WATCH: Reports show those who tested positive a second time for COVID-19 aren't contagious anymore

MEMPHIS, Tenn. — A new study said patients who tested positive for the coronavirus again, after recovering, are no longer contagious, according to the Korean Center for Disease Control.

If you test positive for COVID-19 and recover, you may test positive for a second time but that doesn’t necessarily mean you still have the virus, according to KCDC.

The KCDC study said people who recovered from the virus tested positive because the test confused dead viral matter for an active case of COVID-19.

“The test doesn’t look for the virus that can infect you from them,” said Dr. Stephen Threlkeld. “It looks for tiny pieces of RNA that would be part of the virus”

Dr. Threlkeld is an infectious disease specialist at Baptist Hospital in Memphis.

He said the results from this study are very encouraging.

In the study, the KCDC examined 400 people who recovered from the coronavirus

285 of them retested positive for the coronavirus after recovering.

However, when researchers examined the patient's close contacts, those people did not test positive for the infection and because of this, the KCDC decided COVID-19 survivors will no longer need to be quarantined for two weeks after they are released from the hospital.

"For a long time, apparently we will still have little pieces of debris that the test will go in and say there is my piece of RNA, we have virus here, when really all we know are there are pieces of RNA and those don’t do anything,” he said.

And now the question remains, how long will people have immunity?

“With the common cold, coronavirus its very variable,” Dr. Threlkeld said. “People can have decent immunity. You are not likely to get it again for a period of months, but by next year or two or three years you very likely can get it again”
