How to stop the spread of STDs
Friday, February 23rd, 2007Professor James Moody of Ohio State University recently completed a fascinating study, mapping the romantic and sexual relationships of students at a high school over the course of 18 months. Although there were not many students who had many partners,
The romantic and sexual network at the school created long chains of connections that spread out through the community, with few places where students directly shared the same partners with each other. But they were indirectly linked, partner to partner to partner. One component of the network linked 288 students – more than half of those who were romantically active at the school – in one long chain. (See figure for a representation of the network.)
Granted, to be in the chain, sexual intercourse is not required. Nevertheless, this has profound implications in regard to the spread of STDs. Because students often think that they are acting non-promiscuously by only having one or two partners over eighteen months, they underestimate their potential risk for getting STDs. Because if those one or two partners happened to be linked in a long chain of people, and one of those people happens to have an STD, there is a real chance that a “non-promiscuous” student could end up with an STD.
