@billcar09565665 @DrEricDing I see people wearing KN95s and N95s both correctly and incorrectly, so it isn't a matter of "never", it is "some" and moving that needle can help mitigate the impact of this surge and any potential future surges.
@billcar09565665@drericing我看到人们正确和不正确地佩戴了KN95和N95，所以这不是“从不”的问题，而是“一些”的问题，移动针头有助于减轻这次激增和未来任何潜在的激增的影响。
