What Is BA.2, the So-Called ‘Stealth Omicron’ Variant?

Thomas A. Russo, MD, SUNY Distinguished Professor of medicine and chief of the Division of Infectious Diseases in the Jacobs School was quoted in Prevention in an article on the Stealth Omicron variant. “Omicron has branched into three lineages, explains Russo, “BA.1, BA.2, and BA.3. Because BA.1 has spread the most rapidly around the world, it’s gotten the most attention, Dr. Russo says—but BA.2 is starting to gain steam, too.” The article was carried by Yahoo! Life.
