First COVID-19 mortality case in Taiwan with bacterial co-infection by national surveillance of critically ill patients with influenza-negative pneumonia.

A 63-year-old diabetic smoker with alcoholism was the first mortality case of coronavirus disease 2019 (COVID-19) in Taiwan. As concurrently infected with Klebsiella pneumoniae and subsequently with Klebsiella aerogenes, he was exposed by a national survey of patients with critically influenza-negative pneumonia. We recommend COVID-19 screening for patients with severe flu-like syndrome and protecting health-care workers from being infected.
