“The impacts of the ongoing COVID-19 pandemic continue to be felt across the
world, but some consequences are more noticeable than others. New research
suggests a large proportion of people may have lost their sense of smell after
catching COVID-19, without even realizing it.
It's well known that getting COVID-19 can lead to smell blindness (anosmia) or
a partial loss of smell (hyposmia). In fact, it happens with a lot of viral
infections, as the viruses interfere with various cells and receptors in the
nasal passages. The sense of smell often comes back – but not always.
Here, researchers in the US wanted to take a closer look at the long-term
consequences of COVID-19 on our smelling capabilities.
They ran smell tests on 2,956 volunteers with a history of COVID-19 infections
and 569 who hadn't caught the virus. On average, the smell testing took place
671 days after participants had first been tested for COVID-19.
Of the COVID-19 group, 1,393 thought they had issues with smell, and tests
confirmed about 80 percent of them did. Surprisingly, the other 1,563 people in
that group didn't report any smell problems, but test results showed 66 percent
of them had hyposmia or anosmia after their COVID-19 infections.
"Our findings confirm that those with a history of COVID-19 may be especially
at risk for a weakened sense of smell, an issue that is already underrecognized
among the general population," says general internist Leora Horwitz, from the
New York University Grossman School of Medicine.”
