The #coronavirus can #mutate swiftly in one person’s body

Belgium, Coronavirus, Europe, Reinfection

The new coronavirus resurged again and again in the body of an infected man, eventually killing him while showing evidence of fast-paced evolution.

Manuela Cernadas and Jonathan Li at Brigham and Women’s Hospital in Boston, Massachusetts, and their colleagues followed the course of COVID-19 in a 45-year-old man with a long-standing autoimmune disorder, who was on a medication regimen that included powerful immunosuppressants

Roughly 40 days after the man first tested positive for SARS-CoV-2, follow-up tests indicated that the virus was dwindling — but it surged back, despite antiviral treatment.

The man’s infection subsided and then returned twice more before he died, five months after his first COVID-19 diagnosis. Genomic analysis showed that the man had not been infected multiple times. Instead, the virus had lingered and quickly mutated in his body.
