Scientists have discovered why patients with COVID-19 lose their sense of smell

Ученые выяснили, почему пациенты с COVID-19 теряют обоняние

An international group of scientists under the guidance of neuroscientists from Harvard medical school found out why the coronavirus for some time, lost sense of smell.

Earlier short-term loss of smell (anosmia) was recognized as the main and the earliest neurological symptom coronavirus infection. The experts believed that the virus infects cells in the upper part of the nasal cavity, so the neurons do not transmit signals about odors to the brain.

A new study published in the journal Science Advances on July 24, denied the above mentioned assumption.

“Changes in the smell of patients caused by a new coronavirus, are not associated with direct infection of neurons, and effects on supporting cells,” said one of the study’s authors Sandeep Robert Datta.

He explained that the discovery has given hope that in most cases, the coronavirus does not lead to serious damage to the nervous networks. That is, after recovery, the neurons will not change, and a complete loss of smell, man is not threatened.
