Among the main possibilities are re-infection, a relapse, or inconsistent tests, experts say. South Korea had reported 141 such cases as of Thursday, according to the Korea Centers for Disease Control and Prevention (KCDC). LIMITS OF TESTINGPatients in South Korea are considered clear of the virus when they have tested negative twice in a 48-hour period. This means that there still can be 2-5% of those cases that are detected false negative or false positive cases,” Kim said.
