"Dangerous mutant coronavirus strains may incubate in patients, such as
man sick with COVID-19 for 154 days

Among the 100 million people around the world who have battled coronavirus
infections, scientists are turning to the case of a 45-year-old COVID-19
patient in Boston to understand how the virus is able to outwit humans.

During his 154-day illness €” one of the longest on record €” the patients
body became a crucible of riotous viral mutation. He offered the world one
of the first sightings of a key mutation in the virus spike protein that
set off alarm bells when it was later found in strains in the United
Kingdom, South Africa and Brazil.

In the U.K. strain, the genetic change known as N501Y is thought to help
enhance the virus transmissibility by about 50%. In the South Africa
strain, it may reduce the effectiveness of COVID-19 vaccines and
treatments. Tests of its effect on the Brazil variant are still in
progress.

The Boston patient is now being viewed as an important harbinger of the
coronavirus ability to spin off new and more dangerous versions of
itself. Although he died over the summer, the medical file he left behind
is helping experts anticipate the emergence of new strains by focusing on
the role of a growing population of patients with compromised immune
systems who battle the virus for months.... "
