x***l 发帖数: 315 | 1 Why masks are again advised for everyone indoors
For a large part of the U.S., that’s the latest advice from the Centers for
Disease Control and Prevention. The CDC this week revisited and revised its
guidance for wearing masks indoors to stop the spread of coronavirus.
The change comes two months after the agency eased its mask advice,
declaring that fully vaccinated people no longer had to cover up at indoor
public places. Since then, the agency also said vaccinated adults and teens
no longer needed to wear them at summer camps and schools. |
