pes. The most common diagnosis among all PIV subtypes was pneumonia. Lower respiratory tract in- fections constituted the majority (76.3%) of PIV infections. The most common diagnosis of PIV type I and II was croup and that of PIV type III was pneumonia. A difference in seasonal variation be- tween subtypes was observed. PIV I (62.2%) was mainly isolated from July to September while PIV type III (86.8%) was isolated from April to July. Conclusion: Lower respiratory infection was most commonly found in hospitalized patients with PIV infection. Clinical features of PIV infection were sim- ilar those seen in Western PIV reports, with the ex- ception of the seasonal outbreak pattern. (Korean J Clin Microbiol 2012;15:54-59)
