The relationship between RSV (human respiratory syncytial virus) infections and invasive infections or pneumonia caused by Streptococcus pneumoniae has been observed epidemiologically for several years. Few fundamental data exist to support the epidemiological relationship. This study will investigate the proportion of pneumococcal carriage in RSV-infected infants and noninfected infants (proportion, serotype profile).
Infants aged 6 months to 18 months inclusive

No history of bronchiolitis
Chronic respiratory illness
