• Complete inactivation of coronaviruses on surfaces and in aerosols required at least 15 minutes within a maximum distance from the UV emitter up to 1 meter, according to a systematic review of 18 studies reporting on the efficacy of UV technologies against coronaviruses (n=6 against SARS-CoV-2). The authors noted significant heterogeneity among the studies in studied variables, such as viral medium and UV intensity used.
