The following is a brief roundup of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus.
New coronavirus antibody test highly accurate
A new antibody test is highly accurate at determining whether people have been infected with the novel coronavirus, according to a study published on Friday in The Journal of Clinical Microbiology. Researchers at the University of Washington School of Medicine found the test, manufactured by Abbott Laboratories, had a specificity rate of 99.9% and a sensitivity rate of 100%, suggesting little chance of incorrectly diagnosing a healthy person as having been infected and virtually no chance of a false negative readout. Abbott's test has received emergency use authorization from the FDA and the company has already shipped more than 10 million of the tests to hospitals and labs.

Coronavirus antibodies in breast milk may protect infants
Breast milk from infected mothers may contain antibodies to the novel coronavirus that could be protective for babies, a study suggests. "Nursing mothers who are infected with the novel coronavirus should continue to breastfeed throughout their COVID-19 illness and beyond, because (other researchers) have shown transmission does not occur via milk, and we have determined that antibodies are almost certainly there, and may protect their babies from infection," Rebecca Powell of The Icahn School of Medicine at Mount Sinai in New York, who led the study, told Reuters. Her team's report, posted on Friday on the preprint server medRxiv, has not yet been peer reviewed or published in a medical journal. (https://bit.ly/2WHvJcA)

I predict that comments on this thread will go downhill quickly.
The human race survived virus plagues for millions of years until the professional affirmative-action bureaucrat and professional affirmative-action educrat class came along to save us.
Now we are doomed.
Is the antibody test designed to detect a current state of infection or a past infection ? IgM vs IgG antibodies for example
Lol
I can see a market for this...

ABSTRACT
Coronavirus disease-19 (COVID19), the novel respiratory illness caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is associated with severe morbidity and mortality. The rollout of diagnostic testing in the United States was slow, leading to numerous cases that were not tested for SARS-CoV-2 in February and March 2020, necessitating the use of serological testing to determine past infections. Here, we evaluated the Abbott SARS-CoV-2 IgG test for detection of anti-SARS-CoV-2 IgG antibodies by testing 3 distinct patient populations. We tested 1,020 serum specimens collected prior to SARS-CoV-2 circulation in the United States and found one false positive, indicating a specificity of 99.90%. We tested 125 patients who tested RT-PCR positive for SARS-CoV-2 for which 689 excess serum specimens were available and found sensitivity reached 100% at day 17 after symptom onset and day 13 after PCR positivity. Alternative index value thresholds for positivity resulted in 100% sensitivity and 100% specificity in this cohort. We tested 4,856 individuals from Boise, Idaho collected over one week in April 2020 as part of the Crush the Curve initiative and detected 87 positives for a positivity rate of 1.79%. These data demonstrate excellent analytical performance of the Abbott SARS-CoV-2 IgG test as well as the limited circulation of the virus in the western United States. We expect the availability of high-quality serological testing will be a key tool in the fight against SARS-CoV-2.
So the "CRUSH THE ECONOMY" campaign was really not needed.
“The human race survived virus plagues for millions of years until the professional affirmative-action bureaucrat and professional affirmative-action educrat class came along to save us.”
LOL! 50 million died in 1918 flu.
From overdoses of aspirin.
Does anyone have results of recent antibody testing? I looked earlier today but couldn’t find anything except the initial reports out of LA County and Bay Area with estimate of ?15% exposure.
“would it protect me?”
—
You jest, but not a bad question to ask.
Well they seem to want us to be out of the Sun, be too scared to talk to others, etc. So I don’t know if I will ever believe them at face value ever again.
Let’s be honest here. How does a disease with similar contagion vectors as the flu not expose at least 50 million people in the United States alone?
A whole new line of work for a wet-nurse.
IgG
India was the hardest. hit.
The human race survived that.
It will never survive “saviors.”
Mother’s milk has been protecting infants forever...
