It is because of Covid-19 that a majority of patients with respiratory infections lose their sense of smell, says a new study.
According to a study published in the journal Chemical Senses, the disease often results in both loss of taste and other senses in the mouth.
“This underlines how important it is to be aware of this symptom, as it may be the only symptom of the disease,” said Alexander Wieck Fjaeldstad, associate professor at Aarhus University, who also points out only about half of the patients with a loss of smell regained their sense of smell after 40 days.
For the study, a total of 23 nationalities and more than 4,500 Covid patients from around the world responded to the researchers’ questionnaire.
The results showed that the average loss of smell was 79.7 on a scale of 0 to 100 – indicating significant to complete sensory loss, the researcher said.
The loss of smell, sense of taste were also significantly reduced, to 69.0 on a scale of 0 to 100, just as the feeling of sensation remaining in the mouth was also reduced, this time to 37.3 on a scale of 0 -100.
“This shows that the loss of smell is specific to Covid-19, which is both relevant for recognizing infection, and because it indicates that smell is closely related to how SARS-CoV- 2 infects the body, “says the researcher. – IANS
