Coronavirus: Scientists conclude people cannot be infected twice
A number of reported cases of coronavirus patients relapsing after
overcoming the disease were actually due to testing failures, South
Korean scientists say.
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.
A total of 277 patients in the country 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.
However, genetic analyses of the virus have not found any substantial
changes which would effectively disguise it from the immune system.
