Imagine being able to download a Facebook app that would alert you to your sexually transmitted infection risk based on your friend’s status updates. This may sound far-fetched, and it still is, but as some researchers shift their focus to risk among friend groups, as opposed to just sexual partners, social networks are rapidly becoming a tool to prevent the spread of STIs.
Peter Leone, a professor of medicine at the University of North Carolina’s Center for Infectious Diseases, is one of those experts. Earlier this month, he spoke at an international health conference and underscored the importance of exploring such possibilities. Real-world social networks — in other words, a person’s circle of friends and sexual partners — have already proved to be strong predictors of STI risk, he says. It follows that sites like Facebook, which convene all of those real-world connections in one virtual setting, have huge potential in this arena.
Leone found that when sexual partners of patients newly diagnosed with HIV came in for testing, 20 percent turned up HIV-positive. It might seem counter-intuitive to extend the targeted test circle to those a newly diagnosed patient is merely friends with, but people in the same social circle often sleep with the same people, and might engage in similar risk-related behavior. Instead of looking at people within a particular at-risk demographic, this approach allows them to target known clusters of infection.
Makes you think of the people on your “Close Friends” list a bit differently, doesn’t it?
