I don't think you're being snarky. I feel we are having a good, stimulating, but respectful conversation. I am teachable. I proposed this questions/statement to learn from my fellow nursing community, that is all.
I am aware that coughing into my elbow is good practice. As is washing your hands thoroughly. However, if I work from home, and shelter in place like Washington state currently is ordered, then my spread risk is quite low. I feel that for healthy individuals, coughing in your elbow and washing your hands correctly and routinely, is the best way to go. Sick people should wear masks, as was always the expectation even before this pandemic.
