I don't want to sound alarmist, but ER docs tend to be 30-40-something's in fantastic health. I'm curious if there is cytokine storm involvement that further degrades lung capacity. Finally, there's a real risk they may never be well enough to return to duty after 6-8 weeks due to severe (and permanent) lung injury. ER docs, respiratory therapists and perfusionists don't grow on trees... taking just one out is a huge minus for a crashing tsunami of critical cases poised to break simultaneously.
