Toilet flushing can create infectious aerosols even when lid is closed
One way of covid transmission is toilet flushing releasing aerosols in the air, and a second way of transmission is fecal aerosol transmission in swage pipes.
from the article
In 2003, during the peak of Hong Kong’s SARS outbreak, 321 cases rapidly appeared in a single housing estate. Comprehensive investigations of the outbreak ultimately homed in on the primary case, a man visiting one of the apartment blocks.
On the day the man was visiting he had diarrhea and used a toilet in one of the apartments. Tracking subsequent cases, the investigation discovered the most likely route of viral transmission to other residents was via aerosolized particles discharged into sewage pipes.
Early in 2020, as the COVID-19 pandemic spread around the world, case studies resembling the earlier Hong Kong SARS cluster began to appear. One early cluster in a Chinese apartment building, for example, was widely analyzed and a recently published study concluded fecal aerosol transmission was possibly the cause.
