As the National Center for Biotechnology Information, at least the 88% of SARS-CoV-2 patients lose these senses and 80% of this population have reversible symptoms; 20% could have long-term sequelae, for which olfactory training would be required.
Despite the fact that data on the behavior of the virus remain scarce, the safe way to lose smell and taste are signs that the virus has begun to affect the body; in addition, it usually occurs in young patients.
What causes loss of smell and taste?
Contagion with coronavirus It is not the only cause of these problems, as they could also be caused by: common cold, allergic rhinitis, sinusitis, bronchitis and other respiratory problems, although there are certain differences.
Why the COVID-19 makes you lose smell and taste?
An investigation by the Harvard Medical School threw that virus directly affects the functioning of the nerve cells of the nasal cavity, known as glial cells, which allow communication between neural networks.
The attack suffered by the olfactory neurons makes the patient present anosmia, which is the total loss of smell and, in turn, of taste, so it is also difficult for the person to identify flavors.
