U.S. doctors report early warning signs of new coronavirus infection: loss of sense of smell or taste disorder

Symptoms of COVID-19 infection may be mild and nonspecific, including sore throat, dry cough and shortness of breath,media BGR reported. These are the symptoms that many different types of respiratory diseases may accompany and are not necessarily indicators of specific types of infection. But a new report from doctors across the United States shows that in confirmed cases of new coronavirus, with some kind of regularity, there appears to be a unique symptom: loss of sense of smell.

According to these new reports, many patients reported loss of sense of smell, and they eventually tested positive for COVID-19. To a lesser extent, changes in taste in patients with the new coronavirus have also been reported.

U.S. doctors report early warning signs of new coronavirus infection: loss of sense of smell or taste disorder

It is not clear why these symptoms are common in patients with COVID-19, but it has been shown to be beneficial to doctors and their patients. An early warning signal that is known to be not present in patients with the common cold or flu may be an important difference for COVID-19.

Doctors at the American Academy of Ear, Nose and Throat Sciences issued the following statement about the findings:

Evidence quickly gathered from around the world suggests that loss of smell and taste disorders are important symptoms associated with the COVID-19 pandemic. In particular, olfactory loss was found in patients who eventually tested positive for the new coronavirus without any other symptoms. We recommend adding these symptoms to the list of screening tools for possible COVID-19 infections.  In the absence of other respiratory diseases (e.g. reticitis, acute nasal-sinusitis or chronic nasal-sinusitis), if there is loss of smell, loss of smell and taste disorders, doctors should be alerted to the possibility of COVID-19 infection and should be carefully considered for self-isolation and testing of these persons.

These unique early symptoms have been observed in many COVID-19 cases in Korea, China and Europe.

“There is good evidence from South Korea, China, and Italy that a large number of COVID-19 infection patients have experienced loss of sense of smell/smell,” ENTUK said in a statement. “Two-thirds of confirmed cases in Germany are reported to have loss of smell. Tests were more common in South Korea, where in other cases, 30 percent of patients who tested positive in mild cases were mainly characterized by loss of sense of smell. “

Looking ahead, doctors believe that loss of smell or taste should be increased in early screening in order to make it easier to identify positive cases at an early stage.
