There's a certain comfort in the toilet seat cover,
the tissue-thin layer of grace between your bare behind and a piece of
cold, dirty plastic. But what happens if you forgo the cover, boldly
plopping down on a surface crawling with who knows what?
Probably nothing, according to public health experts. Seat
covers do not stop germs, they said, and you're not likely to catch an
infection from a toilet, anyway.
Toilet seat covers are absorbent and bacteria and
viruses are tiny, able to pass through the relatively large holes in the
cover's paper, said Kelly Reynolds, a public health researcher at the
University of Arizona. That means they don't stop the spread of germs, she
said, but the risk of germ transmission from your skin touching a toilet seat is
unlikely in the first place.
Germs will more likely spread after you flush, when bits of
fecal matter blast into the air in aerosol form, a phenomenon known as
"toilet plume." From there, Reynolds said, the "bits of fecal
matter settle on surfaces, contaminate hands and then get spread to the eyes,
nose or mouth."
Dr. William Schaffner, a professor of preventative medicine
at Vanderbilt University, agreed. He pooh-poohed seat covers to
the Huffington Post, which found research has refuted notions
that toilet seats spread sexually transmitted infections
or gastrointestinal infections.
“That’s because toilet seats are not a vehicle for the
transmission of any infectious agents—you won’t catch anything,” Schaffner
said.
And covering the seat with toilet paper? That may even make
things worse. Placing pieces of toilet paper around the seat as an impromptu
cover only increases the surface area for germs to multiply on, as Raymond
Martin, a director with the British Toilet Association, told
Buzzfeed. That makes it "considerably less hygienic," he said.
(And toilet plumes may have blasted fecal matter onto the toilet paper anyway.)
The seat covers can keep things cleaner, however, said
Reynolds: They make people more likely to sit on toilets rather than hover over
them, reducing general splatter. That makes them a "net
benefit," she said.
The biggest risk in public restrooms remains the spread of
fecal matter to the mouth, Reynolds said, and that starts with the hands.
Just remember to wash your hands, lathering with soap and scrubbing for 20
seconds before rinsing, as the CDC
recommends. Then you're truly covered.
