    now regarding you conspiracy bullshit piezoe.....

    Tell me... what I got wrong... about this Covid situation.
    And then tell me if you trust the WHO and what they have been telling us.

    by the way... your explanation here is garbage.

    you are conflating issues which don't go together

    your conclusion is illogical and unfounded

    especially if you actually read what the WHO wrote and said

    here4dnc was correct as he was simply paraprasing if not quoting what the WHO wrote...

    and back when Fauci and others were saying the this was dangerous because many people were aymptomatic and can spread the virus....

    there were no antibody tests yet.

    it IS like the "flu"! The difference is this: No vaccine. No recognized efficacious treatment. So many more end up contracting it, and a correspondingly greater number die from it.

    I am not ignoring your post, but I had trouble understanding it. Perhaps you could re-phrase it.

    This is not just a case of Maria Van Kerkhove walking back a statement.
    The Who wrote this in their June 5th circular titled...

    Advice on the use of masks in the context of COVID-19



    "Comprehensive studies on transmission from asymptomatic individuals are difficult to conduct, but the available evidence from contact tracing reported by Member States suggests that asymptomatically-infected individuals are much less likely to transmit the virus than those who develop symptoms.
    Among the available published studies, some have described occurrences of transmission from people who did not have symptoms.(21,25-32) For example, among 63 asymptomatically-infected individuals studied in China, there was evidence that 9 (14%) infected another person.(31) Furthermore, among two studies which carefully investigated secondary transmission from cases to contacts, one found no secondary transmission among 91 contacts of 9 asymptomatic cases,(33) while the other reported that 6.4% of cases were attributable to pre-symptomatic transmission.(32) The available data, to date, on onward infection from cases without symptoms comes from a limited number of studies with small samples that are subject to possible recall bias and for which fomite transmission cannot be ruled out."

    Well, I didn't need to look her up, she's infamous as "Typhoid Mary," It's still not clear to me what your point is. I'm sure it is a good one, just not sure what it is.

    Typhoid is of course a bacterium and is transmitted mainly through unsanitary practice, quite different from the way respiratory viruses are transmitted (usually).

    No one questions whether a person with a live virus infection but no symptoms can transmit the virus. they can, no question about it. However the number of persons among those infected with a live virus, such as a respiratory virus like the Corona viruses, that don't show any evidence of symptoms is almost certainly far smaller than the numbers being inferred from highly inaccurate antibody tests. There are highly accurate tests specific for Covid -2 antibodies, but these are not the tests being used to generate the bulk of antibody test data for Covid-2 in the U.S.

    This is consistent with the number of asymptomatic covid infections being reported being wildly incorrect. Its based on highly inaccurate antibody testing giving many false positives. The false positives are neither carrying antibodies to Covid-2 nor are they immune to Covid-2. They won't have symptoms, because they have not been infected, nor are they infected; thus their probability of transmitting the virus is zero!

    you are going to have to document that....



    I know from talking with Doctors many people in hospitals in San Diego are now getting tested... Some are found positive for Covid and have no symptoms.

    Yesterday... I specifically asked if they were being tested with the swab test and not the antibody test (because I also suspect some antibody tests are not accurate) ... they said of course.

    The "swab test" is for live virus. It also has problems because it is PCR based and therefore tremendously sensitive to a few molecules of contamination. It depends very much on the skill and knowledge of those doing the lab work. When done properly, it is highly reliable. In the best of world's all positive tests, without symptoms, would be repeated and followed for ten days, and all negative tests with symptoms would be repeated. Seldom happens however.

    Based on meticulous studies of SARS Covid, the percent of Covid-2 infections that remain asymptomatic but produce antibodies specific to Covid-2 should be ~7% . Numbers such as 50-80% are just not believable, and when one looks into the origin of these numbers one invariably finds finger prick antibody tests.
