Good news guys:

"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."
"“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."
Looks like those people didnt get Reinfected.
"“The respiratory epithelial cell has a half-life of up to three months, and RNA virus in the cell can be detected with PCR testing one to two months after the elimination of the cell,” Oh said."
"The committee ruled out reactivation of COVID-19 as a reason for relapses and said there was little to no possibility that reinfections would occur due to antibodies that patients develop."
This means its still very likely you do infact gain immunity after being infected.
