South Korean health jurisdictions raised new worries regarding the novel coronavirus following reporting last month, which dozens of individuals who had recovered from the disease later tested positive.
The findings indicated that some men and women who lived COVID-19 could eventually become reinfected with the virus, which causes it to be possibly complicating attempts to raise quarantine constraints and also to generate a vaccine.
However, after weeks of study, they say that these evaluation results seem to be”false positives” due to lingering — but probably not contagious — pieces of this virus.
What is occurring?
As more and more South Koreans have been released in therapy for COVID-19, police found a troubling trend. Some treated patients were testing positive.
While officials analyzed several potential explanations, for example, reinfection of individuals, or reactivation of the virus, an expert panel convened by the authorities concluded a week that the most probable reason was that the evaluations are coming”false positives.”

South Korea utilizes reverse transcription-polymerase chain reaction (RT-PCR) evaluations, which find that the coronavirus’s hereditary material.
The RT-PCR procedure can quickly return effects and is thought to be the most accurate method to learn if a patient is infected with the coronavirus.
But in a few instances, the tests could detect aged particles of this virus, which might not pose a substantial danger to the individual or other people, stated Seol Dai-wu, a master in disease development at Seoul’s Chung-Ang University.
“The RT-PCR machine cannot differentiate an infectious viral particle with a non-infectious virus particle, even since the evaluation only finds any viral element,” Seol explained.
This so-called false-positive effect is probably behind the instances of recovered patients testing positive, the KCDC states.
Police are still collecting evidence to support their notion that the particles have been out of”dead” virus tissues, KCDC manager Jeong Eun-Kyong stated on Wednesday.
The sufferers were retested later. They exhibited new respiratory ailments or were chosen for retesting by police.
More significant than half of these retested by mid-April was demonstrating symptoms, as stated by the KCDC. However, police now say it’s not likely that those signs were being brought on by the virus.”
Are the sufferers infectious?
Patients who tested positive for your brand new coronavirus after recovering in COVID-19 don’t seem to be infectious.
The KCDC hasn’t found one instance in which such sufferers had passed on the coronavirus to a different individual, Jeong said.
When exploring people who seem to endure a relapse of symptoms after recovering in COVID-19, the KCDC takes civilizations of this virus. This procedure takes two or more weeks before dependable effects become evident.
At least 79 are processed.
This means it doesn’t result in chronic infection, and odds of this reactivating are extremely reduced, he stated in a briefing a week.
Police will also be conducting tests to discover the existence of any antibodies which might have grown to combat the virus, also are monitoring and testing individuals who came into contact with those sufferers.
