Kusiyanasiyana kwatsopano komanso koopsa kwa Omicron, komwe kumatchedwa Omicron BA.2 subtype kusiyana, kwatulukira komwe kulinso kofunikira koma sikukambidwa mochepera kuposa momwe zilili ku Ukraine. (Zolemba mkonzi: Malinga ndi WHO, mtundu wa Omicron umaphatikizapo mawonekedwe a b.1.1.529 ndi mbadwa zake ba.1, ba.1.1, ba.2 ndi ba.3. ba.1 akadali ndi matenda ambiri, koma matenda a ba.2 akuchulukirachulukira.)
BUPA ikukhulupirira kuti kusakhazikika kwina m'misika yapadziko lonse lapansi m'masiku angapo apitawa ndi chifukwa chakuwonongeka kwa zinthu ku Ukraine, ndipo chifukwa china ndi mtundu watsopano wa Omicron, mtundu watsopano wa kachilomboka womwe bungweli likukhulupirira kuti likukwera pachiwopsezo komanso lomwe. kukhudza kwambiri chuma padziko lonse lapansi kungakhale kofunikira kwambiri kuposa momwe zilili ku Ukraine.
Malinga ndi zomwe zapezedwa posachedwa kuchokera ku University of Tokyo ku Japan, mtundu wa BA.2 subtype sikuti umangofalikira mwachangu poyerekeza ndi COVID-19 yomwe yafala pano, Omicron BA.1, komanso imatha kuyambitsa matenda oopsa komanso kuoneka kuti ikhoza kulepheretsa. zida zina zazikulu zomwe tili nazo polimbana ndi COVID-19.
Ofufuzawo adayambitsa tizilombo toyambitsa matenda a BA.2 ndi BA.1, motsatira, ndipo adapeza kuti omwe ali ndi BA.2 anali odwala kwambiri ndipo anali ndi vuto lalikulu la mapapu. Ofufuzawo adapeza kuti BA.2 imatha kuzembetsa ma antibodies ena opangidwa ndi katemerayo ndipo imagonjetsedwa ndi mankhwala ena ochizira.
Ofufuza a kuyesako anati, "Kuyesa kwa Neutralization kumasonyeza kuti chitetezo chopangidwa ndi katemera sichigwira ntchito mofanana ndi BA.2 monga momwe chimachitira ndi BA.1."
Milandu ya BA.2 variant virus yadziwika m'maiko ambiri, ndipo World Health Organisation ikuyerekeza kuti BA.2 ndi pafupifupi 30 peresenti yopatsirana kuposa BA.1 yamakono, yomwe yapezeka m'maiko 74 ndi 47 US states.
Kachilombo kakang'ono kameneka kamakhala ndi 90% ya milandu yatsopano ku Denmark. Denmark yawona kuchuluka kwaposachedwa kwa chiwerengero cha anthu omwe amwalira chifukwa cha matenda a COVID-19.
Zomwe apeza kuchokera ku yunivesite ya Tokyo ku Japan komanso zomwe zikuchitika ku Denmark zachenjeza akatswiri ena apadziko lonse lapansi.
Katswiri wa matenda a Epidemiologist Dr. Eric Feigl-Ding adapita ku Twitter kuti adziwe kufunikira kwa WHO (World Health Organization) kuti alengeze kusiyana kwatsopano kwa Omicron BA.2 chifukwa chodetsa nkhawa.
Maria Van Kerkhove, mtsogoleri waukadaulo wa WHO pa coronavirus yatsopano, adatinso BA.2 ndi mtundu watsopano wa Omicron.
Ofufuzawo anatero.
"Ngakhale kuti BA.2 imatengedwa kuti ndi mtundu watsopano wosinthika wa Omicron, ndondomeko yake ya genome ndi yosiyana kwambiri ndi BA.1, kutanthauza kuti BA.2 ili ndi mbiri ya virological yosiyana ndi BA.1."
BA.1 ndi BA.2 ali ndi masinthidwe ambiri, makamaka m'magawo ofunikira a mapuloteni a mbola. Jeremy Luban, katswiri wa ma virus ku University of Massachusetts Medical School, adati BA.2 ili ndi masinthidwe ambiri atsopano omwe palibe amene adawayesa.
Mads Albertsen, katswiri wa sayansi ya zamoyo ku yunivesite ya Aalborg ku Denmark, anati kufalikira kwa BA.2 m'mayiko angapo kukusonyeza kuti ili ndi mwayi wokulirapo kusiyana ndi mitundu ina, kuphatikizapo mitundu ina ya Omicron, monga mtundu wosatchuka kwambiri wotchedwa BA. 3.
Kafukufuku wa mabanja oposa 8,000 a ku Danish omwe ali ndi omicron amasonyeza kuti kuchuluka kwa matenda a BA.2 kumachitika chifukwa cha zinthu zosiyanasiyana. Ofufuza, kuphatikiza Troels Lillebaek, katswiri wa miliri komanso wapampando wa Danish Committee for Risk Assessment of COVID-19 Variants, adapeza kuti anthu omwe sanatemeledwe, katemera wapawiri komanso omwe ali ndi chilimbikitso onse amatha kutenga kachilombo ka BA.2 kuposa BA.1 matenda.
Koma Lillebaek adati BA.2 ikhoza kukhala ndi vuto lalikulu pomwe mitengo ya katemera imakhala yotsika. Ubwino wa kukula kwa kusiyana kumeneku pa BA.1 kumatanthauza kuti ikhoza kutalikitsa chiwopsezo cha matenda a omicron, motero kuonjezera mwayi wa matenda kwa okalamba ndi anthu ena omwe ali pachiopsezo chachikulu cha matenda aakulu.
Koma pali malo owala: ma antibodies m'magazi a anthu omwe atenga kachilombo ka omicron posachedwapa amawonekeranso kuti amapereka chitetezo ku BA.2, makamaka ngati adalandiranso katemera.
Izi zimadzutsa mfundo yofunika, akutero katswiri wa zachipatala ku University of Washington School of Medicine Deborah Fuller, kuti ngakhale BA.2 ikuwoneka kuti ndi yopatsirana komanso yapathogenic kuposa Omicron, sitha kupangitsa kuti matenda a COVID-19 awonongeke.
Kachilomboka ndi kofunikira, adatero, koma momwemonso ndife omwe tingathe kukhala nawo. Tidakali pa mpikisano wolimbana ndi kachilomboka, ndipo sinakwane nthawi yoti madera akweze lamulo la chigoba.
