Phylogenetic Patterns of Human Respiratory Picornavirus Species, Including the Newly Identified Group C Rhinoviruses, during a 1-Year Surveillance of a Hospitalized Patient Population in Italy

Human rhinovirus species C (HRV-C) was the second most common HRV species detected in hospitalized patients in Italy with acute respiratory disease during a 1-year surveillance period. Sequencing of the picornavirus VP4/VP2 region allowed molecular typing of HRV-A and HRV-B and provisional typing of HRV-C.
