We assessed the viability of aerosolized human betacoronavirus OC43 (HCoV-OC43; ATCC VR-1558), rhinovirus-14 (RV-14; VR-284) and feline calicivirus (FCV; VR-782) as representative enveloped non-enveloped respiratory viruses mammals in indoor air under ambient conditions (relative humidity 50±10% temperature 22±2°C) using a room-sized (25 m3; 900 ft3) aerobiology chamber. All virus suspensions contained soil load to simulate presence body fluids they were separately into chamber six-jet Collison nebulizer.
