omicron variantThis version of the coronavirus, which scientists call BA.2, is widely considered stealthier than the original version of omicron because particular genetic traits make it somewhat harder to detect. Danish scientists reported this week that preliminary information suggests it may be 1½ times more contagious than the original variant.
"Preliminary calculations indicate that BA.2 is one and a half times more contagious than BA.1," the original omicron, the institute's Dr. Tyra Grove Krause said in a press release earlier this week. If it is more contagious, "it may mean that the wave of infections will be higher and will extend further into February compared to the previous projections."
For now, the original omicron BA.1 and its descendant BA.2 are considered subsets of omicron. But global health leaders could give it its own Greek letter name if it is deemed a globally significant "variant of concern." Doctors also don’t yet know for sure if someone who’s already had COVID-19 caused by omicron can be sickened again by BA.2. But they’re hopeful, especially that a prior omicron infection might lessen the severity if that happens.
