It's official the Omicron COVID-19 variant has arrived in Queensland. We hear of viral variants such as delta and lambda, a nomenclature invoked as scientists realized the unintended bias (and sometimes persecution) associated with the geographic labeling of variants. Since many are using home tests that are not reported through public health or are not testing at all, the official case counts underestimate the actual prevalence of COVID-19.
