CDC Releases Results from Seroprevalence Survey
Wilton's Hamlethub ^ | 26 June 2020 | Written by State of CT

Posted on 07/05/2020 5:32:28 PM PDT by Grandpa Drudge

Today, Governor Ned Lamont reported CDC results from the first six sites of large-scale seroprevalence surveys, including Connecticut.

The U.S. Centers for Disease Control and Prevention today released the results of the first six sites involved in its large-scale seroprevalence survey, which includes Connecticut. The federal agency partnered with commercial laboratories for the survey that tested de-identified clinical blood specimens for SARS-CoV-2 antibodies. The survey included people who had blood specimens tested for reasons unrelated to COVID-19, such as for a routine or sick visit blood test by commercial laboratories in participating areas.

In Connecticut, the survey estimates that 4.94 percent of the state’s population was positive for antibodies, after age and sex-standardizing to census data and after accounting for the sensitivity and specificity of the CDC assay used. The samples were collected between April 26 and May 3. Connecticut had the second-highest seroprevalence in the first round of the study. Blood samples from approximately 1,400 people in the state were tested.

More data on the survey can be found on the CDC’s website:

There are several important points to be made:

1: In Connecticut, the survey estimates that 4.94 percent of the state’s population was positive for antibodies, after age and sex-standardizing to census data and after accounting for the sensitivity and specificity of the CDC assay used. The samples were collected between April 26 and May 3. Connecticut had the second-highest seroprevalence in the first round of the study. Blood samples from approximately 1,400 people in the state were tested.

2: That data was from early in this pandemic, well before the peak infection rate, and obviously much lower than the percentage that would test positive today.

3: Following the link to the CDC website seems to reveal that this was the most recent seroprevalence survey results produced to date.
https://www.cdc.gov/coronavirus/2019-ncov/cases-updates/commercial-lab-surveys.html

4: In spite of the well documented importance of seroprevalence surveys to properly track, forecast, and manage response to this pandemic, apparently NOTHING is being done about seroprevalence surveys for Covid-19 today.

Here is the actual survey results, from the CDC Commercial Laboratory Seroprevalence Survey Data referenced in this thread:

This is also PROOF that health facilities keep your blood samples and use it for other reasons than what they tell you.

And "de-identified", my foot. Don't believe a word of it. They're building a DNA database.

I think it's much worse than that!

It is also very strong evidence that the CDC is NOT dedicated to help manage this pandemic, instead it is the main participant in the fear mongering and political strategies that are currently destroying our economy.

They may have more recent data (they almost certainly do), but are not publishing it yet.

They might say that it needs to be verified and analyzed first - but they may be dragging their heels because of the implications of what they are seeing.

As you point out, it is likely that many more people have been exposed since the beginning of May - and death rates are dropping.

These results are headed in the same direction as Stockholm’s.

The numbers are much much lower than expected. Herd immunity is just not going to happen with this number profile, even if the measurements were early. NY was already killing 8-900 people per day in this time frame.

The most recent study on antibody longevity says, essentially, 2 months. And that is why Stockholm is so low and why we’ll see the same here. The antibodies disappear. They are not immortal. They die and the body disposes. The Memory B cells apparently don’t produce more after 2 months.

Does “seroprevalence” mean human antibodies or corona DNA?

Whichever one, you still have to worry that 1,400 preserved blood samples are not statistically representative of the general population.

In any event, I am glad they are making an effort to track the historical growth of this disease.

Sorry - I read right past the antibody statement.

Question withdrawn.

Thanks for posting.

I agree. I think the CDC is one of the most incompetent and malevolent government agencies, and that’s saying something.

Yeah, a two-month old survey is ridiculous.
Haven’t seen any useful reporting of antibody testing results lately.

Re: “The numbers are much, much lower than expected.”

Less than a week ago, the CDC publicly stated that 5% to 8% of the USA population is - or has been - infected with COVID-19.

The confirmed infection rate for USA 35.5 million PCR tests - spread across four months - is 8.1%.

To my eye, the USA and Europe all look like they are in the 10% to 15% total population infection rate.

Hopefully, SARS 2 will mutate itself out of existence just like SARS 1 did.

Highly effective vaccines for common cold viruses like coronavirus are still decades in the future, if ever.

Re: “The most recent study on antibody longevity says, essentially, 2 months.”

George Floyd (”I can't breath”) got swabbed in the ER the day he died.

The PCR test found coronavirus DNA in his sample - that was eight weeks after he first tested positive for COVID.

So, his antibodies disappeared, but he still had corona DNA in his mucous?

That's hard to believe.

They publish mountains of data, an a daily and weekly basis.

The CDC documents COVID-19 Serology Surveillance strategy, types, and data at:
https://www.cdc.gov/coronavirus/2019-ncov/covid-data/serology.html

The current summary from CDC as of June25, 2020 is at this link:
https://www.cdc.gov/coronavirus/2019-ncov/cases-updates/commercial-lab-surveys.html

Note that all six surveys reported ended long before the peak infection period of this pandemic (last were Utah and Connecticut ended May 3).

The only current Serology Surveillance surveys not reported here are San Francisco and South Florida, neither of which would be of much relevance to the USA as a whole.

So I submit that they do NOT have any current data, and in fact are not even looking. That seems completely unacceptable to me!

It doesn’t matter. Either you’ve had it or maybe you will get it

All the antibody testing does is lower the R0 and the over all mortality rate. We already know tjis is more like a bad flu than the Black Plague

Go. Live your life

Not looking, because they know that what they will find, will not support the political narrative they prefer?

“Seroprevalence” identifies human antibodies, in this case antibodies to SARS-CoV-2 (Covid-19).

And your term "corona DNA?" is incorrect. SARS-CoV-2 is an RNA virus.

Your final comment "In any event, I am glad they are making an effort to track the historical growth of this disease." seems naive to me.

The point of this thread is simply that they are NOT doing important up to date seroprevalence surveys, necessary to properly manage this "pandemic".

I hope the Wuhanvirus/covid sars2 disappears also; I don’t want the deepstate/Dems/RINOs making a vaccine mandatory .

You say "All the antibody testing does is lower the R0 and the over all mortality rate."

Gibberish! The fundamental purpose of antibody testing is to learn what percentage of a population has been previously infected, in order to improve understanding and planning measures to combat a "pandemic" such as Covid-19.

This is probably the most critical data required to evaluate the responses required to optimize our defenses to this virus, yet all we have so far is pseudo-scientific speculation and guesses about this critical percentage.

The result so far is what we have all suffered in this drastic shutdown.

Completely agree. This is old info.last info shows a much higher rate of seropositvity versus reported case. My uneducated guess is the number of seropos. is about 15 times the number of confirmed reported cases. Plus many infection are just not even bothered with. Infectivity might be as high as 30 times confirmed cases. We won’t find out till we’re all dead or the virus mutates itself out of pathogenicity.
