Here’s a fun number to keep in mind as we head into the weekend: more than 110M people have an STD.

According to two studies in the “Sexually Transmitted Diseases” journal, twenty million more people in the US get an STD each year, with half of these people ages 15-24. (The article doesn’t mention the overall age range of the study.)

Assuming the US population is the same as it was for the 2010 Census, that would mean 35%+ of the population has an STD.

Just something to keep in mind. Happy Friday!
