What to Know About Omicron

Australia’s Queensland state has found a new omicron lineage in a traveler who arrived from South Africa, health authorities said Wednesday. 

The new lineage has about half the gene variations of the original and can’t be detected with typical screening, the state’s acting chief health officer Peter Aitken told reporters. It was found in a traveler who had arrived from South Africa and tested positive for the coronavirus on Saturday, he said.
