In February, New York State Health officials identified a small number of new Covid cases related to a new, even more infectious subvariant of Omicron BA.2. Dubbed BA.2.12.1, it made up only 3% of all new cases in the state for that month. Figures released today by the CDC indicate that in the past eight weeks BA.2.12.1 has not only outcompeted BA.2 in terms of growth, but it has now become the dominant variant in the region made up of New York, New Jersey and Connecticut. The CDC data indicates that BA.12.2 now accounts for 58% of new cases in the region. In New York state, its share is much higher.
