Background
COVID-19 related public health and social measures (PHSMs) worldwide have influenced respiratory virus epidemiology. In Hong Kong, paediatric hospitalisations associated with non-COVID-19 respiratory viruses declined in 2020. As PHSMs eased, rhinoviruses/enteroviruses became the primary detected respiratory viruses. This study examines the genetic diversity in resurgent human rhinovirus (HRV) cases.
