Reports from South Korea say some patients had tested positive while being considered for discharge
The World Health Organization (WHO) has said it is looking into reports of some Covid-19 patients testing positive again after initially testing negative for the disease while being considered for discharge.
On Friday South Korean officials reported that 91 patients thought to have been cleared of the new coronavirus had tested positive again. Jeong Eun-kyeong, the director of the Korea Centers for Disease Control and Prevention, told a briefing that the virus may have been reactivated rather than the patients being re-infected.
The Geneva-based WHO, when asked about the report from Seoul, said in a brief statement: We are aware of these reports of individuals who have tested negative for Covid-19 using PCR (polymerase chain reaction) testing and then after some days testing positive again.
