Using Social Media to Increase HIV Testing Among Gay and Bisexual Men, Other Men Who Have Sex With Men, and Transgender Persons: Outcomes From a Randomized Community Trial

We tested an intervention designed to increase human immunodeficiency virus (HIV) testing among men who have sex with men and transgender persons within existing and commonly used social media. At follow-up, intervention communities had significantly higher past 12-month HIV testing than the comparison communities. Findings suggest that promoting HIV testing via social media can increase testing.
