WHO's 10 percent number may well be an underestimate.
In Ontario, about 1 percent were found to have antibodies to Covid in the blood. However, that was in June. We are now in October and that number is probably at least doubled. So 2 percent.
Studies have shown that seroprevalence (antibodies to Covid in the blood) alone underestimates antibody response, perhaps 5 fold. Read this carefully, from https://www.bmj.com/content/370/bmj.m3364
Serum IgA antibody responses may be detectable earlier than IgG and IgM responses1617 and can persist for at least 38 days in hospital patients recovering from covid-19.18 This is consistent with a recent Cochrane review, which found that IgA based serological testing had greater sensitivity than other methods.5 A recent seroprevalence survey of 1473 residents (79% of the local population) in Ischgl, Austria, using a combined IgG and IgA approach found SARS-CoV-2 antibodies in 42.4% of those tested, far higher than rates in previous population based surveys of other infection hotspots.19 Similarly, IgA antibodies were detected in 11% of 1862 people sampled from the general population in Luxembourg, whereas IgG antibodies were found in only 1.9%.20
Finally, mucosal and bloodborne immune responses may provide complementary information crucial for accurate assessment of viral exposure in both individuals and populations. In a cross sectional study of UK healthcare workers, combined IgG, IgA, and IgM testing for SARS-Cov-2 spike protein in saliva samples identified 15% of participants as positive despite a negative serum test result.4
So increase the 2 percent fivefold to 10 percent.
The above is for people who generated an antibody response. What proportion of people are infected, and their T cell cross immunity (among other things) protects them, without a need to even get to the antibody production stage?
So increase the 10 percent at least twofold, and we have the number of infected at over 20 percent.
Now, perhaps at least half of the people very lightly exposed to the virus even progress to what may be termed infection. So perhaps at least 40 percent of the population in Toronto may have already been exposed to the virus and are immunologically primed to defend against another exposure.
Thanks Mark. I echoed into this thread because you chimed in. I was going to go through a similar logic, but the thread hijacking had me frustrated, so thanks for spiking the volleyball! Also note that Ontario was testing IgG antibodies only.
This whole area is of course relevant. Because the World Economic forum considered serology a basis for international "passports" that are being rolled out. https://nationalpost.com/trave…lling-during-the-pandemic
In their proposal, Onfido said immunity passports are “the linchpin of a new normality.”
Germany, Indonesia, Italy, Israel, Colombia, Argentina, Estonia and the U.S. are also considering implementing immunity passports like CommonPass.
As I recall, the usual suspects on this forum were even recently having a field day claiming there was no master plan wrt Covid and no control system would be introduced. The virus is equivalent to a bearded guy in a cave - having brown skin to me this is a particularly egregious and old meme used on populations that works as ridiculous as it sounds. But it plays on our inbuilt fear of the other. They do this decade after decade. What is obvious now, is they are turning the messaging around and turning it on the scary viruses as the new bogeyman and simultaneously pushing the masses to apologize for their racist crimes. I see more and more webexes beginning with "apologies to our native people." I'm all for apologies and reconciliation. But how about we acknowledge these are manufactured now in this moment to make us feel like there are traders against in the midst. To steer the conversation to defunding police forces, rooting out "racists" from our midst, and having us all participate in this collective consciousness. They want to create a culture - meanwhile our governments are not working on ending the prison complex - the institutionalized system of racism (because sadly, some people are worth more economically in jail than out of jail). Rather than actual positive change, a whole new set of agendas centered around societal control is rolling in. You know how they used to message in the airports "Terrorism - if you see something say something." They are spinning society but now it is about racists, elite-crime conspiracy theorists, and anti-vaxxers.
As we now know these long terms plans like immunity passports (and more transhumanism agendas) are already sitting on the shelf - created over many years. That is the only reason nation states are able to move into implementation so quickly. Most govt telephone lines cannot even answer a medium difficulty tax question with reliability, nor can govts balance a budget - all the worlds budget calculations can be done rapidly on the computing power of a cell phone this is not complex stuff, public healthcare moves extremely slowly even in crisis (nobody talking about Vitamin D for months into a pandemic), one could go on...one would think committees would be setup looking into HCQ or other treatements. Or maybe strategies to effectively protect older people - especially in nursing homes.
If you are seeing private-public partnerships around major endeavors like "immunity passports" that means behind the scenes a puppet master has already decided that's what we are doing. So a whole new range of equipment and procedural appendages will be installed - kind of like terrorism security scanning at airports, no-flylists....but now it is for your body. It is profligate use of resources. It would take an immense amount of stupidity to believe this is about public health or saving lives. The costs of war project by Brown University is worth checking out. A short summary: 37 million were displaced by post 9/11 wars, $6.4 Trillion was spent on these wars. Why do they hate us in the middle east? What infectious ideology do they have and how do we bomb the crap out of it? In truth, a particularly infectious form of insanity coupled with big technology setup by elite criminality is looting the world. The populations are the cattle they are herding and culling and making hamburger meat out of us. And it is happening again. Private equity firms are literally sharpening their knives at this moment...
If this was about saving lives, ~$100 billion per year could end global poverty and thereby bring the basic necessities of life to all those dark skinned people we're supposed to love. And hey, it would create a huge amount of economic wealth and saving of lives -- poverty elimination (not vaccination) is the #1 correlate of saving lives. Isn't that what this is about or did we not get the memo?
