#Arcturus aka XBB.1.16 and its progeny XBB.1.31
After reading the #TACT newsletter on #COVID, my attention was drawn to one of the mutations of #SARS-CoV-2, in #Orf9b. Both variants share it.
Indeed, SARS-CoV-2 not only suppresses the immune system but in the most severe cases it over-activates it with the famous "cytokine storm". And the new mutation that shares these two variants is potentially on the "elastic" mechanism that triggers the cytokine storm.
