To Mask or Not To Mask?

[taiwan_girl]

Of course, for everything I show below, someone will post something that contradicts it. But, I think one of best arguments for masks would come from our medical people here (you included Jolly). As you guys have pointed out previously, if you go into an operating room, it is standard to wear a mask? Are they doing it for fashion? LOL I dont think so. To prevent spread of disease? Ding ding!!!!

You Tube Video above. At about 4:30, they do a demonstration of a man with/without mask talking/singing/coughing/sneezing into a petri dish and monitoring the growing of bacteria. Rest of the video is interesting also.

Oxford University study
Methods
An online assessment that included demographic, clinical, and exposure information and a blood sample was collected from 20,614 participants out of ~43,000 total employees at Beaumont Health, which includes eight hospitals distributed across the Detroit metropolitan area in southeast Michigan. The presence of anti-SARS-CoV-2 IgG was determined using the EUROIMMUN assay.
Results
A total of 1,818 (8.8%) participants were seropositive between April 13 and May 28, 2020. Among the seropositive individuals, 44% reported that they were asymptomatic during the month prior to blood collection. Healthcare roles such as phlebotomy, respiratory therapy, and nursing/nursing support exhibited significantly higher seropositivity. Among participants reporting direct exposure to a COVID-19 positive individual, those wearing an N95/PAPR mask had a significantly lower seropositivity rate (10.2%) compared to surgical/other masks (13.1%) or no mask (17.5%).
Conclusions
Direct contact with COVID-19 patients increased the likelihood of seropositivity among employees but study participants who wore a mask during COVID-19 exposures were less likely to be seropositive. Additionally, a large proportion of seropositive employees self-reported as asymptomatic. (Funded by Beaumont Health and by major donors through the Beaumont Health Foundation)

Actually, there have been very few studies demonstrating the efficacy of masks in preventing infection in the patient. If anything, they protect the team standing at the table. In some countries, like Great Britain, those not standing at the table (circulating nurse, anesthesiologist, are not masked.

Those studies, in addition, looked at the incidence of bacterial, not viral, infection.

All that said, I remain in the "it wouldn't hurt" school. It's a minor imposition, and is of little expense. These days, even if it helps a little it's worth the minor effort on my part.

N95 masks, last time I looked are still difficult to come by, by the way.

I agree with you 1000% on this. It seems like a minor thing to do, and as part of the overall strategy to beat the COVID, a smart thing.

I have no idea who this guy is, either:

@george-k seems classic correlation vs causation confusion.

I know. But if you dive deeper, you'll see that places with mandates really fared no better. What else could be the factors, he doesn't get into.
