Toilet flushes release pathogen-laden aerosols that linger in breathing zone

In the ordinary act of flushing a toilet, science is revealing a hidden choreography of risk that most people have never considered. Researchers reviewing decades of studies have found that the turbulence of a flush lifts pathogen-carrying aerosols to the height where people breathe, where they linger for at least twenty seconds — and that closing the lid, long assumed to be a sufficient safeguard, offers only partial protection. The findings carry particular weight for hospitals and aged care facilities, where immunocompromised individuals face the gravest consequences from pathogens that tra
