Bad News Thread

This is a very interesting breakdown. The red states were the leaders in vaccination early on. Now the blue states are. No explanation is given but given the red states were basically handing them out with fewer requirements, my guess is that that we've reached vaccine glut in the more vaccine reluctant red states.

 
And so you couldn't help yourself.

Did you know that oxygen molecules are small enough to pass through the mesh of a mask?

I passed it on, without comment. My son BTW had a similar experience in a GK session when he was wearing a mask at the request of his partner for some close work together. If oxygen molecules can pass so readily through I'd think the same for aerosolize virus particles.
 
You could make a weak argument for Clairemont maybe, but nothing remotely close to the Texas areas. El Cajon is very integrated in terms of Chaldean and white, Latino, but not in terms of blacks (all sorts of immigrants though in city central). The black community in El Cajon is limited to some isolated, small pockets. Those other communities are integrated with Latinos, but not by any stretch of the imagination with Blacks. Not saying there is anything wrong with any of these communities. My point is that I appreciated the racial diversity I saw in Texas which is not something I've seen in Socal, but I haven't been to Moorpark. Again my observations were anecdotal.
The places I have been in Texas are all pretty segregated, but I don’t live there.

Oxygen molecules have a diameter of about 300 picometers. Coronavirus diameter is about 100,000 picometers, not surprising since each individual coronavirus is composed of thousands of atoms. Aerosolized droplets are larger still, whether or not they contain any virus particles.

It’s why I’ve said we should be doing surgical not cloth. The cloth masks are not designed to distinguish between aerosolized particles and air. Bigger gaps. The surgical and n95 masks are designed specifically with this in mind (though the surgical aren’t very tight fitting...if you can smell someone smoking near you then there’s an issue)
 
Cruz grandstanding. Discrimination against Asians (or any race) on the basis of race in college admissions is already illegal.

Maybe grandstanding... I saw it as more of an affirmative action issue. Protecting Asians from Race based admissions policies would make affirmative action initiatives hard to implement without impacting the Asian community. That also would explain the straight party line vote.

The question is better put to Senators Duckworth and Hirono.
 
Been saying :)
You might want to read the actual paper. It doesn't say what you've "been saying".

The key assumption in the paper is the assumption that the air in the room is well mixed. In other words, they begin by assuming that viral concentration is equal in all parts of the room. This makes the 6 foot versus 60 foot risk conclusion pretty much inevitable.

The section "beyond the well mixed room" is much more interesting. It gives a detailed explanation of what air flow paths exist, and how masks, distance, and being outside each work.

The simple risk is called respiratory jet. This is the direct wind created by your breath and speech. It is also a region of higher virus concentration. The higher viral load extends about 2m if unmasked. If you wear a mask, the air is slowed and respiratory jet doesn't go as far. Instead, it mostly goes up as hot air rises. (Masks and distance out to 2m help with this part of risk.)

The less direct risk is just increasing concentration by being in an enclosed space. If I am sick and spend 3 hours in a room, then I have added 3 hours of exhaled virus to the air. The longer I spend, the higher the viral concentration. And, the longer you spend in that room, the higher your exposure.

Cloth masks and distance beyond 2m do not help with this part of risk. N95 masks or better ventilation do help. Or, just avoid indoor spaces and go outside.

In all, the authors give a really good description of why masks, distance, and being outside are helpful, and the limitations of each.
 
Recently she’s been saying a lot about duration of exposure.
It’s been the factor they’ve been missing and the key explanation I think that explain dads “masks work” v real world results.

I’ve also been saying that the 6 ft thing was pseudoscience particularly when indoors

dads mind just blows a gasket that I always seem to get there before his experts. Just teasing with this last part :)

If someone is smoking near you you probably aren’t indoors. If you are yes there is an issue. It continues to puzzle me why the simple measures to limit potential exposure are so hard for people to grasp . . . like those driving alone masked? Lol!
