Abstract
|
|
|
The world has been facing a tremendous threat for more than 1 year by coronavirus disease2019 (COVID-19). Because of the ongoing pandemic of COVID-19, it is necessary to be awareof the characteristics and symptoms of COVID-19 in order to prevent the COVID-19 spread.
Common symptoms of COVID-19 include fever, cough, shortness of breath, headache andvarious types of pneumonia. Recently, smell loss has been extensively reported in COVID-19patients. They experience this before other general symptoms or smell loss can be their onlysymptom. These types of patients may be neglected and a potential source for viral spread.
Thus, screening tests of COVID-19 should be considered if patients have smell loss withoutany other nasal symptoms. Even though the recovery rate of smell loss in COVID-19 is relativelyhigh, there are unmet needs for further studies including the mechanism of olfactorydysfunction, proper treatment and long-term recovery in COVID-19.
