The quickly changing coronavirus has spawned yet another super contagious omicron mutant that’s worrying scientists as it gains ground in India and pops up in numerous other countries, including the United States.
Scientists say the variant — called BA.2.75 — may be able to spread rapidly and get around immunity from vaccines and previous infection. It’s unclear whether it could cause more serious disease than other omicron variants, including the globally prominent BA.5.
“It’s still really early on for us to draw too many conclusions,” said Matthew Binnicker, director of clinical virology at the Mayo Clinic in Rochester, Minnesota. “But it does look like, especially in India, the rates of transmission are showing kind of that exponential increase.” Whether it will outcompete BA.5, he said, is yet to be determined.
