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.
"So this is an extraordinary individual," Li says.
So extraordinary in fact, that this man's case is offering scientists surprising clues about where the new coronavirus virus variants emerged, and why they're causing explosive outbreaks on three continents.
To be clear here, the man wasn't what doctors call a "long hauler," or a person who clears a COVID infection and then continues to have health problems for months. This man had living, growing virus in body for five months, Li says. The same infection lasted for five months.

The UCSC SARS-CoV-2 Genome Browser
The UCSC SARS-CoV-2 Genome Browser ( https://genome.ucsc.edu/covid19.html ) is an adaptation of our popular genome-browser visualization tool for this virus, containing many annotation tracks and new features, including conservation with similar viruses, immune epitopes, RT–PCR and sequencing primers and CRISPR guides. We invite all investigators to contribute to this resource to accelerate research and development activities globally.
