One of the key symptoms of COVID-19, doctors call the loss of smell and taste in the patient. However, recent studies have shown that such violations also indicate a reliable immune response of the body to coronavirus infection..


The discomfort associated with the loss of taste and smell associated with COVID-19 has been experienced by many patients. They were identified as key symptoms of the SARS-CoV-2 coronavirus in 40-60% of infections.

A group of scientists at Columbia University studied this phenomenon more carefully and concluded that the violation of smell and taste is caused by the body’s immune response to infection. Moreover, these signs indicate a strong immunity of the patient. The doctors spoke about the progress of their study in an article published in the publication PLOS ONE.

Formerly online edition “Teacher’s newspaper” toldthat the pronounced aromas of flowers, spices and perfumes can return smells to people who have recovered from COVID-19.
