In its first account of statewide antibody testing, the Florida Department of Health reported Friday that about 4.4 percent of more than 123,000 tested came back positive for signs of an infection, providing a snapshot of how the disease might be spreading.

But the report warns that the accuracy of commercial lab results included in the mix is not known and experts say even results from approved tests could have a high degree of inaccuracy.

Mounting evidence suggests the coronavirus is more common and less deadly than it first appeared.

The evidence comes from tests that detect antibodies to the coronavirus in a person's blood rather than the virus itself.

The tests are finding large numbers of people in the U.S. who were infected but never became seriously ill. And when these mild infections are included in coronavirus statistics, the virus appears less dangerous.

Monroe County Public Schools

Monroe County Public Schools have created a task force that’s focused on reopening schools in the fall. So far the county has 104 confirmed cases of COVID-19, which is significantly lower than other South Florida counties.

Sweden's controversial approach to fighting the coronavirus pandemic has so far failed to produce the expected results, and there are calls within the country for the government to change its strategy.

"We have a very vivid political debate," Karin Olofsdotter, Sweden's ambassador to the United States, told NPR. "I don't think people are protesting on the streets but ... there's a very big debate, if this [strategy] is the right thing to do or not, on Facebook and everywhere."

As South Florida cities begin to reopen, some are turning to antibody tests to keep tabs on the spread of COVID-19 among workers.

A nationwide analysis of COVID-19 data released this week shows broad discrepancies between what some states are reporting about testing for the novel coronavirus to the public, and what is being reported by the CDC. The analysis lists Florida as “the most extreme case” of testing discrepancies between what the state and the federal government are reporting.

As he toured the state earlier this month to promote his plans to reopen Florida, Gov. Ron DeSantis repeatedly touted testing for COVID-19 antibodies as a signal that immunity may be lurking, undetected, among the population.

To safely phase out social distancing measures, the U.S. needs more diagnostic testing for the coronavirus, experts say. But how much more?

The fastest test being used to diagnose people infected with the coronavirus appears to be the least accurate test now in common use, according to new research obtained by NPR.

Researchers at the Cleveland Clinic tested 239 specimens known to contain the coronavirus using five of the most commonly used coronavirus tests, including the Abbott ID NOW. The ID NOW has generated widespread excitement because it can produce results in less than 15 minutes.

Dozens of blood tests are rapidly coming on the market to identify people who have been exposed to the coronavirus by checking for antibodies against it.

The Food and Drug Administration doesn't set standards for these kinds of tests, but even those that meet the government's informal standard may produce many false answers and provide false assurances. The imperfect results could be a big disappointment to people who are looking toward these tests to help them return to something resembling a normal life.


Miami-Dade County and the University of Miami on Friday launched what they say is the largest community study yet to detect the spread and infection rate of the COVID-19 coronavirus.
