Singapore: According to the Centers for Korea Control and Disease Control and Prevention, the coronavirus could “reactivate” in people who are cured.
About 51 patients classified as having been cured in South Korea have again tested positive, the CDC said in a briefing on Monday. Rather than being re-infected, the virus may have been reactivated in these people because they tested positive again shortly after being released from quarantine, said Jeong Eun-kyeong, general manager Korean CDC.
“While we are putting more emphasis on reactivation as a possible cause, we are doing a thorough study of it,” said Jeong. “There have been many cases where a patient during treatment will be negative one day and positive another.”
A patient is considered fully recovered when two tests performed with an interval of 24 hours show negative results.
The Korean CDC will conduct an epidemiological investigation into the cases, said Jeong.
South Korea was one of the first countries to see a large-scale coronavirus outbreak, but the country has seen only 200 deaths and a new case count since its peak at 1189 on February 29. One of the largest screening programs in the world and a technological approach to locating infections has enabled Korea to contain its epidemic without locking up or shutting down businesses.
Fear of reinfection in cured patients is also increasing in China, where the virus first appeared in December after reports that some have tested positive – and even died of the disease – after being infected saying saying recovered and left the hospital. It is difficult to understand why this occurs, although some believe that the problem may lie in inconsistencies in the test results.
South Korea had 10,384 cases of the virus on Wednesday, including 6,776 released from hospital, according to data compiled by Johns Hopkins University and Bloomberg News.
Epidemiologists around the world are racing to find out more about the virus that causes Covid-19. The rapid global spread of the pathogen has recently resulted in a change of target to patients who contract the virus but have few or atypical symptoms. Korea has been at the forefront of monitoring these cases, which are of particular concern in China, where the epidemic is showing signs of control.
