Kei Sato anali kufunafuna zovuta zake zaka zisanu zapitazo pomwe iwo udamumenya - ndi dziko lapansi - kumaso. Viniyo anali atangoyamba kumene ntchito yodziyimira pa yunivesite ya Tokyo ndipo anali kuyesera kutulutsa Nichi gawo la kafukufuku wa HIV. "Ndinaganiza, 'Ndingatani zaka 20 kapena 30 zotsatira?'"
Adapeza Yankho Mu Oweruza - Cov - 2 Kufalikira mofulumira padziko lonse lapansi. Mu Marichi 2020, chifukwa mphekesera zomwe zimasoweka kuti Tokyo itha kuthana ndi zokometsera zomwe zingalepheretse ntchito ya abota yakale ku Kyoto. Kumeneko, adayamba kuphunzira mapuloteni a Virul omwe SARS - Cov - 2 amagwiritsa ntchito sinthani mayankho a thupi loyambirira. Sato Posakhalitsa adakhazikitsa ofufuza omwe angapitirize maphunziro a 50 pa kachilomboka.
M'zaka zisanu zokha, SARS - Cov - 2 idakhala imodzi mwama virus omwe amayang'aniridwa kwambiri padziko lapansi. Ofufuzawo afalitsa nkhani zofufuzira pafupifupi 150,000 za izi, malinga ndi vuto la mawu osungirako zakudya. Ndizo pafupifupi katatu kuchuluka kwa mapepala osindikizidwa pa HIV nthawi yomweyo. Asayansi apanganso oyang'anira oposa 17 miliyoni - COV - - 2 Genome, mpaka pano, kuposa momwe nyama ina iliyonse. Izi zapangitsa kuwona kosayerekezeka munjira zomwe kachilomboka adasintha ngati matendawo. "Kunalidi mwayi wowona mliri munthawi yeniyeni kuposa momwe zakhalapo kale kuposa kale."
Tsopano, ndi gawo ladzidzidzi la mliri kumbuyo - Onetsani galasi, akatswiri azachipatala atenga zomwe angaphunzire za kachilombo kanthawi kochepa kwambiri, kuphatikiza chisinthikedwe ndi kuyanjana kwake ndi anthu omwe ali. Nazi maphunziro anayi kuchokera pa mliri omwe ena amati amatha kupatsa mphamvu Kuyankha Padziko Lonse ku Pandemics Yamtsogolo - Koma pokhapokha ngati asayansi ndi pagulu - Ziphuphu zaumoyo zili m'malo kuti zigwiritse ntchito.
Maumboni a Virul amafotokoza nkhani
Pa 11 Januware 2020, Edward Holmes, mwazi vilowelo ku Yunivesite ya Sydney, Australia, amagawana zomwe asayansi ambiri amalingalira kuti - COV - 2 Gen) anali atalandira deta kuchokera kwa kachilombo Zhang Yongzhen ku China.
Pofika kumapeto kwa chaka, asayansi adalemba zolemba zoposa 300,000 ku malo osungira omwe amadziwika kuti Kuyambitsa Padziko Lonse Pakugawana Matenda Osiyanasiyana a Truwenza (Gisaid). Mulingo wa zosonkhanitsa deta zokhazokha kuchokera pamenepo monga momwe mavalire amagwirira. Mayiko ena adalima chuma m'malo owiritsa - - 2: Pakati pawo, pakati pawo panali United Kingdom ndi United States adapereka zoposa 8 miliyoni (onani 'geruer prolly'). Pakadali pano, asayansi m'maiko ena, kuphatikiza ku South Africa, India ndi Brazil, adawonetsa kuti kuwunika koyenera kotsika - Zolemba.
Mu miliri yakale, monga momwe za 2013-16 West African Ebola ikuwoneka pang'onopang'ono kuti isanthule momwe kachilomboka inali kusintha ngati matendawa. Koma zinadziwika mwachangu kuti SARS - - - Malangizo a 2 adafika pa volcroft, akuti Emma Hodcroft, a Emma Hodcroft, a Emma Hodcroft, a Emma Hodcroft, woimba kwamiyendo ya ku Switzerland Sukulu ya Chibalo. Amagwira ntchito Kuyesetsa Kutcha Purcestaran, zomwe zimagwiritsanso ntchito zambiri zothana ndi ma virus, monga Fluwenza, kuti amvetsetse kufalikira kwawo. "Tidapanga njira zambiri izi zomwe, m'lingaliro, zikadakhala zothandiza kwambiri," Hodcroft akuti "adatero. "Ndipo mwadzidzidzi, mu 2020, tinali ndi mwayi woyikiratu."
Poyamba, Sars - COV - Zolemba 2 zidagwiritsidwa ntchito Tsatirani kufalikira kwa kachilombo ka epinjirter yake Ku Wuhan, China, kenako padziko lonse lapansi. Mafunso awa amayankhidwa mafunso oyambirira - monga kachilomboka kafana kwambiri pakati pa anthu kapena ku nyama yomweyo kwa anthu. Zomwe zidavumbulutsa njira zomwe kachilomboka kamadutsa, ndikuwawonetsa mwachangu kwambiri akatha kufufuza kwachikhalidwe. Pambuyo pake, mwachangu - kutumiza mitundu ya kachilomboka kunayamba kuwonekera, ndikutumiza zilonda kuti azikhala ndi matenda. Ophatikizana ndi asayansi apadziko lonse lapansi ndi amateur osinthira zosemphana ndi mitengo yotsatira yomwe amayang'ana nthawi zonse akuyembekezera kusintha kwa ma virus.
"Zinatheka kutsatira chisinthiko cha kachilomboka mwatsatanetsatane kuti muwone kuti zikusintha bwanji, Ndi Sars mamiliyoni ambiri - Cov - 2 Genomes m'manja, ofufuza tsopano abwerera ndikuwaphunzira kuti amvetsetse zolimba za kachilomboka. Hodcroft sitinachitepo kanthu kale, "akutero HODCROFT.
Ma virus amasintha kuposa momwe amayembekezeredwa
Chifukwa palibe amene anaphunzirira Sabata - Asayansi, asayansi amabwera ndi malingaliro awo okhudza momwe ingasinthire. Ambiri amatsogozedwa ndi zokumana nazo ndi kachilombo kena ka RNA komwe kumayambitsa matenda opuma: fuluwenza. "Tidangokhala ndi chidziwitso chambiri chokhudza ma virus ena opumira zomwe zingayambitse ma sampics," akutero HODCROFT.
Fuluwenza imafalikira kudzera Kupeza masinthidwezomwe zimandiloza kuthetsa chitetezo cha anthu. Chifukwa palibe amene adatenga kachilombo ka SARS - - - 2 2019, asayansi ambiri sadayembekezera kusinthika kwa ma virus mpaka patakhala ndi matenda kapena kuchitirapo ma viruma.
Kutuluka kwachangu - kutumizira, kusiyanasiyana kwa SARS - Cov - - 2, monga alpha ndi Delta, adasokoneza ena. Ngakhale koyambirira kwa 2020, a SARS - Cov - 2 anali atatenga amino limodzi - - Acid Acid omwe adasinthiratu kufalikira. Ena ambiri amatsatira.
"Zomwe ndidalakwitsa ndipo sindimayembekezera kuti zingasinthe chodabwitsa," akutero Holmes. "Munawona kuthamanga kotereku kosinthana ndi kulamulidwa." Izi zinafotokozedwa kuti SARS - - - - sanalingalire bwino kwambiri pakati pa anthu atayamba ku Wuhan, mzinda wa mamiliyoni. Zitha kukhala bwino kwambiri pokhazikitsa anthu ambiri, amawonjezera.
Hols a Holss, ngakhale kuthamanga kwa kusintha kwa zomwe tawona kunali kungopanga njira yongopereka zitsanzo zotsalazo - Chikwama - 2 adatsata. Kodi ofufuza adzawona kuchuluka komweko ngati iwo ayang'ana zikamera za chimfine chomwe chinali chatsopano kwa chiwerengero cha anthu, panjira yomweyo? Zotsala kuti zitsimikizidwe.
Chikhumbo Choyambirira Chakudya chomwe SARS - 2 Tinabwera ndi chisomo chimodzi chopulumutsa: Sanakhudze chitetezo chonse chotetezedwa chomwe chimaperekedwa ndi katemera ndi matenda am'mbuyomu. Koma izi zinasintha ndi kutuluka kwa nduna ya omicron kumapeto kwa 2021, komwe kunali kosinthana ndi ma puloteni omwe amawathandiza kuti akonzere mayankho a anti-spike amalola kachilomboka kuti ulowe m'maselo omwe amayambitsa. Asayansi monga pachimake adadabwitsidwa nthawi momwe zinthu zimasinthiratu motsatizana - VIVIMENT NUMA.
Ndipo chimenecho sichinali mbali yododometsa kwambiri yamoto, akuti Ruvirra Gupta, wazachitseko ku Yunivesite ya Cambridge, UK. Patangochoka pa gulu lake, gulu lake ndi ena adawona kuti, Mosiyana ndi A SARS am'mbuyomu - Vav - ma cell a m'mphepete mwa mapapu, ogwiritsa ntchito. Gubda anati: "Kuti tilembetse kachilombo kamene kakusonyeza kuti pali zinthu zakalezi panthawi yomwe anthu anali nakope.
