These "newly identified viruses" (NIVs) including human metapneumovirus (HMPV; described pre-SARS), the human rhinovirus (HRV) species C (HRV-Cs), human coronaviruses (HCoVs)-NL63 and -HKU1, human bocavirus (HBoV), and the KI and WU polyomaviruses (KIPyV and WUPyV) are now the focus of intense research, and their involvement in asthma exacerbations is slowly beginning to be determined. 34 In a retrospective study of clinical samples taken over a 20-year period from young children (median age 14.5 months), the percentage of lower respiratory tract illness (LRTI; including asthma exacerbations and bronchiolitis) associated with any HCoV, HCoV-NL63, or HCoV-OC43 was estimated to be 4.6%, 2.6%, and 1.9%, respectively.	./cache/cord-252012-hdjbxah8.txt	./txt/cord-252012-hdjbxah8.txt
