Can someone explain for me please?
I understand Omicron is more transmissible than Alpha or Delta, so obviously there will be more people infected with O than A or D at any one time.
BUT how do the original A & D strains disappear?
I keep reading stuff suggesting Omicron may be the virus becoming less dangerous (because less severe) but given that people who have had O can still catch A or D (or the reverse) isn't the same threat we had of A or D still there?

What slang do you remember school teachers using?
