Recent prospective studies, which utilized more sensitive methods for detecting respiratory viruses such as multiplex polymerase chain reaction (PCR), have similarly demonstrated that the highest rates of viral respiratory infection occur among children and the frequency of infection tends to decrease with age due to increasing acquired immunity [8] . On the other hand, the percentage of influenza viruses (not including pH1N1) detected in our study during a similar period of time, but in different years accounted for the significant differences found in both studies: a) the collection, preservation and further processing of respiratory samples, and b) the type of cells and IFA reagents used for virus isolation and identification. In contrast, a prospective study of ILI among Brazilian adults, which utilized viral isolation and RT-PCR testing on respiratory samples, detected rhinoviruses in 19.6% of patients [14] .	./cache/cord-289017-vwye3pk9.txt	./txt/cord-289017-vwye3pk9.txt
