Rhinovirus is linked to asthma exacerbations and chronic obstructive pulmonary disease exacerbations in adults. The severity and rates of rhinovirus acute respiratory illnesses (ARI) in adults are uncertain.
We determined rhinovirus-associated ARI rates in adults presenting for care in multiple settings and identified factors associated with rhinovirus detection.
This prospective, population-based cohort enrolled Tennessee residents ≥18 years old in the emergency department (ED), outpatient clinics, or hospitalized for ARI December 2008-May 2010. Nasal/throat swabs were collected and tested for rhinovirus and other viruses by RT-PCR. Rates of ED visits and hospitalizations were calculated and rhinovirus-positive and -negative patients were compared.
Among 2351 enrollees, rhinovirus was detected in 247 (11%). There were 7 rhinovirus-associated ED visits and 3 hospitalizations per 1000 adults annually. Patients with rhinovirus, compared to virus-negative ARI, were more likely to present with wheezing (odds ratio [OR] 1.7, 95% confidence interval [CI] 1.23-2.35, p<0.001), to be a current smoker (OR 2.31, CI 1.68-3.19) or live with a smoker (OR 1.72, CI 1.10-2.67), have a history of chronic respiratory disease (OR 1.61, CI 1.17-2.22), and were less likely to be hospitalized versus seen in the outpatient setting (OR 0.58, CI 0.41-0.83).
Rhinovirus is associated with a substantial number of ED visits and hospitalizations for ARI in adults. There may be modifiable factors that can reduce the likelihood of presenting with rhinovirus-associated ARI.
