HIV self\u2010testing (HIVST) services were promoted through TikTok influencers to target AYAs vulnerable to HIV. An automated chatbot provided real\u2010time responses to client inquiries, and trained counsellors provided confidential, text\u2010based counselling daily. Clients who completed risk assessments received personalized recommendations for HIVST based on their risk profile. Clients who submitted their HIVST results received post\u2010test counselling and linkage to care and prophylactic treatment. Multivariable logistic regression was used to assess risk factors for reactive HIVST kit results. The per unit direct cost of the programme's performance metrics were assessed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 8863 clients provided 11,536 risk assessments. The majority were male (76.3%), under the age of 30 (76.0%), identified as members of key populations (60.4%) and first\u2010time testers (56.1%). Additionally, 27.8% had a history of sexually transmitted infections (3,202\/11,536), 16.5% reported receiving money or incentives for sex (1908\/11,536) and clients indicated an average of 2.6 sexual partners in the past month (SD 3.4).
