Guwahati: In early April, South Korea had announced that patients that recovered from COVID-19 infection have been tested positive for coronavirus again. But recent research at the Korean Centers for Disease Control and Prevention updated this information by stating that those patients who were tested positive again show no sign of virus transmission.
By the end of April, 263 similar cases were recorded in South Korea and even China also reported the same. The researchers examined 285 such cases and found that they do not spread any lingering infection as the virus samples collected from them couldn’t be grown in culture. This could point to just one result and it’s that the patients were shedding the dead virus particles aka the non-infectious particles.
In the blood tests of the patients who tested COVID-19 positive within 82 days after becoming infected, showcased clear signs of the presence of antibodies against the virus. The recent research also showcased that the PCR tests for COVID-19’s nucleic acid cannot differentiate between dead and viable virus particles.
Hence, South Korean authorities stated that people returning to work or school should no longer be required to test negative for the virus after they have already recovered from the virus (including the completion of their period of isolation).
The discoveries, announced late on Monday, are a good sign for areas hoping to open up as more patients recover from the novel coronavirus that has sickened 4.8 million individuals at the very least.
