha ugu caansan dalka, ayaa ogaaday jiritaanka hidde-sideyaasha fayraska ee muunadaha biyaha wasakhda ah ee la ururiyay Maarso 12, 2019, sida ay jaamacaddu ku sheegtay bayaan ay soo saartay bishii Juun 2020.

Dalka Talyaaniga, cilmi-baaris ay samaysay Machadka Qaranka ee Kansarka ee Milan, oo la daabacay Noofambar 2020, ayaa muujisay in 11.6 boqolkiiba 959 mutadawiciin caafimaad qaba oo ka qayb qaatay tijaabada baaritaanka kansarka sambabada intii u dhaxaysay Sebtembar 2019 ilaa Maarso 2020 ay sameeyeen unugyada difaaca jirka ee COVID-19 kahor Febraayo 2020 markii kiiskii ugu horreeyay ee rasmiga ahaa laga diiwaan geliyay dalka, iyadoo afar kiis laga soo qaaday daraasadda ay socotay usbuucii ugu horreeyay ee Oktoobar 2019, taasoo la macno ah in dadkaas ay qaadeen cudurka Sebtembar 2019.

Noofambar 30, 2020, daraasad ay samaysay Xarumaha Xakamaynta iyo Kahortagga Cudurrada ee Mareykanka (CDC) ayaa lagu ogaaday in COVID-19 uu u badan yahay inuu ka dhacay Mareykanka horraantii bartamihii Diseembar 2019, toddobaadyo ka hor inta aan fayraska markii ugu horreysay laga helin Shiinaha.

Sida laga soo xigtay daraasadda lagu daabacay khadka tooska ah ee joornaalka Clinical Infectious Diseases, cilmi-baarayaasha CDC waxay tijaabiyeen muunado dhiig ah oo laga soo qaaday 7,389 deeqo dhiig oo caadi ah oo ay ururisay Laanqeyrta Cas ee Mareykanka laga bilaabo Diseembar 13, 2019 ilaa Janaayo 17, 2020 si loo ogaado unugyada difaaca jirka ee gaarka u ah coronavirus-ka cusub.

Caabuqyada COVID-19 "waxaa laga yaabaa inay ka jireen Mareykanka bishii Diseembar 2019," qiyaastii bil ka hor kiiskii ugu horreeyay ee rasmiga ahaa ee dalka laga helay Janaayo 19, 2020, sida ay qoreen saynisyahannada CDC.

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

Taariikh ahaan, meesha markii ugu horreysay laga soo sheegay fayras badanaa ma ahayn meeshii uu ka soo jeeday. Tusaale ahaan, caabuqa HIV waxaa markii ugu horreysay soo sheegay Mareykanka, haddana waxaa dhici karta in fayrasku uusan asal ahaan ka soo jeedin Mareykanka. Caddeymo badan ayaa muujinaya in hargabka Isbaanishku uusan ka soo bixin Spain.

Marka laga hadlayo COVID-19, in qofku noqdo qofkii ugu horreeyay ee soo sheega fayraska macnaheedu maaha in fayrasku uu asal ahaan ka soo jeedo magaalada Wuhan ee Shiinaha.

Marka laga hadlayo daraasadahan, Hay'adda Caafimaadka Adduunka (WHO) waxay sheegtay inay "si dhab ah u qaadan doonto ogaanshaha kasta ee Faransiiska, Isbaanishka, iyo Talyaaniga, waxaanan baari doonnaa mid kasta oo ka mid ah."

"Kama joogsan doonno inaan ogaanno runta ku saabsan asalka fayraska, laakiin waxaan ku saleyneynaa sayniska, annagoo aan siyaasadeyn ama aan isku dayin inaan xiisad ka abuurno geeddi-socodka," ayuu yiri Agaasimaha Guud ee WHO Tedros Adhanom Ghebreyesus dabayaaqadii Noofambar 2020.
