We have one advantage in the diagnosis of omicron: the S gene, which is one of the three genes that common PCR tests look for, is missing. That means that rather than having to wait for genomic testing, which takes quite a long time, we get a heads-up or an early warning on the PCR test. There is a sub-group with S-gene dropout, which means that the chances are that it could be omicron. Those patients could be warned and their samples can then be sent for full genomic testing. In Scotland, a retrospective review of recent PCR results looking for S-gene dropout has identified the nine patients with omicron. I assume that similar work is happening in the other nations across the UK. In contact tracing of the nine patients, there is no evidence of a connection to either COP26 or the South Africa rugby game, but tracking continues.
