The interhuman transmission is the result of droplets’ projection toward another host or via human contact (e.g., handshaking) or through an inert surface [25]: the estimated half-life of SARS-CoV-2 in the droplets has been estimated to range between 1.1 to 1.2 h and it should be minded that the use of a common N95 mask does not get the risk of contagion down to zero [4, 13].
