NPAs from a series of 253 infants aged less than 1 year and admitted to the hospital in the period November 2005-May 2006 with a diagnosis of ARTI were examined for hRSV as well as other respiratory viruses by DFA, CC, and qualitative RT-PCR, as reported (Rovida et al., 2005) . In addition, 14 infants with multiple simultaneous (coinfections) or sequential (within 30 days) infections in the respiratory tract (including hRSV) were examined prospectively in order to identify the virus responsible for the current ARTI episode. ./cache/cord-296847-r752bcsu.txt ./txt/cord-296847-r752bcsu.txt
