You are *still* hung up on *blocking* the viruswith a cloth or non-N-95 mask.That is *not* the purpose of wearing a mask ... homemade orof the non-surgical type."coughing into a petri dish"? Of course the virus willland there.Have the person holding the petri dish stand 6-10 feetaway from the person coughing. Test wearing a maskand without a mask. Let us know the results.The point is they don't know and with no standards on what a "mask"is, they will never know. If a real surgical mask won't work (in thestudy) how in the hell is one of those fishermen's sun block thingsdoing anything?

N95 seems to be a standard. Furnace filters and vaccum cleaner
bags claim to adhere to various standards. That study done with
5 subjects seems pretty hokey and un scientific.

There is very little about this mask idea that is scientific. N-95
might be the standard but only if you can find them. You also need to
get the ones without the valve in front or don't bother. The valve
opens when you exhale so it isn't doing anything.
I haven't seen many 95s, most are just some kind of do rag.


With so much unknown about this virus there are only assumptions
we have to deal with currently.
1 It spreads fast.
2 It kills quickly.
3 Treatment seems to be attacking the symptoms and hoping for the best.
4 Most will survive.
5 Aquired immunity is uncertain.

If there is no immunity, we are all going to die. That is unlikely
tho.

6 The particle size has been estimated at 1 to 3 microns.

You are off by a factor of 10. The virus is 0.1 - 0.3 microns.
An N-95 is not even certified to stop it.
(95% of things 0.3 microns)

7 Whether the virus needs a live host has been debated.

It can live without a host, it just can't replicate seems to be the
consensus.

8 Far to many people are ignoring all precautions.

Define "all precautions". Most people are distancing around here, it
is just the mask thing that is being debated.

9 Dr. Fretwells assesments may be correct but I'm not betting my
life on it.
We wear masks and gloves as appropriate

Improperly handling masks and gloves makes them more of a vector for
the disease than protection from it. It is no accident that in a
medical environment these things are "use once and throw away" in the
biohazard container.

We wash hands a lot
We try not to touch our faces
We social distance and monitor people nearby for behavior
Anything we purchase gets disinfected with Lysol in the car and or
in the garage before bringing into the
house.
In general, we follow the latest advice from the heavy hitters.


Do whatever makes you feel good.
