Hadda XBB 1.5 Kala duwanaanshaha ayaa ku waalan adduunka dhexdiisa. Qaar ka mid ah macmiilku wuxuu ka qabaa in tijaabadayada xawaaraha-19-ka-daadashada ee Antigen ay ku ogaan karaan kala duwanaantaas ama ma aha.

Spikeprotein oo ka jira dusha sare ee 'Coronavirus' oo si fudud loo beddelo sida Alpha kala duwanaanshaha (BMA.7), Babta Kala-duwanaanta (BM.517), Delta varta (B.1.529), Kala-duwanaanta Omicron (XBBRON) iyo wixii la mid ah.
Nucleocdi-ga fayras nucleocid wuxuu ka kooban yahay ka kooban borotiinka nucleocdid (n borotiinka gaaban) iyo rna. Borotiinka n waa mid deggan, saamiga ugu weyn ee borotiinnada dhillooyinka fayraska iyo dareenka sare ee ogaanshaha.
Iyada oo ku saleysan astaamaha n borotiin, monoclonal antibody of n borotiinka n
Coronavirus waxaa lagu soo xushay horumarka iyo qaabeynta badeecadeena oo loo magacaabay "SARS-Covid Covil-2 Dahabka Antiden)" kaas oo loogu talagalay ogaanshaha tayada ee SARS-2 ee ka mid ah suumanka Nasal Swar ee ka dhacaya cudurka vitro Terotiin.
Taasi waa in la yiraahdo, hadda ee hadda jirta ee xaraashka ah ee hadda jira ee Spikeprotein
