@RedLittleladyin @tammyischatty @DrLeanaWen ER docs are not only wearing an mask. Standards for ventilation in medical facilities are higher. Medical employers provide the masks and fit testing (or papr if needed). Patients screened and masked when they come through the door before the doc ever sees them. Not comparable.
@RedLittleladyin@tammyischatty@DrLeanaWen ER医生不仅戴着口罩。医疗设施的通风标准更高。医疗雇主提供口罩和健康测试（或papr，如果需要）。当患者在医生看到他们之前通过门时，他们会进行筛查并戴上口罩。不可比。
