The World Health Organization identified men as an essential group to target with HIV testing and treatment strategies;: men who have sex with men (MSM) and male clients of female sex workers (CFSW) account for 35% of new HIV infections globally. Using a cross-sectional design from a community-based HIV prevention project in Tanzania (October 2015-September 2018) and multivariable logistic regression, we identified predictors of HIV seropositivity among men. Of 1,041,343 men on their initial visit to the project, 36,905 (3.5%) were MSM; 567,005 (54.5%) were CFSW; and 437,343 (42.0%) were other men living near hotspots (OMHA). Three predictors of HIV seropositivity emerged across all three groups: being uncircumcised, having sexually transmitted infection symptoms, and harmful drinking of alcohol before sex. Any reported form of gender-based violence among MSM and OMHA and inconsistent condom use among CFSW were associated with HIV seropositivity. These findings may inform community HIV strategies like self-testing, delivery of pre-exposure prophylaxis and antiretroviral therapy, and behavioral change communication targeting men at higher risk of infection.

To meet UNAIDS' 90-90-90 treatment goals, effective approaches to HIV testing services (HTSs) are urgently needed. In 2015, a cross-sectional study was conducted to evaluate effectiveness and feasibility of partner notification for HTS in Tanzania. Men and women newly diagnosed with HIV were enrolled as index clients, listed sexual partners, and given options to notify and link their partners to HTS. Of 653 newly diagnosed individuals, 390 index clients were enrolled, listed 438 sexual partners, of whom 249 (56.8%) were successfully referred. Of 249 partners reaching the facilities, 96% tested for HIV, 148 (61.9%) tested HIV+ (all newly diagnosed), and 104 (70.3%) of partners testing positive were enrolled into HIV care and treatment. Results showed good acceptability, feasibility and effectiveness, as evidenced by high uptake of partner notification among newly diagnosed individuals, over half of listed partners successfully referred, and a very high positivity rate among referred sexual partners.

A growing evidence base supports expansion of partner notification in HIV testing services (HTS) in sub-Saharan Africa. In 2015, a cross-sectional study was conducted in Njombe region, Tanzania, to evaluate partner notification within facility-based HTS. Men and women newly diagnosed with HIV were enrolled as index clients and asked to list current or past sexual partners for referral to HTS. Successful partner referral was 2.5 times more likely among married compared to unmarried index clients and 2.2 times more likely among male compared to female index clients. In qualitative analysis, male as well as female index clients mentioned difficulties notifying past or casual partners, and noted disease symptoms as a motivating factor for HIV testing. Female index clients mentioned gender-specific challenges to successful referral. Women may need additional support to overcome challenges in the partner notification process. In addition to reducing barriers to partner notification specific to women, a programmatic emphasis on social strengths of males in successfully referring partners should be considered.

Scaling up voluntary medical male circumcision (VMMC) to 80% of men aged 15-49 within five years could avert 3.4 million new HIV infections in Eastern and Southern Africa by 2025. Since 2009, Tanzania and Zimbabwe have rapidly expanded VMMC services through different delivery (fixed, outreach or mobile) and intensity (routine services, campaign) models. This review describes the modality and intensity of VMMC services and its influence on the number and age of clients.
