This PATH-lead and USAID-funded project hired and trained Online Change Agents (OCAs) in Viet-Nam. It started as a Facebook page in 2015 to allow MSM and TGW to connect and exchange information on HIV prevention and care. Interest was strong and numbers grew exponentially. The OCA model launched in March 2016 and has already had much success (of 236 clients, 91.5% have been referred to HIV testing services; 14.4% of those tested were found to be HIV positive and were supported by their OCA to enrol in ARV treatment).
