Personal protection equipment in the time of COVID-19

Personal protection equipment in the time of COVID-19

Health authorities are hamstrung here, because of a paucity of data. We still know far less about COVID viruses in general, and COVID-19 in particular, than we’d like. We know about how far they can travel, person to person, about how long they can survive on various surfaces and in the air, and we know sort of how they replicate. But we don’t know anything about their ability to confer immunity, or why they hit some parts of the population harder than others.
