Positive rates of multiple respiratoty viruses in the winter/spring of 2006−2009 and whole year of 2009−2010.

<p>Respiratory viruses in each sample collected from week 40 of one year to week 18 of the next year in 2006−2009 and week 19 of 2009 to week 18 of 2010 were detected using multiplex nested RT-PCR, one-step RT-PCR, and PCR assays as described in <i><a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0045807#s2" target="_blank">Materials and Methods</a></i>. Weekly curves of positive rate of common respiratory viruses, including A/H1N1 2009pdm, H3N2, H1N1, influenza B, C, HRV, HPIV, EV, HCoV RSV, AdV, and HMPV viruses in winter/spring 2006−2009 and annual 2009−2010 are shown.
