SARS-CoV-2 RNA was not detected in 219 nasal/oro-pharyngeal swabs, analyzed for respiratory disease diagnosis at the National Institute for Infectious Diseases “Lazzaro Spallanzani”, from November 2019 to January 2020; these results suggest lack of unrecognized SARS-CoV-2 circulation before the identification of the first two cases in Italy.
