Where Did The Coronavirus Variants Come From?
Scientists are looking at a possible link between the mutations in the U.K. and South Africa — and those in immunocompromised patients who are infected with COVID-19.
Back in the spring last year, a 45-year-old man went to the Brigham and Women's Hospital in Boston because of a COVID-19 infection. Doctors treated him with steroids and discharged him five days later.
But the COVID infection never went away — for 154 days. "He was readmitted to the hospital several times over the subsequent five months for recurrence of his COVID-19 infection and severe pneumonia," says infectious disease doctor Jonathan Li at Harvard Medical School who helped to treat the man.
