Fifty-one recovered COVID-19 patients in South Korea tested positive again for the virus after leaving quarantine, said health officials in the country this week.
A team of investigators were deployed to Daegu, the site of South Korea’s initial CCP virus outbreak earlier this year, to conduct an investigation into the test results.
“A few people recovered from the first time by their own immune system, but the meds they use are damaging their heart tissue, and when they get it the second time, the antibody doesn’t help but makes it worse, and they die a sudden death from heart failure,” the anonymous doctor told the Taiwan News.
However, some experts outside of China have said it’s not clear if patients are immune to reinfection from the virus.
Four seasonal coronaviruses that cause about 10 percent to 30 percent of common colds can cause reinfection, said researchers.
“Almost everybody walking around, if you were to test their blood right now, they would have some levels of antibody to the four different coronaviruses that are known,” Ann Falsey of the University of Rochester Medical Center told the public broadcaster.
On Monday, the KCDC reported less than 50 cases of the CCP virus, bringing the total of cases in the country to 10,284.
