The big news today—the one that sent oil prices and stock markets plummeting—is that there is a new variant of COVID emerging in South Africa called. It’s been christened the “omicron” variant. Currently, it’s hard to tell if it’s really something to worry about or if it’s a variation on the theme. It’s enough to know that world governments are reacting as if it’s Spring 2020 all over again, plus more pressure for vaccines, all of which is ironic considering there’s no evidence that anything we did last year or this year helped stop COVID’s rampage.
An article in the San Francisco Chronicle has a mixture of fact and opinion that seems representative of the whole omicron phenomenon. First, the known facts:
The variant was discovered in South Africa, when cases suddenly spiked from an average of about 200 a day to 2,465 on Thursday. Scientists studying samples of the virus to try to explain the outbreak discovered the variant. That doesn’t necessarily mean the variant originated in South Africa, which has among the world’s best viral surveillance systems and may simply have been the first country to identify it.

Omicron has many more mutations than the currently world-dominant delta variant — more than 30 on the spike protein alone, which is considered key to the virus’ ability to infect human cells. The large number of mutations has scientists concerned that omicron could be more infectious than delta, and possibly able to evade immunity generated by previous infections or vaccines.
The WHO wrote in a report on the variant that preliminary evidence suggests that omicron might have “increased risk of reinfection.” Among omicron’s many mutations are sequences associated with increased infectiousness and reduced vaccine effectiveness.

Scientists still don’t know how omicron matches up with delta — a variant so transmissible that it essentially wiped out other variants of concern like alpha and beta. In the United States, delta still makes up 99% of cases that undergo genomic sequencing.
