You Can Catch An Infection From A Public Toilet
Many of us refrain from using public restrooms out of concern for contracting unknown diseases like STDs. Given that we are hardwired to avoid environments that may harbor dangerous infections, which public restrooms most surely do, it makes evolutionary and hygienic sense.
Even though it's true that some public restrooms shouldn't be used by anyone, there is very little risk of disease transmission from even the worst of them, according to science. The majority of infections we are aware of can't endure on the majority of surfaces long enough to infect the following individual. In the unlikely event that they did live, the only ways they may spread infection are through an open wound or sore, the urethral or vaginal system, or both.
