The results of a new scientific study found that the sense of smell disappears mostly in infected patients after about the third day of infection.

The study, which was published in the scientific journal (Otolaryngology-Head and Neck Surgery), added that the injury may be associated with a loss of taste as well in the same period, that is, after the third day of the injury.

According to the researchers behind the study, these findings should help identify patients who may respond to antiviral medications.

One of the researchers in the study, Dr. (Ahmad Sedaghat), said: “The relationship between the loss of the sense of smell and infection with the emerging corona virus would help determine the period of infection of the patient with the virus, which is during the first week of it.”

In order to reach these results, researchers identified symptoms associated with infection of 103 people in Switzerland, who were diagnosed with the emerging coronavirus within six weeks.

They noted that approximately 61% of patients experienced a decrease or absence, and according to the study, this symptom may appear between the third or fourth day of infection approximately.

The researchers reported that the decreased sense of smell due to infection with the virus may be clearer in young people and women, and that the severity of this symptom is associated with the severity of other symptoms as well.
