Preliminary findings from the “South Korean Center for Disease Control” suggests patients who recover from COVID19 and then test positive for the virus again are not infectious and are not spreading the virus to others and could have the antibodies that prevent them from falling sick again. Scientists studied 285 patients who had retested positive after recovering from the coronavirus.

447 South Koreans tested positive a second time, but those virus traces appeared to be dead, not alive.

Officials and researched are greeting the new finding in optimism. It means the officials are no longer required the recovered COVID patients to test negative before being released from quarantine.

Having the antibodies doesn’t automatically mean immunity, but the South Korean report is further evidence that people who have recovered and do have antibodies may return to work without the fear of infecting others.

The South Korean government said that it would no longer consider a person contagious if they already have recovered from coronavirus. It has also ruled out the need for test of the virus once someone has recovered and are out of quarantine, in order to travel again or return to work or school.

“Under the new protocols, no additional tests are required for cases that have been discharged from isolation,” the Korean CDC said in a report. The agency said it will now refer to “re-positive” cases as “PCR re-detected after discharge from isolation.”
