And the large number of mild cases might just reflect who is getting infected. Due to a deletion in the S, or spike, gene, omicron variant samples will not test positive for that particular part of the virus, producing what scientists are referring to as S gene dropout. Simultaneous checks for, You still get a positive test, but you dont see the S gene because a mutation means that part of the test doesnt work, explained, , a postdoctoral researcher at the University of Bern and a co-developer of the virus-tracking site. I am a bot, and this action was performed automatically.
