We now know that BA.2 has an increased growth rate which can be seen in all regions in England. This will include analysing live samples of the new variant in our laboratories to investigate properties such as response to current vaccines. Based on the CDC's genomic surveillance, the BA.2 or stealth Omicron subvariant is responsible for most new SARS-CoV-2 infections in the U.S. BA.2 is a subvariant of the original SARS-CoV-2 Omicron variant (B.1.1.529), along with BA.1.1 and BA.3.

Whilst the impact of these variants is uncertain, the variant classification system aims to identify potential risk as early as possible. Experts in Kolkata say that BA.2 symptoms are mostly associated with abdomen and stomach instead of cough or shortness of breath. The proportion of test results displaying SGTF has been very low in recent months but an increase has been observed in the past week.
