The earliest and most inconspicuous symptom of COVID-19 named – Rambler / doctor

A group of scientists from Spain managed to find out that in a patient with coronavirus, one of the symptoms occurs earlier than other manifestations of the infection. Details of the study are available on the medRxiv preprint site.

According to experts, a patient with a coronavirus has dryness and discomfort in the nose even before he loses the ability to smell and taste food.

A change or complete loss of smell and taste is noted by about 80% of patients with a positive test for COVID-19. Scientists believe that the loss of smell in coronavirus is due to the fact that goblet cells stop secreting mucus, which is necessary for the molecules of odorants (substances responsible for odors). And they simply cannot stick to the right receptors.
