Experts are also calling BA.2 a 'stealth omicron,' as there's a key difference in its genetic sequence that makes it harder to track.
SAN FRANCISCO -- There's a new"subvariant" of the omicron variant that's been spreading across Europe and the U.S.
"In Denmark where it's sort of taken over it looks like it's 1 and a half times more infectious than the original omicron which was more infectious than delta," said Dr. Deepak Srivastava, President of the Gladstone Institutes. UCSF Professor Nevan Krogan is the Director of Quantitative Biosciences Institute. He broke down BA.2 in comparison to the original omicron strain.
Professor Krogan's team identify the section where the majority of transmission is forming within the BA.2 variant.How concerned should you be of new omicron subvariant BA.2 if you're vaccinated or boosted?
