Abstract
Human rhinovirus (HRV) infections are generally referred to as the common cold, and are the main cause of mild symptoms. HRV is less frequently implicated in the development of severe respiratory infections. This study reports a nosocomial outbreak of bronchitis and pneumonia caused by HRV in a hospital during the COVID-19 epidemic in September 2022 in Gunma Prefecture, Japan. The patient continued to be symptomatic for nine days. During this outbreak, all 15 residents displayed respiratory symptoms. HRV-A was detected in 12 of the 12 samples, and phylogenetic analysis classified the strain as HRV-A type 61. HRV, COVID-19, and other respiratory infections cannot be differentiated based solely on clinical symptoms. A surveillance system to monitor them is thus needed.
