The New York State Department of Health today announced the emergence of two Omicron subvariants in New York State, BA.2.12 and BA.2.12.1. Both variants are sub-lineages of BA.2, which now accounts for 80.6% of COVID-19 infections in New York. The subvariants have been estimated to have a 23% – 27% growth advantage above the original BA.2 variant.
"We are alerting the public to two Omicron subvariants, newly emerged and rapidly spreading in upstate New York, so New Yorkers can act swiftly," said State Health Commissioner Dr. Mary T. Bassett. "While these subvariants are new, the tools to combat them are not. These tools will work if we each use them: get fully vaccinated and boosted, test following exposure, symptoms, or travel, consider wearing a mask in public indoor spaces, and consult with your healthcare provider about treatment if you test positive. I thank the Department's scientists for leading this effort and those contributing to this work throughout New York and around the world."
