Patients who test positive for Covid-19 weeks after recovery aren't infectious

Patients who test positive for Covid-19 weeks after recovery aren't infectious”

Of the 790 people that about 285 "re-infected" coronavirus patients came into contact with, none were found to be infected with the virus.

According to Bloomberg, which first reported the news, the virus samples collected from the patients could not be grown in culture, which indicates the patients were either getting rid of non-infectious or dead virus particles.

The 18-year-old students were confirmed positive for the virus after visiting a karaoke establishment that had been visited earlier this month by another student connected with an educator in Incheon, who is believed to be the initial source of infection. Moreover, a PCR test can not distinguish between dead and active virus particles. The virus was isolated to be cultured, and negative results were returned in all cases, according to the KCDC. "We have not found evidence that those cases are contagious".

Because of the study's results, South Korean health officials will no longer consider people infectious after they recover from COVID-19.

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

But based on the new findings, experts recommended changing the description of the cases from "re-positive" to "PCR re-detected after discharge from isolation".

The report also found that nearly all of the 285 patients had antibodies, which provides more evidence that antibodies provide protection against the virus.

Health and education officials had anxious that a new cluster infections linked to nightclubs in Seoul earlier this month could once again jeopardize plans to reopen schools, but they concluded the latest outbreak appears under control.

It comes as deputy chief scientific adviser, Professor Dame Angela McLean, said she would draw "particular lessons" from South Korea when asked about what the United Kingdom has learnt from overseas.

One idea has been to issue "immunity passports" or "risk-free certificates" to people who were infected but later tested negative.

"Ryu Dae-hwan, secretary general of the Korea Baseball Organization (KBO), said the league is in "close coordination" with the sports ministry and public health officials" to determine when fans will be allowed to attend games again. "But we can't rule out the possibility that they could have been exposed to the virus through a different route", Jung said.
