At first, we took SARS-CoV-2 virus into consideration as one of causes
of acute supraglottitis during COVID-19 pandemic, as Tysome et
al. indicated.1 However, in this case, the
laryngoscopic findings did not show the ulceration nor overlying
fibrinous exudate, which was seen in viral laryngitis,1, 2 but show inflammation and edema, and blood test
data was neutrophil predominance (85.5%), suggesting that the case was
not caused by virus, but bacteria, nervertheless during COVID-19
pandemic. After the judgement by us, the patient immediately received
intravenous antibiotics, and she fortunately recovered from the illness
without tracheostomy.
