Great news for NY metro: Over 2.8 million in NY metro have Covid antibodies as of May 6, 2020, per CDC tests, quadruple the number in CDC NY metro test five weeks earlier:
Second NYC CDC test: April 25-May 6: 2,832,000 test “positive,” 23% of the population had coronavirus antibodies present in blood samples, [10 times higher than reported cases showed”] which is consistent with the timing of the outbreak throughout New York. The results also fell in line with a [NY] state-run survey that was conducted around the same time. Testing positive for antibodies means they’ve “been infected” at some time in the past, often without knowing it, having few or no symptoms, and may never have symptoms...."The results reported by the CDC are adjusted for false positive and false negative results."
…………………………….
First NYC CDC test: March 23-April 1…642,000 tested “positive” for Covid antibodies, about 7% of population, meaning persons had been “infected” sometime in the past, most not having experienced symptoms, and may never do so.
…………………
Having 23% with antibodies as of May 6, NYC metro is well on its way to herd immunity. Since we’re now in late July, the percentage with antibodies is likely even higher. Wide acquisition of antibodies by healthy population is the only method guaranteed to stop a virus. The NY metro antibody success is amazing considering brute force government barriers put in the way of their creation, wittingly or not. We desperately need more “cases” and “positive tests” in order to achieve immunity. Instead, we’re erroneously led to believe the opposite, that each new “positive test” or “case” even among young, healthy people, is a horrible thing, death may be imminent. 2.8 million New Yorkers know that’s not so...."The results reported by the CDC are adjusted for false positive and false negative results."
Governments have no power over viruses. They’re not in the game. The only guaranteed killer of viruses is enough healthy individual human beings being exposed to the virus, fighting it off, and developing antibodies. Antibodies are created when the body fights an infection, such as Covid-19. This “fight” is how individuals develop immunity. Once the virus has said hello to the world, if enough average, healthy individuals, one by one, let the virus into their body and successfully fight it off, herd immunity is acquired and the virus ends. “Infected” persons often experience no symptoms:

July 21, 2020, “CDC data shows coronavirus infections far higher in NYC than reported cases indicated,“ Staten Island Advance, Joseph Ostapiuk, Staten Island, NY
“Data published Tuesday [7/21] by the Centers for Disease Control and Prevention (CDC) showed that actual coronavirus (COVID-19) infections in New York City were at least 10 times higher than reported cases showed.
The preliminary findings published by the CDC analyzed seroprevalence — the presence of a virus in a population based on blood samples — in 10 different cities and states, and found that actual numbers of people [with antibodies and with no symptoms] infected with the virus in this [NY metro] region was actually between two and 13 times higher than was previously confirmed through positive test results.
The CDC data suggests that wide swaths of the population in these areas were asymptomatic or did not seek medical care....“Many of these people likely had no symptoms or mild illness and may have had no idea that they were infected.””…

Added: NY metro acquired antibodies early: In April nearly 25% of New York City residents tested positive for coronavirus antibodies:
April 27, 2020, “Latest coronavirus antibody testing shows nearly 25% positive in New York City,“ Staten Island Advance, Paul Liotta, Staten Island, NY
“Nearly 25% of New York City residents tested so far are positive for coronavirus antibodies, according to the latest data available from the state….
Cuomo has repeatedly pointed to antibody positives as a sign that people could begin to safely return to normal life. Most antibodies from coronavirus strains, including the four that cause the common cold, provide [at minimum] temporary immunity to those infected.“…

“What Is an Antibody Test?
An antibody test is a screening for things called antibodies in your blood. Your body makes these when it fights an infection, like COVID-19. The same thing happens when you get a vaccine, like a flu shot. That’s how you build immunity to a virus.
You may also hear it called a serology test.
The antibody test isn’t checking for the virus itself. Instead, it looks to see whether your immune system — your body’s defense against illness — has responded to the infection.
How Does an Antibody Test Work?
A technician will take a bit of your blood, like through a finger prick. The test looks for one or both kinds of antibodies to SARS-CoV-2, the virus that causes COVID-19:
*IgM antibodies, which happen early in an infection
Most people have IgG antibodies about 14 days after symptoms start. They usually stay in your blood long after the infection goes away, but we don’t know how long that is for the new coronavirus.
What’s the Difference Between a Coronavirus Test and an Antibody Test?
A coronavirus test, sometimes called a diagnostic test, looks for signs of active virus. It’s simpler and faster than an antibody test. But it tells you only if you have the virus in your body at the moment when you’re tested.
An antibody test shows that you had the virus at some point in the past. It could be gone, or you could still be contagious.
Why Do We Need Antibody Testing?
You could have SARS-CoV-2 and not know it. Not everyone who gets it has symptoms. Experts hope antibody tests can give health officials a better idea of how common the virus is.
Once scientists know who has had the virus, they can find out how sick [if at all] it makes most people. And they can study what happens if people who’ve had it come into contact with it again. Along with other scientific information, this can help researchers understand who might be immune to the virus.
The hope [proven beyond a doubt by 2.8 million New Yorkers] is that people with antibodies to COVID-19 can safely get back to work, and normal life, quicker….
Researchers are studying how antibodies in plasma donated by people who’ve recovered from COVID-19 might help those who are ill with the virus. Early research shows that this plasma may help sick people get better faster….
Are Antibody Tests Accurate?
Companies make their own claims about the accuracy of their antibody tests. Some say it’s up to 100%. Government researchers are studying how well the tests are working, but it’s too early to say for sure….["The results reported by the CDC are adjusted for false positive and false negative results."]
It’s important to note that some tests can mistake IgM antibodies from other coronaviruses, such as common cold strains, for SARS-CoV-2 antibodies….
What Do the Results Mean for You?
If you test positive for SARS-CoV-2 antibodies, it probably means you’ve had the virus. It’s also possible to get a “false positive” if you have antibodies but had a different kind of coronavirus.
A positive result might mean you have some immunity to the coronavirus. It’s too early to know how strong it is or how long it might last.
A negative result means you haven’t come into contact with the virus or you haven’t had it long enough to make antibodies. You could also have been exposed and not have antibodies. This is called a false negative.
No matter the result, if you don’t have symptoms, you don’t need follow-up. But if you do, you might have a diagnostic test to look for signs of active virus.”…
