‘Stealth’ Variant No Cause for Alarm, but Could Slow Case Decline
The New York Times
A mutated version of the Omicron variant could slow the steep decline in cases, but it is not likely to change the overall course of the pandemic, scientists said.
In recent days, headlines about a “stealth” Omicron variant have conjured the notion that a villainous new form of the coronavirus is secretly creating a disastrous new wave of Covid.
That scenario is highly unlikely, scientists say. But the new variant, which goes by the scientific name BA.2 and is one of three branches of the Omicron viral family, could drag out the Omicron surge in much of the world.
So far, BA.2 doesn’t appear to cause more severe disease, and vaccines are just as effective against it as they are against other forms of Omicron. But it does show signs of spreading more readily.
