Human bocavirus DNA was frequently detected in serum specimens obtained from patients with acute wheezing, suggesting systemic infection. Results suggest a model for bocavirus infection in which high viral loads are potentially associated with respiratory symptoms and low viral loads indicate asymptomatic shedding. Of the 293 children who were randomized, 259 children (median age, 1.6 years; range, 3 months to 15 years) who had sufficient sample material available for complete virus diagnostic evaluation (nasopharyngeal aspirate specimens were used for PCR [for 16 viruses], virus culture [for 9 viruses], and antigen detection [for 7 viruses]; acute-and convalescent-phase serum samples were used for serologic testing [for 7 viruses]) were included in the present study.	./cache/cord-260457-m1jbpo5l.txt	./txt/cord-260457-m1jbpo5l.txt
