“…transactional partnerships or drug‐sharing contacts) and community norms across populations may further influence the acceptability and delivery of PNS. Formative evidence indicates that PNS may be acceptable to some members of key populations in LMIC , but may be challenging in others . Encouragingly, PNS approaches have also been successfully provided to gay, bisexual, and other men who have sex with men (MSM) and people who inject drugs (PWID) in several high‐income countries for many years and lessons learned from these programmes may inform scale‐up in LMICs.…”

Background. Assisted partner notification services (APNS) may increase HIV testing, early diagnosis, and treatment, but they are not formally implemented in Mexico, where the HIV epidemic is concentrated in men who have sex with men (MSM) and transwomen (TW). We conducted semi-structured interviews to explore partner notification with MSM, TW and health care providers to identify the essential elements to include in the design and implementation of APNS directed to MSM and TW in Mexico City. Afterwards, brainstorm sessions were carried out to produce strategies for implementing APNS. Results. Most participants reported experiences with informal partner notification, but not with APNS. Only one health care provider indicated assisting notification systematically. The main barriers for notifying mentioned by both MSM and TW included fear of (violent) reactions, discrimination and lacking contact information of casual partners. Participants thought it was easier notifying a formal partner, conditional of being well informed about HIV. Given current stigma and lack of awareness, it was suggested that APNS should be preceded by HIV awareness efforts, and be provided by counsellors or peers to mitigate potential rejection or violent reactions. Conclusions. While APNS are not formally implemented in Mexico, all participants supported the service, indicating that APNS can enhance early HIV diagnosis in Mexico. Strategies to implement such services need to be flexible addressing the individual needs of participants, guaranteeing the safety of more vulnerable participants.

“…Data come from Proyecto Enlaces (Links Project), which was designed to compare the effectiveness of partner contact tracing (PCT) (changed to respondent-driven sampling [RDS] after 9 months) and venue-based sampling (VBS) for identifying undiagnosed infection among MSM and TW in Tijuana (as described elsewhere) 14 . PCT (eliciting and contacting sexual partners of participants who were recently diagnosed with HIV) was used between March and December of 2015 15 . RDS, a chain-referral sampling technique that modifies snowball sampling by limiting the number of individuals a participant can recruit, was used between January 2016 and November 2018.…”

OBJECTIVE: To characterize recent HIV infections among newly diagnosed men who have sex with men and transgender women in Tijuana. METHODS: Limiting Antigen (LAg)-Avidity testing was performed to detect recent HIV infection within a cohort of newly-diagnosed men who have sex with men and transgender women in Tijuana. Logistic regression was used to determine characteristics associated with recent infection. A partial transmission network was inferred using HIV-1 pol sequences. Tamura-Nei 93 genetic distances were measured between all pairs of sequences, and the network was constructed by inferring putative transmission links (genetic distances ≤ 1.5%). We assessed whether recent infection was associated with clustering within the inferred network. RESULTS: Recent infection was detected in 11% (22/194) of newly-diagnosed participants. Out of the participants with sequence data, 60% (9/15) with recent infection clustered compared with 31% (43/139) with chronic infection. Two recent infections belonged to the same cluster. In adjusted analyses, recent infection was associated with years of residence in Tijuana (OR = 1.5; 95%CI 1.01–1.09), cocaine use (past month) (OR = 8.50; 95%CI 1.99–28.17), and ever experiencing sexual abuse (OR = 2.85; 95%CI 1.03–7.85). DISCUSSION: A total of 11% of men newly diagnosed with HIV who have sex with men and transgender women in Tijuana were recently infected. The general lack of clustering between participants with recent infection suggests continued onward HIV transmission rather than an outbreak within a particular cluster. DESCRIPTORS: HIV Infections, epidemiology. Sexual and Gender Minorities. Transgender Persons. Disease Transmission, Infectious.
