"The Lid Debate: Does Flushing with the Toilet Lid Down Really Prevent Viral Contamination?"

Flushing the toilet releases a plume of aerosolized bacteria and viruses into the air, regardless of whether the lid is up or down. Research shows that the most contaminated areas in the bathroom after flushing include the toilet bowl water, toilet brush, toilet seat, floor surrounding the toilet, and bathroom walls. Regular disinfection of all restroom surfaces, especially after toilet brushing, and the use of a disinfectant with residual microbicidal activity are recommended to minimize the risk of infection, particularly for individuals with compromised immune systems.
