2024 Tus sau: Malcolm Clapton | [email protected]. Kawg hloov kho: 2023-12-17 03:58

Kev npaj txhij txog, tsis tas yuav ua kom cov haujlwm ua haujlwm ntawm cov tshuaj tiv thaiv sai.

Kaum ob ntawm cov tuam txhab biotechnology thiab cov tsev kawm tshawb fawb tau sib tw tawm tsam tus kabmob kis thoob ntiaj teb los tsim cov tshuaj tiv thaiv sib txawv rau tus kabmob tshiab SARS-CoV-2. Peb tab tom nrhiav seb cov thev naus laus zis twg siv los txhim kho lawv, nws yuav siv sijhawm ntev npaum li cas kom txog thaum cov tshuaj tiv thaiv COVID-19 tuaj yeem txhaj tshuaj tiv thaiv, thiab seb cov tshuaj tiv thaiv yav tom ntej puas tuaj yeem tiv thaiv kev sib kis.

Txhua zaus tib neeg ntsib tus kab mob tshiab, peb haiv neeg pib ib txhij: rau tshuaj, kuaj kab mob thiab tshuaj tiv thaiv. Lub lim tiam dhau los, Lub Chaw Tshawb Fawb ntawm Rospotrebnadzor tau pib sim tshuaj tiv thaiv tus kabmob tshiab, sim tshuaj tiv thaiv tus kabmob coronavirus rau tsiaj, thiab hauv Tebchaws Meskas, NIH kev sim tshuaj ntsuam xyuas tshuaj tiv thaiv rau COVID-19 pib. Puas yog qhov no txhais tau hais tias kev yeej ntawm kev sib kis tau ze?

Raws li WHO, kwv yees li 40 lub chaw kuaj mob thoob ntiaj teb tau tshaj tawm DRAFT thaj chaw ntawm cov tshuaj tiv thaiv COVID-19 - Lub Peb Hlis 20, 2020 tias lawv tab tom tsim cov tshuaj tiv thaiv tus kabmob coronavirus. Thiab txawm hais tias muaj cov thawj coj pom tseeb ntawm lawv - piv txwv li, Suav tuam txhab CanSino Biologics, uas tau txais RECOMBINANT NOVEL CORONAVIRUS VACCINE (ADENOVIRUS TYPE 5 VECTOR) POPROVED FOR CLINICAL TRIAL tso cai rau tib neeg kev sim, thiab American Moderna, uas twb muaj lawm. pib lawv, - Tam sim no nws nyuaj rau twv seb lub tuam txhab twg yuav yeej qhov kev sib tw no, thiab qhov tseem ceeb tshaj plaws, seb qhov kev tsim cov tshuaj tiv thaiv yuav dhau los ntawm kev kis tus kabmob coronavirus. Kev vam meej hauv kev sib tw no tsis yog tsawg kawg ntawm kev xaiv riam phom, uas yog, ntawm lub hauv paus ntsiab lus ntawm kev tsim tshuaj tiv thaiv.

Tus kab mob tuag yog tus kab mob phem

Nyob rau hauv tsev kawm ntawv cov phau ntawv, lawv feem ntau sau hais tias ib tug tua los yog tsis muaj zog kab mob yog siv rau kev txhaj tshuaj. Tab sis cov ntaub ntawv no yog me ntsis outdated. "Inactivated (" tua ". - Approx. N + 1.) Thiab attenuated (tsis muaj zog. - Approx. N + 1.) Cov tshuaj tiv thaiv tau tsim thiab qhia nyob rau hauv nruab nrab ntawm lub xyoo pua xeem, thiab nws yog ib qho nyuaj rau xav txog lawv niaj hnub, - piav qhia hauv kev sib tham nrog N +1 Olga Karpova, Lub taub hau ntawm Lub Tsev Haujlwm Saib Xyuas Kev Tiv Thaiv Kab Mob, Kws Qhia Ntawv ntawm Biology, Lomonosov Moscow State University. - Nws yog kim. Nws nyuaj rau kev thauj thiab khaws cia, ntau cov tshuaj tiv thaiv mus txog qhov chaw uas lawv xav tau (yog tias peb tab tom tham, piv txwv li, txog Africa) nyob rau hauv lub xeev zoo li no thaum lawv tsis tiv thaiv ib tus neeg ntxiv lawm."

Ntxiv mus, nws tsis ruaj ntseg. Yuav kom tau txais koob tshuaj ntau ntawm tus kab mob "tua tuag", koj yuav tsum ua ntej kom tau txais kev ua neej nyob ntau, thiab qhov no yuav ua rau kom cov khoom siv hauv chav kuaj. Tom qab ntawd nws yuav tsum tau neutralized - rau qhov no lawv siv, piv txwv li, ultraviolet los yog formalin.

Tab sis qhov twg yog qhov lav tias ntawm cov neeg coob ntawm "tuag" cov kab mob kis yuav tsis muaj ntxiv uas tuaj yeem ua rau mob?

Nrog rau cov kab mob tsis muaj zog, nws tseem nyuaj dua. Tam sim no, txhawm rau ua kom tsis muaj zog, tus kab mob raug yuam kom hloov pauv, thiab tom qab ntawd xaiv cov kab mob hnyav tshaj plaws. Tab sis qhov no ua rau muaj tus kab mob nrog cov khoom tshiab, thiab tsis yog txhua tus ntawm lawv tuaj yeem kwv yees ua ntej. Ib zaug ntxiv, qhov twg yog qhov lees paub tias, ib zaug hauv lub cev, tus kab mob yuav tsis hloov mus ntxiv thiab tsim "cov xeeb ntxwv" txawm tias "kev phem" ntau dua li qub?

Yog li ntawd, cov kab mob "tua" thiab "tsis tua" tsis tshua siv niaj hnub no. Piv txwv li, ntawm cov tshuaj tiv thaiv kab mob khaub thuas niaj hnub no, "cov kab mob tsis zoo" yog nyob rau hauv cov haiv neeg tsawg - Cov tshuaj tiv thaiv kab mob khaub thuas tom ntej: cov cib fim thiab cov teeb meem nyob hauv cov neeg tsawg - tsuas yog 2 ntawm 18 cov tshuaj tiv thaiv tau pom zoo hauv Tebchaws Europe thiab Tebchaws Meskas los ntawm 2020. Ntawm ntau dua 40 txoj haujlwm ntawm cov tshuaj tiv thaiv tus kabmob coronavirus, tsuas yog ib qho raug teeb tsa raws li lub hauv paus ntsiab lus no - Indian Institute of Serum tau koom nrog.

Sib faib thiab txhaj tshuaj tiv thaiv

Nws muaj kev nyab xeeb ntau dua los qhia txog lub cev tiv thaiv kab mob tsis yog rau tag nrho tus kab mob, tab sis rau ib feem ntawm nws. Txhawm rau ua qhov no, koj yuav tsum xaiv cov protein uas "cov tub ceev xwm sab hauv" ntawm tus neeg yuav tuaj yeem paub meej tus kab mob no. Raws li txoj cai, qhov no yog cov protein ntau, nrog kev pab ntawm cov kab mob nkag mus rau hauv lub hlwb. Tom qab ntawd koj yuav tsum tau txais qee cov kab lis kev cai ntawm tes los tsim cov protein no ntawm kev lag luam. Qhov no yog ua tiav nrog kev pab ntawm genetic engineering, uas yog vim li cas cov proteins no hu ua genetically engineered, los yog recombinant.

Karpova hais tias "Kuv ntseeg tias cov tshuaj tiv thaiv yuav tsum rov ua dua, thiab tsis muaj dab tsi ntxiv," - Ntxiv mus, cov no yuav tsum yog cov tshuaj tiv thaiv ntawm cov neeg nqa khoom, uas yog, cov proteins ntawm tus kab mob yuav tsum nyob rau qee yam ntawm cov neeg nqa khoom. Qhov tseeb yog tias los ntawm lawv tus kheej lawv (cov protein) tsis yog immunogenic. Yog tias cov proteins uas tsis tshua muaj molecular-yuag tau siv los ua tshuaj tiv thaiv, lawv yuav tsis tsim kev tiv thaiv kab mob, lub cev yuav tsis hnov mob rau lawv, yog li cov khoom siv thauj khoom yog qhov tsim nyog."

Raws li tus neeg nqa khoom zoo li no, cov kws tshawb fawb los ntawm Moscow State University thov kom siv tus kab mob luam yeeb mosaic. Tobacco mosaic virus - "Wikipedia" (qhov no, los ntawm txoj kev, yog thawj tus kab mob uas tib neeg pom). Nws feem ntau zoo li ib daim nyias nyias, tab sis thaum rhuab, nws yuav siv lub pob. Karpova hais tias "Nws ruaj khov, nws muaj qhov tshwj xeeb adsorption zog, nws nyiam cov proteins rau nws tus kheej," Karpova hais. "Ntawm nws qhov chaw, koj tuaj yeem tso cov proteins me me, cov antigens heev." Yog tias koj npog cov kab mob luam yeeb mosaic nrog cov proteins uas muaj tus kabmob coronavirus, tom qab ntawd rau lub cev nws hloov mus ua kev coj ua ntawm SARS - CoV - 2 tus kabmob kis. Karpova sau hais tias "Tus kab mob luam yeeb mosaic," yog ib qho tshuaj tiv thaiv kab mob zoo rau lub cev. Nyob rau tib lub sijhawm, txij li cov kab mob cog tsis tuaj yeem kis rau tsiaj, suav nrog tib neeg, peb ua cov khoom muaj kev nyab xeeb kiag li."

Kev nyab xeeb ntawm ntau txoj hauv kev cuam tshuam nrog cov proteins sib xyaw ua ke tau ua rau lawv nyiam tshaj plaws - tsawg kawg yog kaum lub tuam txhab tam sim no tau sim kom tau cov protein zoo li no rau tus mob coronavirus. Tsis tas li ntawd, ntau tus siv lwm cov kab mob cab - piv txwv li, cov kab mob adenoviral lossis txawm hloov cov kab mob qhua pias thiab cov kab mob me me uas kis rau tib neeg lub hlwb thiab muab ntau ntxiv nrog rau cov kab mob coronavirus. Txawm li cas los xij, cov txheej txheem no tsis yog qhov ceev tshaj plaws, vim tias nws yog qhov tsim nyog los tsim kom muaj cov protein ntau thiab cov kab mob hauv cov kab lis kev cai ntawm tes.

Cov noob liab qab

Cov kauj ruam tsim cov protein ntau hauv cov kab lis kev cai ntawm tes tuaj yeem ua kom luv thiab nrawm los ntawm kev ua kom lub cev cov hlwb tsim cov kab mob kis ntawm lawv tus kheej. Cov tshuaj tiv thaiv kab mob ua haujlwm raws li lub hauv paus ntsiab lus no - "liab qab" cov khoom siv caj ces - kab mob DNA lossis RNA - tuaj yeem tso rau hauv tib neeg lub hlwb. DNA feem ntau yog txhaj rau hauv cov hlwb uas siv electroporation, uas yog, nrog rau kev txhaj tshuaj, ib tus neeg tau txais lub teeb tawm, vim li ntawd, qhov permeability ntawm cell membranes nce, thiab DNA strands nkag mus rau hauv. RNA yog xa nrog lipid vesicles. Ib txoj hauv kev los sis lwm qhov, cov hlwb pib tsim cov kab mob kis kab mob thiab ua kom pom nws rau lub cev tiv thaiv kab mob, thiab nws nthuav tawm lub cev tiv thaiv kab mob txawm tias tsis muaj tus kab mob.

Txoj kev no yog qhov tshiab heev, tsis muaj cov tshuaj tiv thaiv hauv ntiaj teb uas yuav ua haujlwm ntawm txoj cai no.

Txawm li cas los xij, raws li WHO, xya lub tuam txhab ib zaug tau sim ua tshuaj tiv thaiv tus kabmob coronavirus raws li nws. Nov yog txoj hauv kev coj los ntawm Moderna Therapeutics, tus thawj coj Asmeskas hauv kev sib tw tshuaj tiv thaiv. Nws kuj tau raug xaiv rau lawv tus kheej los ntawm peb tus neeg tuaj koom ntxiv hauv kev sib tw los ntawm Russia: Vector Scientific Center hauv Novosibirsk (raws li Rospotrebnadzor, nws sim ntau li 6 tus qauv tshuaj tiv thaiv tib lub sijhawm, thiab ib qho ntawm lawv yog raws li RNA), Biocad thiab Scientific and Clinical Center for Precision and regenerative medicine price Kazan.

Albert Rizvanov, tus thawj coj ntawm Lub Chaw, tus xibfwb ntawm Department of Genetics ntawm Lub Tsev Haujlwm Saib Xyuas Kev Kho Mob thiab Biology ntawm Kazan Federal University hais tias "Hauv txoj cai, nws tsis yooj yim heev los tsim cov tshuaj tiv thaiv." "Cov tshuaj tiv thaiv kab mob yog qhov ceev tshaj plaws ntawm txoj kev loj hlob, vim tias nws txaus los tsim cov noob caj noob ces." Cov tshuaj tiv thaiv, uas tab tom ua haujlwm ntawm Lub Chaw, yuav tsum tua ntau lub hom phiaj ib zaug: DNA strand nrog ntau tus kab mob kis tau raug txhaj rau hauv cov hlwb tib lub sijhawm. Raws li qhov tshwm sim, cov hlwb yuav tsim tsis yog ib qho kab mob kis kab mob, tab sis ob peb zaug ib zaug.

Tsis tas li ntawd, raws li Rizvanov, cov tshuaj tiv thaiv DNA yuav pheej yig dua li lwm tus hauv kev tsim khoom. "Peb zoo li Space X," tus kws tshawb fawb tso dag. - Peb cov qauv kev tsim kho tus nqi tsuas yog ob peb lab rubles. Txawm li cas los xij, kev tsim qauv tsuas yog qhov kawg ntawm cov dej khov nab kuab, thiab kev sim nrog tus kab mob nyob yog qhov kev txiav txim sib txawv kiag li."

Kev tsis ncaj ncees thiab kev dag

Thaum cov tshuaj tiv thaiv tau hloov pauv los ntawm kev txhim kho theoretical mus rau hauv cov khoom tshawb fawb, cov teeb meem thiab kev txwv pib loj hlob zoo li nceb. Thiab nyiaj txiag tsuas yog ib qho teeb meem xwb. Raws li Karpova, Moscow State University twb muaj cov qauv ntawm cov tshuaj tiv thaiv, tab sis kev sim ntxiv yuav xav tau kev koom tes nrog lwm lub koom haum. Hauv cov kauj ruam tom ntej, lawv npaj yuav kuaj kev nyab xeeb thiab kev tiv thaiv kab mob, thiab qhov no tuaj yeem ua tiav hauv cov phab ntsa hauv tsev kawm ntawv. Tab sis sai li sai tau koj yuav tsum ntsuas qhov ua tau zoo ntawm cov tshuaj tiv thaiv, koj yuav tsum ua haujlwm nrog cov kab mob, thiab qhov no yog txwv tsis pub nyob rau hauv lub tsev kawm ntawv.

Tsis tas li ntawd, yuav tsum muaj tsiaj tshwj xeeb. Qhov tseeb yog tias cov nas nyob hauv chav sim no tsis muaj mob nrog txhua tus kab mob tib neeg, thiab daim duab ntawm tus kab mob tuaj yeem sib txawv heev. Yog li ntawd, cov tshuaj tiv thaiv feem ntau raug sim hauv ferrets. Yog tias lub hom phiaj yog ua haujlwm nrog cov nas, tom qab ntawd cov nas hloov pauv yog xav tau, uas ua rau lawv lub hlwb raws nraim tib yam receptors uas tus mob coronavirus "clings" hauv tus neeg mob lub cev. Cov nas no tsis pheej yig Ace2 CONSTITUTIVE KNOCKOUT (tsawg lossis nees nkaum txhiab daus las ib kab). Muaj tseeb tiag, qee zaum koj tuaj yeem txuag nyiaj - yuav ob peb tus tib neeg thiab yug lawv hauv chav kuaj - tab sis qhov no ua rau lub sijhawm kuaj preclinical.

Thiab yog tias peb tseem muaj peev xwm daws tau qhov teeb meem ntawm kev nyiaj txiag, ces lub sij hawm tseem yog ib qho nyuaj insurmountable. Raws li Rizvanov, cov tshuaj tiv thaiv feem ntau siv lub hlis thiab xyoo los tsim. "Tsis tshua muaj tsawg dua ib xyoos, feem ntau ntau," nws hais. Lub taub hau ntawm Tsoom Fwv Teb Chaws Biomedical Agency (lawv tab tom tsim cov tshuaj tiv thaiv raws li cov protein sib txuas) Veronika Skvortsova tau hais tias FMBA ntawm Russia yuav tau txais thawj qhov kev sim ntawm cov qauv tshuaj tiv thaiv kab mob coronavirus thaum Lub Rau Hli 2020, tias cov tshuaj tiv thaiv tiav tuaj yeem tshwm sim hauv 11 hli.

Muaj ob peb theem ntawm cov txheej txheem tuaj yeem ua kom nrawm. Qhov pom tseeb tshaj plaws yog kev txhim kho. Lub tuam txhab Asmeskas Moderna tau ua tus thawj coj vim nws tau tsim cov tshuaj tiv thaiv mRNA tau ntev. Thiab ua kom lwm tus, lawv muaj txaus ntawm cov genome decoded ntawm tus kab mob tshiab. Cov pab pawg Lavxias los ntawm Moscow thiab Kazan kuj tau ua haujlwm ntawm lawv cov thev naus laus zis tau ntau xyoo thiab tso siab rau cov txiaj ntsig ntawm kev sim lawv cov tshuaj tiv thaiv yav dhau los tiv thaiv lwm yam kab mob.

Qhov zoo tshaj plaws yuav yog lub platform uas tso cai rau koj los tsim cov tshuaj tiv thaiv tshiab los ntawm tus qauv sai. Cov kws tshawb fawb los ntawm Moscow State University tab tom tsim cov phiaj xwm zoo li no.

Karpova hais tias "Ntawm ntawm peb cov khoom, peb tuaj yeem tso cov protein ntau ntawm cov kab mob thiab ib txhij tiv thaiv COVID-19, SARS thiab MERS. Peb txawm xav tias peb tuaj yeem tiv thaiv tau cov kab mob no yav tom ntej. Muaj 39 tus kabmob coronaviruses, qee tus ntawm lawv nyob ze rau tib neeg tus kabmob coronaviruses, thiab nws paub meej tias nws yog dab tsi los kov yeej cov kab thaiv kab mob ("dhia" tus kab mob los ntawm puav rau tib neeg. - Nco ntsoov N + 1.). Tab sis yog tias muaj cov tshuaj tiv thaiv zoo li Lego, peb tuaj yeem muab tso rau ntawm nws cov protein ntawm qee tus kab mob uas tshwm sim rau qee qhov. Peb yuav ua qhov no hauv ob lub hlis - peb yuav hloov lossis ntxiv cov proteins no. Yog tias cov tshuaj tiv thaiv zoo li no tau muaj nyob rau lub Kaum Ob Hlis 2019, thiab tib neeg tau txhaj tshuaj tsawg kawg hauv Suav teb, qhov no yuav tsis kis mus ntxiv."

Cov theem tom ntej yog kev ntsuam xyuas preclinical, uas yog, ua haujlwm nrog cov tsiaj hauv chav kuaj. Nws tsis yog cov txheej txheem ntev tshaj plaws, tab sis nws tuaj yeem yeej ntawm nws cov nqi thaum ua ke nrog kev sim tshuaj hauv tib neeg. Moderna ua li ntawd - lub tuam txhab txwv nws tus kheej mus rau kev soj ntsuam ceev ceev thiab mus ncaj nraim rau tib neeg kev tshawb fawb. Txawm li cas los xij, nws tsim nyog nco ntsoov tias cov tshuaj uas nws tab tom sim yog ib qho kev nyab xeeb tshaj plaws. Txij li Moderna tsis siv cov kab mob los yog cov protein sib xyaw ua ke, muaj feem tsawg heev uas cov neeg tuaj yeem pab dawb yuav muaj kev mob tshwm sim - lub cev tiv thaiv kab mob tsuas yog tsis muaj dab tsi ua rau mob hnyav. Qhov phem tshaj plaws uas tuaj yeem tshwm sim yog qhov tshuaj tiv thaiv tsis zoo. Tab sis qhov no tseem yuav tau txheeb xyuas.

Tab sis kev tsim cov tshuaj tiv thaiv, pom meej, tsis yog theem txwv. Rizvanov piav qhia tias "Qhov no tsis yog qhov nyuaj tshaj li niaj zaus biotechnological tsim cov proteins sib xyaw ua ke," Rizvanov piav qhia. Raws li nws, cov nroj tsuag tuaj yeem tsim tau ib lab koob tshuaj tiv thaiv zoo li no hauv ib hlis. Olga Karpova muab qhov kev kwv yees zoo sib xws: peb lub hlis rau ib lab koob tshuaj.

Koj puas xav tau tshuaj tiv thaiv?

Seb nws puas tsim nyog txiav rov qab rau kev sim tshuaj yog qhov taw qhia moot. Ua ntej, nws yog tus txheej txheem qeeb hauv nws tus kheej. Feem ntau, cov tshuaj tiv thaiv yuav tsum tau txhaj rau ntau theem: yog tias tus kab mob tsis sib npaug ntawm nws tus kheej hauv lub cev, tom qab ntawd nws raug tshem tawm sai, thiab nws cov concentration tsis txaus Avian Influenza A Virus Pandemic Npaj thiab Kev Txhim Kho Tshuaj Tiv Thaiv kom ua rau lub cev tsis muaj zog. teb. Yog li ntawd, txawm tias qhov kev sim yooj yim ntawm kev ua tau zoo yuav siv sij hawm tsawg kawg ob peb lub hlis, thiab cov kws kho mob yuav saib xyuas kev nyab xeeb ntawm cov tshuaj tiv thaiv kev noj qab haus huv ntawm cov neeg tuaj yeem pab dawb rau ib xyoos.

Qhov thib ob, COVID-19 yog qhov xwm txheej uas ua rau tib neeg kev sim siab zoo li ua tsis tau zoo rau ntau tus.

Kev tuag los ntawm tus kab mob niaj hnub no yog kwv yees li ntawm ob peb feem pua, thiab tus nqi no yuav raug txo ntxiv sai li sai tau thaum nws pom tseeb tias pes tsawg tus neeg tau raug tus kab mob asymptomatically. Tab sis cov tshuaj tiv thaiv, yog tias nws tau tsim tam sim no, yuav tsum tau muab rau ntau lab tus tib neeg, thiab txawm tias cov kev mob tshwm sim me me tuaj yeem ua rau muaj pes tsawg tus kab mob thiab kev tuag piv rau tus kab mob nws tus kheej. Thiab tus kabmob tshiab no nyob deb ntawm "kev npau taws" txaus rau, hauv cov lus ntawm Rizvanov, "ua tiav pov tseg tag nrho cov kev xav txog kev nyab xeeb." Tus kws tshawb fawb ntseeg tias hauv qhov xwm txheej tam sim no, kev cais tawm yog qhov ua tau zoo tshaj plaws.

Txawm li cas los xij, raws li Karpova, tsis muaj qhov yuav tsum tau txhaj tshuaj tiv thaiv sai sai rau yav tom ntej. Nws piav qhia tias "Tsis tas yuav txhaj tshuaj tiv thaiv tib neeg thaum muaj kev sib kis, qhov no tsis ua raws li cov cai ntawm kev sib kis," nws piav qhia.

Galina Kozhevnikova, tus thawj coj ntawm Lub Tsev Haujlwm Saib Xyuas Kabmob Sib Kis ntawm RUDN University, pom zoo nrog nws. “Thaum muaj kev sib kis, tsis pom zoo txhaj tshuaj tiv thaiv txhua, txawm tias ib txwm ua, uas suav nrog hauv lub sijhawm txhaj tshuaj. Vim tias tsis muaj kev lees paub tias tus neeg tsis nyob hauv lub sijhawm incubation, thiab yog tias siv tshuaj tiv thaiv tam sim no, cov xwm txheej tsis zoo thiab txo cov tshuaj tiv thaiv kev ua haujlwm tau zoo, Kozhevnikova tau hais, teb cov lus nug N + 1.

Muaj cov xwm txheej, nws hais ntxiv, thaum txhaj tshuaj tiv thaiv xwm txheej ceev yog tsim nyog rau kev noj qab haus huv, hauv qhov xwm txheej thaum nws los txog rau txoj sia thiab tuag. Piv txwv li, thaum muaj tus kab mob anthrax tshwm sim hauv Sverdlovsk xyoo 1979, txhua tus tau txhaj tshuaj tiv thaiv, ntau txhiab tus neeg tau txhaj tshuaj sai sai, thiab xyoo 1959 hauv Moscow thaum muaj tus kab mob me me coj los ntawm Kokorekin, Alexei Alekseevich - "Wikipedia" los ntawm Is Nrias teb los ntawm tus kws kos duab Alexei Kokorekin.

"Tab sis tus mob coronavirus tsis yog zaj dab neeg zoo li no. Los ntawm qhov tshwm sim, peb pom tias tus kabmob kis no tau txhim kho raws li cov kev cai qub ntawm tus kabmob ua pa, "hais tias Kozhevnikova.

Yog li, cov neeg tsim tshuaj tiv thaiv ib txwm nyob hauv qhov xwm txheej tsis txaus ntseeg. Tsuav tsis muaj tus kab mob no, nws yuav luag tsis tuaj yeem tsim tshuaj tiv thaiv. Thaum tus kab mob no tshwm sim, nws hloov tawm tias nws yuav tsum tau ua ua ntej nag hmo. Thiab thaum nws thim rov qab, manufacturers poob lawv cov neeg siv khoom.

Txawm li cas los xij, yuav tsum tau txhaj tshuaj tiv thaiv. Qhov no tsis tau tshwm sim thaum muaj kev kis tus kabmob coronavirus yav dhau los - ob qho tib si MERS thiab SARS tau xaus sai dhau, thiab kev tshawb fawb poob nyiaj. Tab sis yog tias tsis muaj tus mob SARS hauv ntiaj teb txij li xyoo 2004, ces qhov kawg ntawm MERS tau rov qab mus rau xyoo 2019, thiab tsis muaj leej twg tuaj yeem lav tias qhov kev sib kis yuav tsis tshwm sim dua. Tsis tas li ntawd, tshuaj tiv thaiv kab mob yav dhau los tuaj yeem muab lub tswv yim zoo rau kev tsim cov tshuaj tiv thaiv yav tom ntej.

Karpova sau tseg tias txawm tias tom qab qhov kev sib kis ntawm COVID-19 ploj mus, lwm qhov tshwm sim tuaj yeem ua tau. Thiab qhov no, lub xeev yuav tsum tau npaj tshuaj tiv thaiv. Nws hais tias "Qhov no tsis yog hom tshuaj tiv thaiv uas txhua tus neeg yuav tau txhaj tshuaj zoo li tus mob khaub thuas," nws hais. "Tab sis thaum muaj xwm txheej ceev nrog tus kab mob tshiab, lub xeev yuav tsum muaj cov tshuaj tiv thaiv zoo li no, nrog rau kev sim ntsuas."
