Interesting regards masks, thanks. All I have is a "professional" dust mask I used at work, rather over the top and I would get some very strange looks! Something as simple as a scarf over mouth and nose would be better than nothing if the supermarket was too busy. I will probably leave it for a few days hopefully soon all the hoarders freezers and cupboards will be full and shopping will return to a semblance of normality.
 
Regarding face masks and respirators. You should be clean shaven for them to work as intended. Not much of a seal if the mask or respirator is sitting up atop beard or facial hair, and they will not protect you as designed etc. Something to take note of for those that may want to use them. Keep shaved.
 
At about 14:14 on this video Rishi Desai ( Former Center for Disease Control and Prevention Epidemic Intelligence Officer & Chief Medical Officer at Osmosi) explains why wearing a mask is helpful.

With this school of thought, could the UK have been onto something? Nip it in the bud?
 
I shaved my beard last week.

I guess I am lucky in a way. Last year my wife started Chemotherapy for cancer. I ordered several boxes of 99.5% bacterial filtration face masks. I still have some left over.

Last night I remembered a "Bug-Out" box I set up 20 years ago. I opened it up to find three boxes of N95 masks. I will give one box to a friend of mine and keep the rest for myself and my wife.

I also have a respirator with filters for painting. I am not sure how effective the filters would be against the virus, but I suspect it is better than nothing.

I have only seen four or five people with masks on besides myself in the past three times I went out to shop.

I don't expect to shop again for at least two or three weeks. Longer if it gets real deep. We hit 550 confirmed cases in TN today.

For comparison, TN is roughly the same size and population as Austria.

Well the UK isn't doing much of anything are they? Apparently, McDonald's has shut down all the restaurants in the UK.

I also have a respirator with filters for painting. I am not sure how effective the filters would be against the virus, but I suspect it is better than nothing.

Probably a lot better than a regular paper mask. Just not as convenient.

Facial Hair Guide for Masks

I thought I was the only one who shaved off the beard. Kept a goatee but the CDC calls it a circle beard. Who am I to question the CDC??? Looking at it I guess I'll have to cut some more off.... 🙁

I've uploaded a facial hair/mask guide from the CDC. I'd like to point out the Zappa. The man has left his mark! I had tickets to see Dweezil Zappa perform Hot Rats (Frank's best LP) this month and, of course, it's cancelled.

Yesterday I went out with my wife and son grocery shopping - we hit 3 stores; Groc Out, Walma and Winko. Saw only a few with masks on, we were wearing bandannas and I had the same balaclava / safery glasses getup I used last week.

These were used only to shield an inadvertant face-touch. One person I actually witnessed fiddling with the face mask - the exact thing they said wearing one tends to make you do. Which is dangerous...

I obtained and pushed the cart, while my wife and son "picked" making sure to touch nothing else. When a refrigerated case needed to be opened, I did so. I was wearing thin knit gloves. I also operated the self serve checkout kiosk, which did not work with the glove on.

I carried a spray bottle of ~70% isopropyl, dilluted down from 90%. After getting through the checkout, I hosed down my index finger real good and put the glove back on to push the cart out to the lot. They took the bagged groceries out of the cart and after sending it back to the return, I removed the gloves, tossed them into the back of the car, then hosed down my hands real good with the alcohol spray, rubbing them together.

leaving our face gear in place, off to the next store, rinse and repeat.

I read on line "disinfectants with 62-71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite (bleach) can "efficiently" inactivate coronaviruses within a minute, according to the study". I'm hoping my choice of spray bottle content was effective.

Also "4 teaspoons of bleach per quart of water" (I've always made mine skin-melting, sprayer mechanism destroying strong for household surface cleaning. Whatever the pink stuff is that grows in the shower doesnt stand a chance.) is a formula given in the same article. I havent tried it, but will consider as an alternative to the alcohol based spray - maybe doesnt smell so bad at that concentration.

Perhaps the new normal is you dont leave home without your spray bottle and simply clean as you go through whatever you need to make physical contact with - before making contact. "Still want to shake hands? Let's do a little spray first. I thought you'd change your mind..."

I would think masks would be effective for not conveying the disease agent into the air - by cough or sneeze - from someone who's actually infected, but doesnt know it yet. Most people in the stores werent wearing masks, I assume under the guise of "How was I supposed to know?" Perhaps the new normal of decency is to wear something covering nose and mouth to prevent accidently blasting your nasal ejections out into the air - unless you're tested +, gone through the required isolation period and deemed recovered.

I've also been wondering what something like chlorine gas would do to the life of a corona virus; if it's on something like a shoe. Thinking sealed container for shoes; introduce a little chlorine gas (a little bleach + vinnegar in a tiny cup?) and after overnight - everything dead, guaranteed. Currently I just leave those shoes out in the garage for a week - and hope any virus I picked up on them just dies in that time. (Of course, hand washing is the next step after shoe and clothes removal)

I'm sure I still need to improve my practices and am definitely interested in reliable head gear and disinfectant formulas for such necessary goings out as "shopping". Perhaps the new normal will be you dont go shopping, you order on-line and put everything delivered through the overnight gas chamber. Yum! But that 31 yr old nurse experience description didnt sound so yummy, either.
