People who recover from COVID-19 but test positive for the virus
again days or weeks later are not shedding viral particles and are
not infectious, according to

infection with the new coronavirus, SARS-CoV-2, could

infection may fail to produce even short-lived immunity, allowing
patients to immediately become re-infected if they are exposed.

The new data from Korea should ease those concerns.
