Background: Mucosal coinfections with respiratory viruses and Streptococcus pneumoniae are common, but the role of rhinovirus infections in the development of invasive pneumococcal disease (IPD) in children has not been studied. Methods: During 1995 and 2007, we analyzed the association of IPD in children less than 5 years of age with respiratory virus epidemics by combining data from the National Infectious Disease Register, 3 prospective epidemiologic studies, and the database of the Department of Virology, University of Turku, Finland. Results: The mean IPD rate in children younger than 5 years of age in Finland was 2.9 cases per week (95% confidence interval inverted right perpendicularCIinverted left perpendicular, 2.5-3.3) during periods of high rhinovirus activity, and 1.4 (95% CI, 1.2-1.6) during periods of low rhinovirus activity (P < 0.001). The IPD rate correlated with the rhinovirus activity recorded at the Department of Virology (correlation coefficient, 0.23; P = 0.001) and in the epidemiologic studies (correlation coefficients, 0.28, 0.25, and 0.31). The IPD rate was moderately increased during periods of high respiratory syncytial virus activity (mean, 2.1 cases per week; 95% CI, 1.8-2.3) compared with periods of low respiratory syncytial virus activity (mean, 1.7; 95% CI, 1.6-1.9; P = 0.008). There were no differences in the IPD rate between the periods of high and low influenza activity. Conclusions: Rhinovirus circulation in the community had an association with IPD in children younger than 5 years of age. This study suggests that rhinovirus infection may be a contributor in the development of IPD in the population of young children.
