Ubu ubwoko bwa XBB 1.5 burakabije ku isi. Hari abakiriya bakeka niba ikizamini cyacu cya antigen ya covid-19 gishobora kubona ubu bwoko cyangwa kitabubona.

Poroteyine ya Spike glycoprotein ibaho ku buso bwa coronavirus nshya kandi ihinduka byoroshye nka Alpha variant (B.1.1.7), Beta variant (B.1.351), Gamma variant (P.1), Delta variant (B.1.617), Omicron variant (B.1.1.529), Omicron variant (XBB1.5) n'ibindi.
Nucleocapsid ya virusi igizwe na poroteyine ya nucleocapsid (poroteyine ya N mu magambo ahinnye) na RNA. Poroteyine ya N irahamye, niyo ifite poroteyine nyinshi mu miterere ya virusi kandi ifite ubushobozi bwo kuyimenya cyane.
Hashingiwe ku miterere ya poroteyine ya N, antibodi ya monoclonal ya poroteyine ya N irwanya urushya
Coronavirus yatoranyijwe mu gutegura no gushushanya ibicuruzwa byacu byitwa "SARS-CoV-2 Antigen Rapid Test (Colloidal Gold)" bigamije gupima neza Antigen ya SARS-CoV-2 mu dusabo tw’izuru binyuze mu gupima poroteyine ya N.
Ni ukuvuga ko ubwoko bwa glycoprotein mutant buboneka muri iki gihe burimo XBB1.5 ntacyo buhindura ku bisubizo by'ikizamini.
