@BestinthePNW_ @D28EquityNow @drlucymcbride @kprather88 That's exactly why universal masking is more effective. Even imperfect use (within reason, chin masks don't count) of a surgical masks is going to reduce circulating particles in the air. Some exhaled air does go through the mask and get filtered.
@BestInPNW_@d28 equityNow@drlucymcbride@kprather88这正是通用掩蔽更有效的原因。即使不完美地使用外科口罩（在合理范围内，下巴口罩不算在内），也会减少空气中的循环颗粒物。一些呼出的空气确实会通过口罩过滤。
