MSM Testing Initiative (MTI) was a CDC-funded initiative aimed at identifying 3,000 previously undiagnosed HIV-positive men who have sex with men (MSM) and linking 85% of them to care. This initiative was collaboration between Emory University and Abt Associates and employed four outreach and recruitment strategies aimed at reaching undiagnosed MSM. MTI partnered with local Community Based Organizations (CBOs) across the country to implement HIV testing through expanded and enhanced venue-based testing, at-home internet testing, couples voluntary counseling and testing, and episodic testing in high prevalence cities.
