Viral Bronchiolo-Alveolitis From Coronavirus OC43 and Rhinovirus-Simulating SARS-CoV-2 Infection.

Viruses are the most common cause of acute lower respiratory tract. The respiratory syncytial virus infection is most commonly associated with viral bronchiolitis. Rhinovirus and coronavirus OC43 are less frequently responsible for lower respiratory tract infections. The virological spectrum has expanded greatly owing to the development of molecular biology techniques. We report the clinical case of a four-month-old infant who presented with acute lower respiratory infection with coronavirus OC43 (HCoV-OC43) and rhinovirus complicated by a particularly extensive spontaneous pneumomediastinum.
