UNC announced yesterday that the positivity last week was over 31%. 

That is not dead which can eternal lie, and with strange aeons bring us some web forums whereupon we can gather

Iowa State is at ~14% after the first week of classes.Ralph-Wiggum wrote: Tue Aug 25, 2020 2:06 pm UNC announced yesterday that the positivity last week was over 31%.
During the first week of classes (Aug. 17-23), 957 students, faculty and staff were tested on campus with a total of 130 positive cases for a positivity rate of 13.6%. There are currently 204 positive individuals still within their 10-day CDC-defined isolation period. Nineteen are isolating in on-campus housing. There are 385 individuals still in their 14-day CDC-defined quarantine period due to close contact with a known positive. Thirty-one of these individuals are quarantining in on-campus housing.
“We are monitoring the data closely to quickly identify and address trends,” said Kristen Obbink, ISU’s COVID-19 public health coordinator. “The university is taking a targeted approach with testing, which allows us to take the appropriate steps to reduce the spread of infection. Our public health team is providing case investigation and contact tracing. We also have adequate isolation and quarantine housing available.”
I've seen them with higher numbers depending on how you break them down and they don't even count antigen tests.Smoove_B wrote: Tue Aug 25, 2020 2:15 pmIowa State is at ~14% after the first week of classes.Ralph-Wiggum wrote: Tue Aug 25, 2020 2:06 pm UNC announced yesterday that the positivity last week was over 31%.

Whatever agency that would handle such a novel thing should probably have a catchy name that can be referred to by three initials. And maybe the first and last initial could be the same?Smoove_B wrote: Tue Aug 25, 2020 2:28 pm Hadn't seen that, ugh. If only we had some type of gigantic, all-encompassing policy that every state was following. I'm not sure what type of agency or public official would help to see that happen. Maybe in 2021 we'll create a system that's never before be in place to address this.

I thought the key was *external* air flow, not just air flow/recirculation. Our company building management and school have both mentioned specifically that they've greatly increased external air intake.El Guapo wrote: Wed Aug 26, 2020 10:50 am Just looking at this, and it reminded me of a question that I've been thinking about. How do I judge whether a place is well ventilated or poorly ventilated? I assume it's mostly about whether there is regular air flow? Early on I had been thinking that air flow (from air conditioners or whatnot) was bad because it would spread virus particles around. But maybe it's good because it disperses virus particles rather than letting them accumulate in particular areas?
I just wish someone in the Federal Government would have thought to create a Pandemic Playbook and handed it off for future leaders to follow.

Right - dilution is the solution. You're ideally mixing in fresh/outdoor air and actively removing the "stale" air from the indoor environment. The rub is how then you're moving the air around and getting it away from people. If you're blowing or drafting it and creating air currents, is that increasing spread by moving particulates?Zaxxon wrote: Wed Aug 26, 2020 10:56 amI thought the key was *external* air flow, not just air flow/recirculation.

Is it fully indoors, i.e surrounded by 4 walls? Poorly ventilated. Is there an open window? Slightly better. Are there 2+ windows that can promote a draft? Better. Are you under a pavilion / tent structure that has no walls, only a ceiling? Even better.How do I judge whether a place is well ventilated or poorly ventilated?
My rule, if it has open doors/windows then it's ventilated. The more, the better. Internal recycling, even if it has external intake, doesn't move the needle. You have no idea how they work or how they air circulates.El Guapo wrote: Wed Aug 26, 2020 10:50 am

Or just assume poorly ventilated if reasonable to do so.Smoove_B wrote: Wed Aug 26, 2020 11:32 amRight - dilution is the solution.

Think about using Testor's model cement or a can of spray paint. If you can imagine that you'll be choking or your eyes will be burning if you try to use it in the area you're currently in, it's poorly ventilated.
I take it that this is an open question for which we don't really have a great answer?Smoove_B wrote: Wed Aug 26, 2020 11:32 am The rub is how then you're moving the air around and getting it away from people.

Volume is more of a factor in a place like that. There is enough air volume that direct ventilation isn't as important.ImLawBoy wrote: Wed Aug 26, 2020 11:40 am What about a recently constructed (last 5-7 years) supermarket? High ceilings, cranking air conditioner, but no open windows? Some food prep areas with what I assume are externally venting fans.
The best antibodies.LawBeefaroni wrote: Wed Aug 26, 2020 11:50 amThis morning she told me that she tested positive for antibodies. "A lot of them!"
Unless the airline industry is lying to me, cabin air is run through HEPA filtration - which (in theory) should be removing larger (but still microscopic) virus laden particulates and (in theory) naked virus just floating around. I say "in theory" because we just don't know for sure - we're guessing based on what we do know and what the HEPA filters are capable of. I think the mountain of data is strong, but until it's been confirmed in a lab we won't have a demonstrated verification of the theory.El Guapo wrote: Wed Aug 26, 2020 11:44 am Part of it is also that I've seen a few articles that suggest that airplane ventilation systems are great and that as such the risk of coronavirus spreading on an airplane is much lower than one would think. Not that I'm planning on flying anytime soon, but it raised the question for me of the ability of a good ventilation system to make an indoor environment relatively low risk.
A relative of mine was planning on some air travel recently, and I did some Google research trying to find examples of why air travel is a horrible idea. I ended up finding similar things to what you're reading -- being on an airplane with other people is relatively the same level of risk of sitting in the same arrangement with them on benches in a large building. The airplane risk seems to be more about direct close interaction with people seated near you, not about growing accumulations in the air like in the church choir or restaurant incidents.El Guapo wrote: Wed Aug 26, 2020 11:44 amPart of it is also that I've seen a few articles that suggest that airplane ventilation systems are great and that as such the risk of coronavirus spreading on an airplane is much lower than one would think.
Out of the loop... bammed?Ralph-Wiggum wrote: Wed Aug 26, 2020 2:56 pm Not surprisingly, reports are coming out that the change in the CDC guidance about who should be tested (i.e. stating that asymptomatic people in contact with infected people don't need to be tested) were directed by the WH. It seems like a blatantly obvious way to artificially reduce infection numbers, especially now that schools and universities are opening up and causes huge spikes in infections. And, like everything directed by the WH re; Covid, it has the intent of making things look better while making the actual situation much worse.

We should be doing this for *all* schools that are having in-person instruction right now, K-12.My university is testing all students and staff 2x/wk.
So it processed 17,000 coronavirus tests yesterday.
That is 2.7 percent of all testing done across the entire United States.
That is not a typo.
Well they are asymptomatic so they don't need to be tested, right?Smoove_B wrote: Wed Aug 26, 2020 7:11 pm In case anyone is looking for perspective on testing:
