At least fourteen sailors aboard the USS Chief Executive UN agency had recovered from COVID-19 have tested positive for a second time, raising questions about immunity and whether or not folks will catch the coronavirus shortly once recuperating.
The sailor's UN agency "previously tested COVID positive and met rigorous recovery criteria have retested positive," a U.S. Pacific Fleet advocate the same in a very statement. The sailors square measure currently off the ship and square measure needed to isolate for a minimum of fourteen days.
Experts same the confusing check results do not essentially establish that an individual will become infected doubly — the positive results following negative checks could also be a quirk associated with the sort of test that was used.
Nearly all of the diagnostic tests for COVID-19 within the U.S. rummage around for snippets of the virus' ribonucleic acid, or order. (Another sort of diagnostic assay, referred to as Associate in Nursing matter check, appearance for proteins from the virus.)
But consistent with steering from the Centers for unwellness management and bar, "detection of infective agent ribonucleic acid doesn't essentially mean that infectious virus is gift." In alternative words, the check could also be memorizing a chunk of the infective agent ribonucleic acid that is been left behind, instead of a totally intact, infectious virus particle.
A second positive check when a negative result might mean the virus is solely taking its time going the body, doctors same, and is not any longer ready to infect others.
"It's potential that individuals may shed remnants of the virus for a few amount of your time. that does not mean something is wrong with them or that they're contagious," said Dr. William Schaffner, Associate in Nursing communicable disease professional at philanthropist University eye in Nashville.
