Coronavirus: Korea CDC says those who recover AREN'T infectious

This evidence from South Korea also suggested that recovered COVID-19 patients pose no risk in spreading coronavirus as social distancing measures are relaxed.

Around 440,000 final-year students, who will in December take the university entrance exam that is crucial in the education-obsessed country, are the first to return to schools, with other years following in stages over the next several weeks.

After an unprecedented five-month break, South Korean students are returning to their classrooms as government health officials declared that the country may have avoided a second wave of infections.

Scientists from the Korean Centers for Disease Control and Prevention studied 285 covid-19 survivors who had tested positive for the coronavirus after their illness had apparently resolved, as indicated by a previous negative test result.

In addition, the researchers have also discovered that they are forming antibodies that could prevent them from falling ill from the SARS-CoV-2 or the novel coronavirus.


The new group infection began when a nurse working at the hospital's cardiothoracic operating rooms tested positive on Monday.

Another positive sign from the findings is that nearly all of the cases for which blood cases were taken had antibodies against the virus, which lends credence to the theory that people who were previously infected have built up some form of protection.

With that, the researchers believe that these people were shedding either dead or noninfectious particles.

"There have been no secondary infections from people who came in contact with the relapsed patients so far", said Yoon Tae-ho, a senior health ministry official. "We have not found evidence that those cases are contagious".

According to the Herald, as of Friday, South Korea had 447 patients who tested positive again after recovering.


Instead, these people will be referred to as "PCR re-detected after discharge from isolation".

Unlike in the U.S., South Korea's academic year starts in March, but students never returned to school after their winter break as the nation confirmed its first COVID-19 infection in late January and then saw a spike in cases - peaking at near 1,000 a day - in February.

"Under the new protocols, no additional tests are required for cases that have been discharged from isolation", researchers said.

They also don't know how long immunity will last.

'There is now no evidence that people who have recovered from COVID-19 and have antibodies are protected from a second infection'.
