Coronavirus HKU 1 infection with bronchiolitis, pericardial effusion and acute respiratory failure in obese adult female.

Seven species of coronavirus cause of acute respiratory illness in humans. Coronavirus HKU 1 (CoV-HKU 1) was first described in 2005 in an adult patient with pneumonia in Hong Kong. Although it is a well-known respiratory tract pathogen, there is not much information about its role in hospitalized adults, especially in southern Europe. Here we describe a case of radiologically demonstrated CoV-HKU 1-related bronchiolitis with acute respiratory failure in an adult female without significant comorbidities except obesity.
