SEOUL: Patients who tested positive for novel coronavirus after recovering from their first bout of the illness appeared to be far less infectious the second time round, South Korea’s health authorities said on Wednesday.
While the trend in new cases in the country remained downward, the Korea Centers for Disease Control and Prevention (KCDC) has begun investigating a growing number of people testing positive after recovering.
More than 180 such cases have been reported so far in South Korea but none were found to have infected anyone else.
The medical authorities in South Korea initially conduct polymerase chain reaction (PCR) tests on suspected cases.
But investigating people who appear to suffer a relapse after recovering from COVID-19, the KCDC takes cultures of the virus, a process that takes more than two weeks before reliable results become evident.
So far, culture tests are underway for 39 cases, but all six completed so far have been negative.
“That means the virus in the relapse cases have little to no infectiousness,” KCDC director Jeong Eun-kyeong told a briefing.
Jeong dismissed the idea of replacing PCR tests with culture tests to determine whether a patient has fully recovered, due to the amount of time and resources that they require.
The KCDC said it is still examining why some patients test positive again after recovering.
Among the main possibilities are re-infection, a relapse, or inconsistent tests, experts say, and Jeong has said the virus may have been “reactivated” rather than the patients being re-infected.
The KCDC reported on Wednesday 11 new coronavirus cases, taking the total infections to 10,694. The daily tally of new cases has been hovering around 10 for the past five days.
The death toll stands at 238.
After grappling with the first major outbreak outside China, South Korea has largely managed to bring the outbreak under control without major disruptions thanks to a massive testing campaign and intensive contact tracing.

Kremlin says won’t share ‘specifics’ of Putin, Trump phone call on Iran war
DUBAI: The Kremlin said on Wednesday that it will not disclose the specific proposals by Russian President Vladimir Putin on the current Middle East war which came during an earlier phone call with US President Donald Trump.
During a presser, Kremlin spokesman Dmitry Peskov told reporters that Russia will not disclose the “specifics” of the Russian president’s proposals to Trump.
Putin held a phone call with Trump on Monday where they discussed the Ukraine and Iran wars.
Trump hailed the conversation as “positive.”
“He wants to be helpful” on the Middle East, Trump said of Putin.
Russian presidential aide Yury Ushakov told reporters later that day that Putin had a roughly one-hour telephone conversation with Trump at the request of the US side. The two leaders had not spoken over the phone since late December of last year.
Separately, Russia said it is constantly in touch with the Iranian leadership and willing to contribute to efforts to stabilize the region.
“Here I can only say that we are in constant contact with the Iranian side and with the Iranian leadership.”
“As President (Vladimir) Putin has said, Russia is always ready to do what it can to restore peace and stability in the region.”
