Mutsauko mutsva uye unotapukira uye une ngozi weOmicron, parizvino unonzi Omicron BA.2 subtype musiyano, wabuda uyo wakakoshawo asi usingakurukurwe pane mamiriro eUkraine. (Chinyorwa cheMupepeti: Maererano neWHO, Omicron strain inosanganisira b.1.1.529 spectrum uye vazukuru vayo ba.1, ba.1.1, ba.2 uye ba.3. ba.1 ichiri kuverengera huwandu hwehutachiona, asi ba.2 zvirwere zviri kuwedzera.)
BUPA inotenda kuti kuwedzera kusagadzikana mumisika yepasirese mumazuva mashoma apfuura kuri kukonzerwa nekudzikira kwemamiriro ezvinhu muUkraine, uye chimwe chikonzero ndeye musiyano mutsva weOmicron, mutsva wehutachiona unofungidzirwa nesangano iri kuti uri kukwira munjodzi uye ane macro kukanganisa kwehupfumi hwepasi rose kungave kwakatonyanya kukosha kupfuura mamiriro eUkraine.
Zvinoenderana nezvichangobva kuwanikwa kubva kuYunivhesiti yeTokyo kuJapan, iyo BA.2 subtype musiyano haingopararira nekukurumidza kana ichienzaniswa neiyo iripo zvino COVID-19, Omicron BA.1, asi inogona kukonzera kurwara kwakanyanya uye inoita kunge inokwanisa kukanganisa. zvimwe zvezvombo zvakakosha zvatinazvo kurwisa COVID-19.
Vatsvakurudzi vakatapurira hamster neBA.2 uye BA.1 strains, maererano, uye vakawana kuti avo vane utachiona hweBA.2 vairwara uye vane kukuvara kwakanyanya kwemapapu. Vatsvakurudzi vakawana kuti BA.2 inogona kutonyenyeredza mamwe masoja ekudzivirira chirwere anogadzirwa nejekiseni uye haashingirwe nemimwe mishonga yekurapa.
Vatsvakurudzi vekuedza vakati, "Kuedza kweNeutralization kunoratidza kuti kudzivirirwa kwekudzivirira kwejekiseni hakushande paBA.2 sezvakunoita BA.1."
Nyaya dzeBA.2 variant virus dzakataurwa munyika dzakawanda, uye World Health Organization inofungidzira kuti BA.2 inenge 30 muzana inotapukira kupfuura yezvino BA.1, iyo yakawanikwa munyika 74 uye 47 US states.
Iyi subvariant virus inobata 90% yezviitiko zvitsva zvitsva muDenmark. Denmark yakaona ichangoburwazve muhuwandu hwenyaya dzakafa nekuda kwehutachiona neCOVID-19.
Zvakawanikwa kubva kuYunivhesiti yeTokyo kuJapan uye zviri kuitika kuDenmark zvakazivisa dzimwe nyanzvi dzepasi rose.
Epidemiologist Dr. Eric Feigl-Ding akatora ku Twitter kuti ashevedze kudiwa kwe WHO (World Health Organization) kuti izivise mutsva mutsva weOmicron BA.2 chikonzero chekunetseka.
Maria Van Kerkhove, WHO's technical lead for the new coronavirus, akataurawo kuti BA.2 yatove mutsauko mutsva weOmicron.
Vatsvakurudzi vakadaro.
"Kunyange zvazvo BA.2 ichionekwa sechinhu chitsva chemutant cheOmicron, kutevedzana kwayo kwegenome kwakasiyana zvikuru neBA.1, zvichiratidza kuti BA.2 ine virological profile yakasiyana neBA.1."
BA.1 uye BA.2 vane zvakawanda zvekuchinja, kunyanya muzvikamu zvakakosha zveprotein yeviral stinger. Jeremy Luban, chiremba wehutachiona paYunivhesiti yeMassachusetts Medical School, akati BA.2 ine boka rose rekuchinja kutsva kusina munhu akamboedza.
Mads Albertsen, a bioinformatician paAalborg University kuDenmark, akati kupararira kuri kuramba kuchiwedzera kweBA.2 munyika dzakati wandei kunoratidza kuti ine mukana wekukura pane zvimwe zvakasiyana, kusanganisira mamwe masubtype akasiyana eOmicron, akadai seasinganyanyozivikanwa anozivikanwa seBA. 3.
Chidzidzo chemhuri dzinopfuura 8,000 dzeDanish dzakabatwa neomicron dzinoratidza kuti kuwedzera kwehuwandu hwehutachiona hweBA.2 hunokonzerwa nezvikonzero zvakasiyana-siyana. Vatsvakurudzi, kusanganisira Troels Lillebaek, chiremba wechirwere chechirwere uye sachigaro weDanish Committee for Risk Assessment of COVID-19 Variants, vakawana kuti vanhu vasina kubayiwa, vakabayiwa nhomba mbiri uye vakabaiwa nhomba yebooster-vazhinji vanogona kutapukirwa neBA.2 kupfuura BA.1 utachiona.
Asi Lillebaek akati BA.2 inogona kuunza dambudziko rakakura apo mitengo yekudzivirira yakadzikira. Kubudirira kwekukura kwekusiyana uku pamusoro peBA.1 kunoreva kuti inogona kuwedzera nguva yepamusoro yehutachiona hweomicron, nokudaro kuwedzera mikana yehutachiona kune vakwegura uye vamwe vanhu vari pangozi yehosha yakakomba.
Asi pane chivara chakajeka: masoja ekudzivirira chirwere ari muropa revanhu vachangobva kutapukirwa neomicron virus anoitawo seanopa dziviriro kuBA.2, kunyanya kana vakabayiwawo.
Izvi zvinosimudza pfungwa yakakosha, anodaro University of Washington School of Medicine virologist Deborah Fuller, kuti nepo BA.2 ichiita seine hutachiona uye pathogenic kupfuura Omicron, inogona kusazoguma yakonzera kuwedzera kunoparadza kwehutachiona hweCOVID-19.
Hutachiona hwakakosha, akadaro, asi ndizvo zvatiri isu sevanokwanisa kugona. Tichiri munhangemutange yekurwisa hutachiona, uye haisi nguva yekuti nharaunda dzisimudze mutemo wemasiki.
