Researchers at the South Korean centre for disease control and prevention (CDC) now say it is impossible for the Covid-19 virus to reactivate in human bodies, Sky News reported.
The patients reportedly relapsing after overcoming the disease were actually due to testing failures, scientists said.
A total of 277 patients in the South Korea were believed to have fallen ill for a second time, as had patients in China and Japan.
This prompted concerns that the virus could be mutating so quickly that people were not necessarily immune to catching it again.
Genetic analyses of the virus however, did not find any substantial changes which would effectively disguise it from the immune system. Partially as a result of these reports, the World Health Organisation warned governments against using so-called “immunity passports” to allow people to return to work simply because they have antibodies for the virus.
