Concerns that people could recatch the virus in a short period of time after they had it have proved wrong…
It seems…..Once you get it?
Your body develops an immunity….
It is unknown how strong , or how long it lasts…
But you do NOT recatch the virus right after you get over it…
The South Korea test result’s where false positives for those retested after they had the virus…The tests cannot separate dead virus cells from live ones…
As time goes by?
More and more factual things will become known about this virus…
This IS seems to be good news for the millions of people around the world have had the virus and may not even know they had it…..
South Korea’s infectious disease experts said Thursday that dead virus fragments were the likely cause of over 260 people here testing positive again for the novel coronavirus days and even weeks after marking full recoveries.
Oh Myoung-don, who leads the central clinical committee for emerging disease control, said the committee members found little reason to believe that those cases could be COVID-19 reinfections or reactivations, which would have made global efforts to contain the virus much more daunting.
“The tests detected the ribonucleic acid of the dead virus,” said Oh, a Seoul National University hospital doctor, at a press conference Thursday held at the National Medical Center.
He went on to explain that in PCR tests, or polymerase chain reaction tests, used for COVID-19 diagnosis, genetic materials of the virus amplify during testing, whether it is from a live virus or just from fragments of dead virus cells that can take months to clear from recovered patients.
The PCR tests cannot distinguish whether the virus is alive or dead, he added, and this can lead to false positives….
