Restrooms commonly contain bacteria, including E. coli, salmonella, MRSA, HIV, hepatitis B, hepatitis C, and staphylococcus aureus.

Even with adequate ventilation systems and frequent cleaning, it’s impossible to keep public restrooms clean because flushing generates aerosolized droplets. In addition, aerosolized droplets are central in transmitting various infectious diseases, including COVID.
