The results of this study suggest the presence of common respiratory viruses in the lower respiratory tract without determining symptomatic infection even in carefully collected lower samples. This may have important implications on the interpretation of the results on the diagnostic setting.

The accomplishment of a longitudinal study would allow to elucidate the length of stay of these viruses in the respiratory tract, and the existence or not of a permanent viral community in this environment.
