> Aerosolization of viruses via toilet flushing may be more impactful, compared with aerosolization of bacteria, given differences in response to humidity and in droplet size. Various studies have indicated that viruses retain viability at both low or high relative humidities and, therefore can remain infectious in droplet nuclei and other aerosols, which may stay suspended in the air for hours to days. Also, viruses are likely to aerosolize more easily than bacteria and 94% of virus has been shown to partition into liquid phase rather than solid phase.
