It is not known how long omicron survives on surfaces, and other coronaviruses have been tested that can survive on inanimate surfaces for up to 6 to 9 days if not sterilized. One study evaluated the survival time of viruses dried on plastic surfaces at room temperature and found that a sample containing a new coronavirus was detectable as infectious at 6 days but not at 9 days. A systematic evaluation of similar studies found that a variety of disinfectants, including ethanol at concentrations of 62%-71%, inactivated a number of coronaviruses related to neocoronaviruses within 1 minute. Under experimental conditions, simulated daylight inactivated neocoronaviruses within 15-20 minutes, and the higher the ultraviolet-B band (UVB) level, the faster the inactivation. Data on other coronaviruses suggest that virus retention time on surfaces may also be affected by ambient temperature, relative humidity and initial virus load.
