I'm willing to bet that after this ends, that PPE protocols will be amended...and some flexibility is allowed for, provided it meets a crisis level

if you are a health care worker not in direct contact with a quarantined patient (of any disease),we know that bacteria and virus can be killed... ultra violet light, ethanol, heat, possibly microwave, etc, that destroys the sheath or capsule around the DNA/RNA virus strand, (encapsulated TB will be a different animal)the common practice of changing masks multiple times a day may have to be addressed... yes, it is better to have a new mask, but what if you come to work tomorrow and there is no mask?
