Influenza (and the Common Cold)
Influenza and other viruses can live for as many as two or three days on nonporous surfaces, including your phone, the remote control and (no surprise) the toilet seat -- and some of these viral strains may live even longer. Bird flu, for example, can live for weeks, just waiting for you to have a seat [source: Wood, et al]. The common cold, on the other hand (or would that be the other cheek?), isn't that much of a threat. You could still catch a cold from the toilet seat, but rhinovirus usually survives less than a day on hard surfaces [source: Winther].
The trick with the cold and flu is not to touch your eyes, nose or mouth after you've touched the toilet seat (or a doorknob, or your office keyboard, etc.). It's easily transmitted through mucous membranes. We shouldn't have to remind you, but always wash your hands after using the bathroom.
Author's Note: 5 Diseases You Really Can Get From a Toilet
It's undeniably gross when you discover the person who visited the public bathroom before you had, ahem, bad aim, but the seat isn't the filthiest thing about a toilet. Actually, that's probably the flusher. Think about it; how often do you flush with your foot instead of your hand? Right.
