Though viral respiratory tract infections are reported triggers for exacerbations, information on these infections with asthma is sparse in Caribbean territories. We examined the distribution of respiratory viruses and their association with seasons in acute and stable asthmatic children in Trinidad.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods<\/jats:title>\n            <jats:p>In a cross-sectional study of 70 wheezing children attending the emergency department for nebulisation and 80 stable control subjects (2 to 16 yr of age) in the asthma clinic, nasal specimens were collected during the dry (<jats:italic>n<\/jats:italic> = 38, January to May) and rainy (<jats:italic>n<\/jats:italic> = 112, June to December) seasons. A multitarget, sensitive, specific high-throughput Respiratory MultiCode assay tested for respiratory-virus sequences for eight distinct groups: human rhinovirus, respiratory syncytial virus, parainfluenza virus, influenza virus, metapneumovirus, adenovirus, coronavirus, and enterovirus.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>Wheezing children had a higher [\u03c7<jats:sup>2<\/jats:sup> = 5.561, <jats:italic>p<\/jats:italic> = 0.018] prevalence of respiratory viruses compared with stabilized asthmatics (34.3% (24) versus (vs.) 17.5% (14)). Acute asthmatics were thrice as likely to be infected with a respiratory virus (OR = 2.5, 95% CI = 1.2 \u2013 5.3). The predominant pathogens detected in acute versus stable asthmatics were the rhinovirus (RV) (<jats:italic>n<\/jats:italic> = 18, 25.7% vs. <jats:italic>n<\/jats:italic> = 7, 8.8%; <jats:italic>p<\/jats:italic> = 0.005), respiratory syncytial virus B (RSV B) (<jats:italic>n<\/jats:italic> = 2, 2.9% vs. <jats:italic>n<\/jats:italic> = 4, 5.0%), and enterovirus (<jats:italic>n<\/jats:italic> = 1, 1.4% vs. <jats:italic>n<\/jats:italic> = 2, 2.5%). Strong odds for rhinoviral infection were observed among nebulised children compared with stable asthmatics (<jats:italic>p<\/jats:italic> = 0.005, OR = 3.6, 95% CI = 1.4 \u2013 9.3,). RV was prevalent throughout the year (Dry, <jats:italic>n<\/jats:italic> = 6, 15.8%; Rainy, <jats:italic>n<\/jats:italic> = 19, 17.0%) and without seasonal association [\u03c7<jats:sup>2<\/jats:sup> = 0.028, <jats:italic>p<\/jats:italic> = 0.867]. However it was the most frequently detected virus [Dry = 6\/10, (60.0%); Rainy = 19\/28, (67.9%)] in both seasons.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>Emergent wheezing illnesses during childhood can be linked to infection with rhinovirus in Trinidad's tropical environment.
