Scientists Are Learning More About ‘Stealth Omicron”
The coronavirus mutant widely known as “stealth omicron” is now causing more than a third of new omicron cases around the world, but scientists still don’t know how it could affect the future of the pandemic.
Researchers are slowly revealing clues about the strain, a descendant of omicron known as BA.2, while warily watching it become ever more prevalent.
“We’re all keeping an eye on BA.2 just because it has done particularly well in some parts of the world,” including parts of Asia, Africa and Europe, said Dr. Wesley Long, a pathologist at Houston Methodist in Texas.
