**6. Other ENT related symptoms of COVID-19**

In patients without pneumonia, the COVID-19 clinic is similar to some diseases frequently encountered by ENT physicians in the outpatient clinic. COVID-19 can be confused with the flu or common cold in terms of initial symptoms, causing patients to apply to the ENT clinic in the foreground. There may be serous nasal discharge, hyperemic oropharynx, watery eyes and tearing. Since hoarseness is not among the symptoms mentioned, it may be thought that there is no cause of laryngitis or findings similar to laryngitis are not found on examination. Sore throat is a common symptom of COVID-19. Most of pharyngitis or sore throat is of viral origin and these pathogens are predominantly rhinovirus, influenza, adenovirus, coronavirus (previously isolated types) and parainfluenza virus [48].

Other human corona viruses are common cause of viral pharyngitis. Considering that, Sars-CoV-2 is likely to cause pharyngitis and/or similar clinical features.

Both possibilities should be kept in mind in a patient presenting with hyperemia in the oropharynx and difficulty swallowing. Unfortunately, in the current situation, definitive diagnosis distinction can only be made by laboratory testing. The rapid progression and sudden onset of the disease should be thought-provoking for COVID-19.

It should be kept in mind that COVID-19 can also cause rhinitis. It may have similar symptoms with allergic rhinitis. Although fatigue and weakness due to sleep disturbance in allergic rhinitis are reported; muscle pain, malaise and sore throat are not expected. Watery and red eyes may occur in both diseases, but itching in the eyes, palate and nose can be a guide for allergic diseases. Likewise, flu and cold are other common diseases that can be confused with COVID-19. While runny nose is more common in colds than other diseases, in influenza and Sars-CoV-2 infection dry cough is in the foreground.
