Reports of patients recovering from corona after treatment are reported positive weeks later. Researchers say they cannot spread the infection. This claim has been made by researchers in South Korea. Scientists from Korea's Centers for Disease Control and Prevention conducted research on 285 Corona Survivors that were found positive after treatment.
Virus did not develop in lab
According to the researchers, the report that came positive after treatment in patients may be due to coronavirus dead particles present in the body. It does not spread infection to anyone. A sample of the virus was taken from such patients. The lab showed no development in it and proved that there are non-degradable particles.
PCR test of 285 samples done
The researchers say a PCR test was performed to confirm the nucleic acid of the coronavirus in a sample of 285 patients. Through the investigation, an attempt was made to understand whether the virus is alive or has some part in the patients coming back again. Research has proved that the virus is not activated to spread the infection in positive patients.
Changed South Korea guidelines
South Korean officials say that according to the changed guidelines, now recovered people will not be required to show negative test reports before joining school or office. According to Korea's Centers for Disease Control and Prevention (KCDC), people no longer need to undergo any type of test after isolation.
Report positive again in 82 days
According to the government health agency, reports of some patients may return positive up to 82 days after infection. In almost all cases, corona survival antibodies develop virus-fighting antibodies. This has also been confirmed in blood tests.
