Some authors report that rhinovirus accounts for up to 30% of cases of all virus-related pneumonia. Clinical studies show that rhinovirus is the second most frequently recognized agent associated with pneumonia and bronchiolitis in infants and young children. Rhinovirus infection is linked to asthma hospitalizations in both adults and children.

A study of 211 French children with rhinovirus infection revealed bronchiolitis or bronchitis in 25.6% and pneumonia in 6.2%, after cases of dual bacterial or viral infections were eliminated.

A study from the Netherlands demonstrated that rhinoviruses cause 32% of all lower respiratory tract infections with an identified pathogen in the elderly (> 60 y) symptomatic population. Rhinoviruses were identified more frequently than coronaviruses (17%) or influenza viruses (7%).
