A Flinders University review of 22 studies finds that flushing a toilet can eject aerosols containing microbes into the surrounding air, sometimes reaching breathing height. Risk varies with toilet type, conditions, microbial load, and flush volume; some mitigations include closing the lid when possible, improved ventilation, and design changes to reduce aerosol generation—especially in high-risk settings like hospitals.
A review of 22 studies finds toilet flushing can eject microbes as aerosols into the air for at least 20 seconds, and closing the lid does not fully prevent exposure, though it may reduce it. Turbulent flushes generate more particles, and higher microbial loads increase bioaerosol release, with potential pathogens including Legionella, influenza and norovirus. Ventilation effects remain unclear, but the findings underscore implications for building design and infection control—especially in hospitals and care settings—advocating lower-volume flushes and lid use as precautionary measures rather than guarantees of safety.
