Deebz attempting to turn the absence of evidence into a man bites dog story. A half-witted jellyfish could make a better point.
At the time Mofro, iceman, and others had good laugh at deebs obviously fake 80% asymptomatic rate. And yeah the quotes don't lie but deebz clearly does.

06-01-2020, 08:36 AM #19878Researchers at the University of Maryland School of Medicine have developed an experimental COIVD-19 test that uses nanoparticles to detect if coronavirus is present in saliva or a nasal swab sample, revealing the results in about 10 minutes through a change in the color of the test liquid, they report in the journal ACS Nano.
"Based on our preliminary results, we believe this promising new test may detect RNA material from the virus as early as the first day of infection," lead researcher Dipanjan Pan said in a statement, noting that additional studies are need to confirm the results. "Many of the diagnostic tests currently on the market cannot detect the virus until several days after infection. For this reason, they have a significant rate of false negative results." If RNA material specific to the new coronavirus is present in the sample, the gold nanoparticles turn the purple test reagent blue.

The doctors quoted describe changes in presentation of COVID-19 using terms that imply changes in SARS-Cov-2, but the two things are distinct. A change to the virus should be detectable genetically, but there are a lot of factors that would change the average presentation of the disease without any change to the genetics of the virus.
A change to the virus would be more convenient, but less severe infections could also be evidence of lower viral loads at transmission, quicker average detection, more social distancing among the most vulnerable--or many other factors tied to behavioral changes. And/or a change in the population itself. Point being, a change to the virus would "just happen" without human actions, but all other explanations imply that something is working.

Totally OT, has nothing to do with my argument.
No point getting into a big argument on inheritances, but it's a fallacy to think the state will make better use of that money than the heirs.
the myth of job creators is. How many more jobs have bezos and the waltons destroyed than created (in this country)?
When combined with supercharged policy to funnel more wealth to these people it's exacerbated further, since they are now richer and even more important job creators! The system is broker than we are and the coronavirus response is just like the social unrest, the result of a complete failure of leadership and the social contract in our country.
Seems like some people are ok with it because they aren't old, have gates around their neighborhood, etc...
Agree on bailouts.

I think I get what you're saying. Reading the article, it's tough to to tell if they're talking about less severe infections or a change to the virus.
I missed this when it came out, but a month ago there was some evidence of the virus mutating to weaker forms, like it did with SARS. https://asunow.asu.edu/20200505-asu-...onavirus-study

Is it the virus that's changed or people's behaviors so that when exposure does occur the viral dose is much lower? If it's the latter then we'll obviously see a spike when things open up. And don't expect a spike to necessarily occur within a week or two--evidence from California and NY that the virus was circulating in the community for quite a while before cases starting popping up.
A third explanation is that only a fraction of the population is susceptible and the virus has run out of victims. No proof of this theory yet, and this has been going on long enough that I would think if there were genetic differences in susceptibility we would know that. But I keep hoping.

Yeah, I think translation might make it hard to tell what they actually think the cause is. And I'm certainly not trying to discredit anyone. The article just seems to state it in a way that implies more than what you'd expect clinicians to know directly (and of course that/they could be right, too, direct knowledge or not). Regardless, they're reporting good news, what's unclear is what is the actionable takeaway?

Currently there's no way to quantify what the threshold is but a higher dose is clearly worse. The number of infected people matters, proximity matters, timing matters, and aiflow whether indoors or out, whether fresh air is brought in or stagnant air is recirculating.
People avoiding indoor crowds, wearing masks, washing hands, staying home when sick and so on might make the difference when it comes to dosage in Italy after the virus was brought under a semblance of control.
Whereas in take it on the chin Brazil poor workers are compelled to keep working, people are crowded together not wearing masks leading to a greater share of the population exposed to the virus at a higher dose. Dosage along with higher pollution levels and less access to health care could explain why coronavirus deaths are skewing younger in eveloping countries.

Yeah, that's the best educated guess. Exposure to high doses would explain why young healthy health care workers died from the virus. The problem, statistically speaking, is it's difficult to test the theory in humans and there's little correlation with subsequent viral loads because there's so much variation when it comes to things like cellular receptors and overall individual health.
In the hamster study discussed earlier the subset of masked hamsters who became infected, presumably receiving a lower dose than unmasked hamsters, had less severe disease indicators.

If we are able to to reduce the amount of viral load in each transmission (through distancing, masks, etc), in theory we should see less severe cases. I wonder if this has a chain effect and eventually leads to the virus petering out...eventually becoming something more flu-like in severity. (wishful thinking)

Temporarily--reducing COVID without killing off the virus probably only lasts as long as the behavior, as oldgoat pointed out recently.
I think it should be possible to at least come up with some estimates for viral loads at certain transmissions that are likely to have occurred in a known setting (patient coughing in a caretaker's face, for example) and show a correlation with severity of the next infection. Something. Samples are not small at this point. Any link between severity and dose is a very useful piece of information.

No. The problem is "there are individuals who have worked so hard to defund and break these social programs for 40 years with success no matter who is in the OO." Some just happen to be boomers.
I'm a boomer and I've never worked towards or supported that goal and I have a great many boomer friends who haven't either. Shortsighted selfishness is not the bastion of just one generation.Last edited by KQ; 06-01-2020 at 12:47 PM.

This is k00l because these animals are inbred, i.e., genetically identical, so there's no variation at the level of individual animals. Differences in disease severity may very well be due to outside factors.

Just a reminder that The Hutch is doing incredible work to genetically trace variants of the virus. Almost 4,000 samples sequenced to date which is how they determined that most of America was seeded with cases from Europe and not China directly.
https://nextstrain.org/ncov/global
You can actually go in and see the variants in each clade which is to say that variation is fairly modest and that NO ONE has connected variation with disease severity (infectivity or virulence) which makes the Italian story incomplete at best. Even IF a variant arises with properties that make it less severe, its propagation relative to other variants depends more on an increase in infectivity and less on a change to virulence. With that in mind, the current version is already highly infectious.

They are golden, as long as their dependence on tourism doesn't bring the virus back. Seems a little like where Montana is, we have all but eliminated new infections, but tourism is a huge part of the economy which is being reopened. "What a nice safe place for vacation....". It worries me, very many think it's done here for good, and have gone back to old habits.
edit: I guess NZ can quarantine visitors, but that will eliminate a lot of interest in tourism.I form the light, and create darkness: I make peace, and create evil: I the LORD do all these things. -אלוהים אדירים

I'm going to keep banging this drum because this is a hugely important resource in my mind. Even if you just look at the table mid-page, it would be worth it.
Read this: https://cdn.hc1.com/docs/covid-19/ae...user-guide.pdf
And then visit this: https://www.aei.org/covid-2019-action-tracker/
Does it have ALL cases, probably not.
It also bothers me that the LRI calculation (and the subsequent heat map) does not factor in the number of test performed.
Also, we don't know if tested is concentration to specific businesses or residences (like nursing homes)
However, you can see the volume of tests for your county and whether there's a spike. The reg version simply breaks the results down by age and gender.
