A new omicron variant (BA.2) resembles the original lineage but differs in many ways, especially because it is indistinguishable from other variants using standard PCR techniques earning it’s title as the ‘stealth variant’. So far 7 cases have been identified from South Africa, Australia and Canada. Although it is too early to comment on it’s behavior, BA.2 is genetically different enough for it to have some potentially unique features. Current PCR tests are still able to detect the new variant, and experts do not see a reason for concern yet.
