On the radio this morning they quoted the local hospital director saying they now have a device allowing vents to be “safely used with two patients at a time”. I’m skeptical about which definition of safe they’re using. Or maybe some meaning was lost in summation.
Outdoors the hang time is negligible due to dilution and air movement. The numbe4s you cite are applicable I doors, but go outside and walk by all means. Just stay out of coughing distance of other people.
I guess it is “safe” vs not having a ventilator at all? No, not anywhere near ideal, but if the alternative is to give a patient a 100% death probability vs somewhat less than ideal situation.
Thanks doc! 
Probably a good idea. (Different ICE.)
Some things I didn’t know. Fbook churn, so grain of salt, etc.

This is the reality:

Only a couple of nitpicks:
This virus is an RNA virus. Simply speaking, RNA is a single strand where DNA is a double-strand. DNA and RNA are nucleic acid chains, not proteins. Again, simply speaking, the RNA from the virus hijacks a cell and turns it into a virus factory.
This particular virus has proteins that stud the surface of the lipid layer, which attach it to a cell and provide an opening for the RNA to get inside the cell. Most of the time, human cells are pretty good at keeping foreign DNA and RNA out. That’s why viruses need a “key” to get in. When you hear about this virus attacking the ACE-II receptors, that’s the door they use to get in. The proteins that form the spikes of the “crown” that give it the “corona” name are the key to that door.
I think this is referring to hydrogen peroxide, H2O2. 3% hydrogen peroxide is quite good for antiviral effect; it easily forms free radicals, which form free radicals on the RNA of the virus, cross linking it and tying it in knots. When it’s knotted, it can’t infect cells.
This is almost dangerously too general. Different UV light has different effects. The near UV light that is prevalent in sunlight and “black lights” is almost useless against microorganisms. Mid-UV light, which is present in lower intensity in sunlight (and doesn’t pass through most windows, BTW) is effective, but can take hours to do the job. Deep UV light, that is absorbed in the upper atmosphere and doesn’t reach the earth’s surface, is very effective. But it’s also hard to find. There are mercury lights, xenon lamps, and LEDs at these wavelengths, but they are not household items.
They also depend on line-of-sight. A mask is porous. It is NOT simple to disinfect a mask with UV light. Stanford released a paper on testing of different disinfection techniques for masks, and dry heat, UV light, and 10 min steam were effective while retaining mask filtration properties. Chemical disinfectants were not, as they were detrimental to mask function.
I’m not going to nitpick details but Chinese people I know sure seemed to think that Dr. Li was mistreated by the Chinese government. Somehow I doubt they were swayed by Western propaganda.
Fucking fuck.

Hunt was our best agent!
A stroll through any cemetary from the time (whether big city, small town, or country churchyard) shows an inordinate number of tombstones from 1918. All ages. Sometimes whole families. It was always unimaginably depressing.
Future generations visiting cemetaries will think the same of 2020.
Less children at least (though not unaffected by any means).
sigh… Time for sleep and waking to fight another day, I suppose.

We gotta be careful in so many new ways!
