Flushing the Toilet May Fling Coronavirus Aerosols All Over


This is nothing new. These facts already were known at the beginning of the pandemic. Here is an article from the New York Times, dated 16th., June, 2020:

Flushing the Toilet May Fling Coronavirus Aerosols All Over

A new study shows how turbulence from a toilet bowl can create a large plume that is potentially infectious to a bathroom's next visitor.

Here's one more behavior to be hyper-aware of in order to prevent coronavirus transmission: what you do after you use the toilet.

Scientists have found that in addition to clearing out whatever business you've left behind, flushing a toilet can generate a cloud of aerosol droplets that rises nearly three feet. Those droplets may linger in the air long enough to be inhaled by a shared toilet's next user, or land on surfaces in the bathroom.

This toilet plume isn't just gross. In simulations, it can carry infectious coronavirus particles that are already present in the surrounding air or recently shed in a person's stool. The research, published Tuesday in the journal Physics of Fluids, adds to growing evidence that the coronavirus can be passed not only through respiratory droplets, but through virus-laden feces, too.

And while it remains unknown whether public or shared toilets are a common point of transmission of the virus, the research highlights the need during a pandemic to rethink some of the common spaces people share.

"The aerosols generated by toilets are something that we've kind of known about for a while, but many people have taken for granted," said Joshua L. Santarpia, a professor of pathology and microbiology at the University of Nebraska Medical Center who was not involved in the research. "This study adds a lot of the evidence that everyone needs in order to take better action."

Typically, the coronavirus is most at home in cells in the lungs and upper respiratory tract. But studies have found it can also dock to cell receptors in the small intestine. Patients have been reported to experience diarrhea, nausea and vomiting among other symptoms.
