Internet and STD “Clients who reported seeking sex on the Internet were more likely to have concomitant risk factors for STD/HIV than clients who did not seek sex on the Internet.Thus, seeking sex on the Internet may be a potential risk factor for STD/HIV” McFarlane et al. JAMA 2000;284
“Common Knowledge” • “Multiple studies have identified Internet use to find sex partners as a risk factor of acquisition of sexually transmitted diseases, particularly among MSM” Recent manuscript submitted for journal review
