The results of PCR analysis of combined nasopharyngeal and throat swabs for 13 different viruses were positive in 63% of patients with asthma exacerbation in the 1-year study. We disagree with the low virus detection rate reported by Khetsuriani et al 1 because many studies in wheezing children have shown virus detection rates of close to 90%. 1 Interestingly, 2 or more viruses were detected in 43% of the children compared with 7% in the study by Khetsuriani et al. Our findings suggest that nearly all exacerbations of asthma in children necessitating hospitalization are associated with viral infection.
