In South Korea, health officials are trying to solve a mystery: why 163 people who recovered from coronavirus have retested positive, according to the Korea Centers for Disease Control and Prevention (KCDC).
The same has been recorded in China, where some coronavirus patients tested positive after seeming to recover, although there are no official figures.That raises the question: can you get reinfected with coronavirus?
In South Korea, the proportion of cases that retest positive is low — of the 7,829 people who have recovered from coronavirus there, 2.1% retested positive, the KCDC said Friday. It is not clear how many of the people who have recovered have been tested again.
But patients retesting positive is still a concern around the world, including in countries like South Korea where authorities appear to have brought the outbreak under control.
