The problem with this mentality is you may not be considering how viral load may correlate to clinical symptoms. Like you, I am beyond "containment." I fully expect I have or will contract the virus. Our hospital has two patients under investigation (1 ASA4, 1 ASA3). As anesthesiologists, we are right in the line of fire and would potentially receive very high viral loads from performing aerosolizing procedures (intubations) on the patients with the worst disease. Therefore, we must take every precaution imaginable to reduce how much virus gets into our system. Analogous to how our population is attempting to "flatten the curve," we must each individually flatten our own curves and keep our viral exposure below the thresholds of our immune response systems.
Please protect yourself and never intubate anyone without proper PPE (N95 or PAPR/CAPR). If your hospital runs out, don't be a hero.
