One of the novel coronavirus puzzles that scientists are still trying to figure out concerns an unexpected phenomenon that has been observed in many countries affected by the pandemic. Some COVID-19 patients who have been declared cured after testing negative twice in 24 hours end up relapsing, if that’s even the proper way to describe it. They test positive again at a later point in time, and there’s no clear answer as to why that happens. Also, it’s unclear whether these patients are contagious and can infect others, but some of them do show mild COVID-19 symptoms upon the second reinfection. The newest data coming from South Korea, a country that has the local COVID-19 epidemic under control, shows a growing number of people who are testing positive a second time.
