COVID-19: 51 Discharged South -Korean Patients Test Positive Again

Korea Centers for Disease Control and Prevention (KCDC) said on  Monday that 51 people from Daegu and the surrounding North Gyeongsang Province tested positive for COVID-19 a “relatively short time” after they were released.

The virus likely was reactivated, said KCDC Director-General Jeong Eun-kyeong, instead of the people being reinfected once they left, South Korea’s Yonhap news agency reported.
The group of people came from the epicentre  of South Korea’s coronavirus outbreak in Daegu.

Health authorities told Yonhap news agency that a team of investigators had been sent to Daegu to conduct an epidemiological investigation into the cases.

In March, the South China Morning Post reported that doctors in Wuhan, China – where the virus emerged – said that as many as 10 percent of coronavirus patients had tested positive again after being discharged from the hospital.

Wang Wei, the president of Tongji Hospital where the first COVID-19 case was identified, told state broadcaster CCTV that those who tested positive did not have any symptoms and none of their close contacts had been infected.

Scientists ponder whether it’s possible for people to develop immunity to COVID-19 after the initial infection.

“We need a large-scale epidemiological study to guide our disease surveillance and prevention works,” he was quoted as saying.

The news out of South Korea came as officials are now considering using electronic wristbands to monitor the growing number of people placed under self-quarantine to slow the spread of COVID-19 as 47 new cases were reported.

South Korea has been enforcing 14-day quarantines on all passengers arriving from overseas to stem a rise in imported infections.

More than 46,500 people were under self-quarantine as of Monday evening, including 38,400 who recently arrived from abroad, according to Lee Byeong-cheol, an official from the Ministry of the Interior and Safety. That number could grow to 80,000 or 90,000.

Health Ministry official Yoon Tae-ho on Tuesday acknowledged that wristbands would come with privacy concerns. It wasn’t clear how South Korea would enforce the wristbands, but the country has previously warned of a crackdown on those who disobey quarantines.

Yoon said such devices were among several measures discussed as “practical and effective ways” to monitor people isolated at homes and facilities.
