Less common symptoms include loss of taste and smell and shortness of breath. Anosmia and ageusia appear, anecdotally, to be less common with XBB. Experts don’t expect ageusia and anosmia to make a comeback just yet. “Since XBB is part of the omicron group, I expect that loss of taste and smell will not be common, but I have not seen data yet,” said Dr. Thomas Campbell, a professor in the department of infectious disease at the University of Colorado Anschutz Medical Campus.
