    I can agree with that, but I never read Putin's propaganda knowingly.

    It lends itself to a particular kind of informed use. It's a decent starting point for finding citations to other relevant sources (and in fact it doesn't intend to be anything else; if you start adding original research there, it gets OR-tagged and removed).

    Every page there has a 'history' tab, which is worth checking to see if the page you're reading is in the middle of some edit war between people of opposed viewpoints. If it is, you can start comparing past versions of the page, going a few alternating edits back. From that you learn which points the contending factions both more or less accept, and which ones they keep changing on each other. Lot of information there between the lines.

    That wiki link doesn't paint a great picture for MB/FC.

    From the above wiki link : "The Columbia Journalism Review describes Media Bias/Fact Check as an amateur attempt at categorizing media bias and Van Zandt as an "armchair media analyst."[3] The Poynter Institute notes, "Media Bias/Fact Check is a widely cited source for news stories and even studies about misinformation, despite the fact that its method is in no way scientific."[4]"

    The Poynter reception towards MB/FC could be biased towards preventing perceived competition in the niche.

    Even if Poynter is correct, I would be skeptical given the previous experience.

    Excellent sources:
    The first article reminded me that smallpox was initially treated by using cowpox. A family of related virus could induce a less lethal infection and a broad immunity response. That the earlier SARS patients showed a latent response to SARS-CoV-2 makes sense not that a SARS vaccines make sense without more through testing.

    The second article surveyed the symptoms and outcome. The biological markers were discussed and confirmed my career choice of not biology and organic chemistry.

    Thanks,
    Bob Wilson

    Wikipedia works on the old concept of the wisdom of the commons, which is basically the idea that a group can arrive at the right answer as well as a single expert on the matter.

    Wisdom of the crowd - Wikipedia

    Yep, I sited Wikipedia, but there is 35 cited sources to that article if you want to dive deeper on the topic. And the view history button is right next to the site's search bar.

    The Wikipedia community does take their task of keeping articles accurate seriously. While it is possible for just about anyone to make changes to an article, incorrect info tends to get fixed pretty quickly. they'll go as far as blocking IP addresses. Happened to the Colbert Report office when they did it.

    Where does that Media Matters quote come from? It isn't on the Wiki page, nor the more recent previous ones.

    My point is not the doubt on how well Wikipedia editing works to capture the facts and truth and dissimilate the information to the general public. I know very well how Wiki works. My point is that I simply put less trust in any information that has not been proven by rigorous scientific inquiries. Wiki or anything I find in media, be that on the internet, on printed papers, or from recorded voice or movie, all tend to lack such proof. Unfortunately, many recent publications on medical and scientific journals on the subject of COVID-19 also lack such proof. For the urgency of the situation, scientists, medical doctors, journal editors, and general audience all are accepting the quantity over quality.

    My point was simply that if you are using the Wikipedia project as something other than a place to follow links from to find the sources that meet your criteria, you are disparaging a screwdriver for not being a hammer.

    Again, I have no problem using Wiki for general information just as you have described how it should be used. I am not complaining about the credibility of the Wiki information. I am simply stating that it is not what I trust most. In my line of work, it is very important to realize that Data is not information, Information is not knowledge, Knowledge is not understanding, Understanding is not wisdom. And I know the facts and truth can be found somewhere and anywhere in between those transitions, but along with a lot of misinformation and lies.

    It's also a little weird when I say Wikipedia and you say "Wiki" like they're the same thing.

    these articles are like ev articles on million mile batteries and 5 minute charging.

    i'm still waiting for the shallow nasal swab and 5 minute results :rolleyes:

    At sunrise and sunset, I measure temperature and O{2} level ... close enough.

    The Covid-19 test i had a couple weeks ago (part of a community surveillance sampling program, not based on symptoms or contacts) used a self-administered nasal sampling swab meant to go just 1 inch into the nose. That is certainly shallow compared to the original nasty swabbing method. When the spouse earlier needed a test as preparation for a medical procedure, she also was given the same shallow self-administered version.

    I can't help you on the 5 minutes results though.

    Our estimated asymptomatic proportion is at 17.9% (95%CrI: 15.5–20.2%), which overlaps with a recently derived estimate of 33.3% (95% confidence inter-val: 8.3–58.3%) from data of Japanese citizens evac-uated from Wuhan [13].
    . . .
    Our study is not free from limitations. First, laboratory tests by PCR were conducted focusing on symptomatic cases especially at the early phase of the quarantine. If asymptomatic cases were missed as a result of this, it would mean we have underestimated the asympto-matic proportion. Second, it is worth noting that the passengers and crew whose data were employed in our analysis do not constitute a random sample from the general population. Considering that most of the passengers were 60 years and older, the nature of the age distribution may lead to underestimation if older individuals tend to experience more symptoms. An age standardised asymptomatic proportion would be more appropriate in that case. Third, the presence of symptoms in cases with COVID-19 may correlate with other factors unrelated to age including prior health conditions such as cardiovascular disease, diabetes, and/or immunosuppression. Therefore, more detailed data documenting the baseline health of the individu-als including the presence of underlying diseases or comorbidities would be useful to remove the bias in estimates of the asymptomatic proportion
    . . .

    Like most things in life, there is a distribution of metrics. Fortunately, I have a second subject, my home-bound wife, and she shares similar temperatures and O{2} levels. If we take their 13% probability of being asymptomatic, as a family we have a 17% * 17% probability, 2.9%.

    So as long as we remain fever-free, <98 F, and normal 98% O{2}, there is no reason to put a further load on medical services. If symptoms show up, we'll call and use the ER admissions screening. Waiting 7-10 days for test results doesn't make a lot of sense as today the only response is to quarantine. We're already home bound.

    Source: Two U.S. bases in Okinawa on lockdown with 62 coronavirus cases confirmed | The Japan Times

    U.S. forces told the Okinawa government the cases were confirmed between Tuesday and Saturday at U.S. Marine Corps Air Station Futenma and Camp Hansen, and the two bases had been locked down, prefectural government officials said.

    I never visited Futenma but passed through Camp Hansen. When you arrive, Camp Hansen had the holding company until you are sent to your base. You spend about a week there while they sort out any ill or contraband. That is also where I learned about 'prickly heat' where your skin feels like small biting insects are crawling all over. A quick, cold shower solved the immediate problem long enough to get some sleep.

    @2417 "as a family we have ..." I have no idea what this is about. The 17% has nothing' to do with these two people here, and these are anything but independent probabilities that ought to be multiplied.

    You know better. Keep external emitters away. Focus home on positive things. Do not 'numbers' the wife.

    Do your finger-eating dogs survive? Focus on them. Happy happy happy.

    % COVID-19 positivity rate among the asymptomatic population in our region is extremely low. It is more like 0.1% or less among those who have been tested without any symptom or contact with known positive individual. It is nowhere close to 17% reported for the closed population of 3,711 passengers and crew on the Diamond Princess in enclosed crowded space of the ship with 634 confirmed positive cases. That estimation model would not apply to most open population.
