Harvard researchers discover why COVD-19 causes loss of smell

Harvard researchers discover why COVD-19 causes loss of smell

Loss of taste and smell were added to the United Kingdom government's official list of symptoms for COVID-19 in May.

The first study included 100 coronavirus patients from the University Hospital Frankfurt COVID-19 Registry.

Scientists say they have discovered why coronavirus causes people to lose their sense of smell.

According to researchers at Harvard Medical School identified which cell types used for smelling are the most vulnerable to a COVID-19 infection.

However, in the new study-which was published Friday in Science Advances-the researchers found that those neurons were largely unaffected by the coronavirus, and that the virus "is not actually capable of attacking the neurons that live in your nose", Datta said.

In an effort to better understand why this particular symptom is so common among COVID-19 patients, an worldwide team of researchers led by neuroscientists at Harvard Medical School (HMS) was able to identify the olfactory cell types in the upper nasal cavity most vulnerable to infection by SARS-CoV-2, the virus that causes COVID-19.

The immune systems of some people who have not been exposed to the novel coronavirus could have some familiarity with the pathogen - possibly helping to reduce the severity of illness if that person does get COVID-19, a new study suggests. This study found greater amounts of viral nucleic acid - the genetic codes for proteins to produce new viruses - in children younger than 5 years. At that stage, however, very little was known about how and why the virus affects an infected person's sense of smell.

CAS reveals Man City ignored UEFA investigation, but did not breach FFP
Manchester City beat new champions Liverpool 4-0 in their Premier League match on 2 July 2020 at the Etihad stadium. The leaked documents included club emails which referred to money being "routed" through sponsors.

Based on the evolutionary relationship among the 68 coronaviruses, the researchers estimate that the branch of the virus family tree that leads to SARS-CoV-2 diverged from related viruses between 1948 and 1982.

The findings suggest that disease of nonneuronal cell types might be responsible for anosmia from COVID-19 patients and also help inform attempts to comprehend the development of the disease improved.

For most of the patients it has been a temporary symptom though, lasting just several weeks, even in the absence of stuffy nose, with a smell function returning to patients in full after recovery.

"We know the virus is making its way into the heart muscle, and seems to cause an inflammatory response that we don't fully understand yet", Dr. Matthew Belford, an interventional cardiologist at Wake Forest Baptist Health in Winston-Salem, North Carolina, said.

"I think it's good news, because once the infection clears, olfactory neurons don't appear to need to be replaced or rebuilt from scratch".

But, he added, "we need more data and a better understanding of the underlying mechanisms to confirm this conclusion".

"It can have serious psychological effects and may be a significant public health issue if we have an increasing population with permanent loss of smell".
