This is an enveloped virus. The concentration of salt used will provide a reasonable inactivation but not likely to be complete. But this virus is both spread by contact and inhalation of air-borne droplets; it is not water-borne. As such the water is not the medium of transmission. All float centers should focus on disinfection of hard surfaces including chairs, door knobs, check in counters, and all solid surfaces where someone might place their hand. We should be emphasizing this, rather than testing survival times in the float solution.
