Thank you for your work with patients - anyone working in the health field has chosen an important and meaningful career and has my respect.You're clearly not the only one.
All I can tell you is this. When going in to evaluate someone that has actual respiratory illness (cough/fever) and possible/suspected COVID, I'm not wearing an N95 mask. That's in an enclosed space with likely infection and active coughing and right next to them (< 6 ft). Simple surgical mask and eye protection along with gown and gloves. And it's not due to lack of N95 where I am as I have it available.
And it's certainly not because I'm taking COVID lightly. If medical providers aren't even using N95 masks during actual interactions with this disease, then not sure how else you'd be convinced that you just don't need it walking down the aisle of a grocery store, even if someone just sneezed or coughed near you (i.e. > 6 ft away). If you're that concerned about someone sneezing near you, just walk in the other direction for a few minutes (even though it's not necessary).
One good thing that will come out of this is that for the rest of our lives, everyone experiencing this event right now will have a heightened respect and appreciation for medical professionals.
In regards to mask guidance and C19, we've already seen steadily evolving guidance from the Federal Government and from the CDC, and I'm quite sure that guidance will continue to change as we go forward and learn more.
Sneezes in particular are my greatest concern; some people (e.g. my wife ) sneeze suddenly and unexpectedly.
While out in public, you often don't know if someone has recently sneezed in the space you are now occupying, e.g. a grocery store aisle.
How much risk is there in walking down an aisle 30 seconds (or 60, or 120) after someone sneezed in that space?... for me, the answer is: I don't know, but I do know it's not zero and it may well be a higher risk than people currently realize.
This is literally the first search result I got when I googled Sneeze Aerosol : https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4676262/
The abstract of their results are below, I highlighted the parts that indicate to me that it is not unreasonable to wear an N95 mask while shopping in a supermarket during a pandemic.
The question of whether influenza is transmitted to a significant degree by aerosols remains controversial, in part, because little is known about the quantity and size of potentially infectious airborne particles produced by people with influenza. In this study, the size and amount of aerosol particles produced by nine subjects during coughing were measured while they had influenza and after they had recovered, using a laser aerosol particle spectrometer with a size range of 0.35 to 10 μm. Individuals with influenza produce a significantly greater volume of aerosol when ill compared with afterward (p = 0.0143). When the patients had influenza, their average cough aerosol volume was 38.3 picoliters (pL) of particles per cough (SD 43.7); after patients recovered, the average volume was 26.4 pL per cough (SD 45.6). The number of particles produced per cough was also higher when subjects had influenza (average 75,400 particles/cough, SD 97,300) compared with afterward (average 52,200, SD 98,600), although the difference did not reach statistical significance (p = 0.1042). The average number of particles expelled per cough varied widely from patient to patient, ranging from 900 to 302,200 particles/cough while subjects had influenza and 1100 to 308,600 particles/cough after recovery. When the subjects had influenza, an average of 63% of each subject's cough aerosol particle volume in the detection range was in the respirable size fraction (SD 22%), indicating that these particles could reach the alveolar region of the lungs if inhaled by another person. This enhancement in aerosol generation during illness may play an important role in influenza transmission and suggests that a better understanding of this phenomenon is needed to predict the production and dissemination of influenza-laden aerosols by people infected with this virus.
