RESUMEN

To better understand male and female sexual partnerships among men who have sex with men (MSM), we used data from a 2019 biobehavioral survey among MSM in Harare and Bulawayo, Zimbabwe to conduct bivariate analyses and multivariable logistic regression to determine whether sociodemographic characteristics and HIV-related factors were associated with having both male and female sexual partnerships within the last 6 months. Of included MSM (N = 1143), 31% reported both male and female partnerships in the last 6 months. Being married/cohabiting (adjusted odds ratio (aOR) = 8.58, 95% confidence interval (CI) = 4.92-14.95) or separated/divorced/widowed (aOR = 1.96, 95% CI = 1.24-3.08) vs. being single, and hazardous alcohol consumption (aOR = 1.58, 95% CI 1.19-2.09) were associated with higher odds of having both male and female recent partnerships. Being aged 35 + vs. 18-24 (aOR = 0.50, 95% CI = 0.31-0.81), condomless receptive anal intercourse at last sex with the main male partner (aOR = 0.43, 95% CI = 0.26-0.74), and positive HIV status (aOR = 0.46, 95% CI = 0.31-0.67) were associated with lower odds of recent male and female partnerships. MSM in Harare who reported harassment/abuse (aOR = 3.16, 95% CI = 1.72-5.79) had higher odds of both male and female partnerships than MSM in Bulawayo reporting harassment/abuse. The prevalence of both male and female recent partnerships (31%) was lower among MSM in this survey than in other biobehavioral surveys of MSM in sub-Saharan Africa. Findings suggest that MSM with recent male and female partnerships compared to MSM with only male recent partners have lower odds of positive HIV status and participate in behaviors that lower HIV risk; however, the direction of these relationships cannot be determined due to the cross-sectional nature of the data. The findings also suggest a possible connection between experiences of stigma of MSM behavior and not having both male and female partnerships that warrants further exploration. Accessible, stigma-free HIV testing and education programming that considers the potential overlap between the MSM and general populations via both male and female partnerships and the associated behaviors could be a key component of HIV elimination in Zimbabwe.

RESUMEN

BACKGROUND: Syphilis increases human immunodeficiency virus (HIV) acquisition risk and impacts the immunologic and virologic response among people living with HIV (PLHIV). We assessed the prevalence of active or current syphilis and HIV/syphilis and their correlates among men who have sex with men (MSM), transwomen, and genderqueer (TGW/GQ) individuals in Zimbabwe. METHODS: Among a respondent-driven sample of MSM and TGW/GQ who were tested for HIV and syphilis in Harare and Bulawayo, Zimbabwe in 2019 (n = 1511), multiple logistic regression was used to assess correlates of active syphilis. Unadjusted logistic regression was used among PLHIV (n = 340) due to small sample size. All analyses were unweighted as data did not reach convergence for HIV. RESULTS: Prevalence of active syphilis overall and among PLHIV was 5.5% and 10.1%, respectively, in Harare, and 5.6% and 11.0%, respectively, in Bulawayo. Participants were more likely to have active syphilis if they were PLHIV (adjusted odds ratio [aOR], 2.2; 95% confidence interval [CI], 1.4-3.6), aged 25-34 years (aOR, 2.2 years; 95% CI, 1.3-3.8 years; reference, 18-24 years), or self-report sexually transmitted infection symptoms (aOR, 1.8; 95% CI, 1.1-3.0). Compared with Bulawayo TGW/GQ, MSM in Harare (aOR, 0.2; 95% CI, 0.1-0.5) and Bulawayo (aOR, 0.2; 95% CI, 0.1-0.4), and TGW/GQ in Harare (aOR, 0.2; 95% CI, 0.1-0.6) were less likely to have active syphilis. Among PLHIV, coinfection was 13.0% among TGW/GQ and 9.7% among MSM. Odds of coinfection were higher for those aged 25 to 34 years (OR, 3.7 years; 95% CI, 1.2-11.1 years) and lower among Harare MSM (OR, 0.2; 95% CI, 0.1-0.7), Bulawayo MSM (OR, 0.1; 95% CI, 0.0-0.4), and Harare TGW/GQ (OR, 0.1; 95% CI, 0.0-0.4) compared with Bulawayo TGW/GQ. CONCLUSIONS: Findings highlight a high burden of syphilis among MSM and TGW/GQ and underscore the importance of HIV/syphilis detection and improved service delivery for these groups.

RESUMEN

Though stigma is a recognized contributor to the disproportionate HIV burden among sexual and gender minorities (SGM) in sub-Saharan Africa, data describing this association among Zimbabwean SGM are limited. We examined relationships between SGM stigma and HIV and the potential for social cohesion to moderate the association among Zimbabwean men who have sex with men, transgender women, and genderqueer individuals. Consenting participants (n = 1511) recruited through respondent-driven sampling for a biobehavioral survey in Harare and Bulawayo completed structured interviews and received HIV testing. Reported SGM stigma was common (68.9% in Harare and 65.3% in Bulawayo) and associated with HIV infection in Harare (adjusted prevalence ratio [aPR] = 1.82, 95% confidence interval [CI] = 1.27-2.62) and Bulawayo (aPR = 1.51, 95% CI = 1.15-2.00) in relative risk regression. Social cohesion did not moderate these relationships. Findings demonstrate stigma's association with HIV vulnerability among Zimbabwean SGM, highlighting the need for stigma-mitigation to reduce HIV transmission in this population.

RESUMEN

BACKGROUND: In South Africa, 60% of female sex workers (FSW) are living with HIV, many of whom experience structural and individual barriers to antiretroviral therapy (ART) initiation and adherence. Community-based decentralized treatment provision (DTP) may mitigate these barriers. To characterize optimal implementation strategies, we explored preferences for DTP among FSW living with HIV in Durban, South Africa. METHODS: Thirty-nine semi-structured in-depth interviews were conducted with FSW living with HIV (n = 24), and key informants (n = 15) including HIV program implementers, security personnel, and brothel managers. Participants were recruited using maximum variation and snowball sampling. Interviews were conducted in English or isiZulu between September-November 2017 and analyzed using grounded theory in Atlas.ti 8. RESULTS: DTP was described as an intervention that could address barriers to ART adherence and retention, minimizing transport costs, time and wage loss from clinic visits, and act as a safety net to address FSW mobility and clinic access challenges. Respondents highlighted contextual considerations for DTP and suggested that DTP should be venue-based, scheduled during less busy times and days, and integrate comprehensive health services including psychological, reproductive, and non-communicable disease services. ART packaging and storage were important for community-based delivery, and participants suggested DTP should be implemented by sex work sensitized staff with discrete uniform and vehicle branding. CONCLUSIONS: Incorporating FSW preferences may support implementation optimization and requires balancing of tensions between preferences and feasibility. These data suggest the potential utility of DTP for FSW as a strategy to address those most marginalized from current ART programs in South Africa.

RESUMEN

BACKGROUND: Intermittent preventive treatment of malaria in infants (IPTi) with sulfadoxine-pyrimethamine (SP) is a proven strategy to protect infants against malaria. Sierra Leone is the first country to implement IPTi nationwide. IPTi implementation was evaluated in Kambia, one of two initial pilot districts, to assess quality and coverage of IPTi services. METHODS: This mixed-methods evaluation had two phases, conducted 3 (phase 1) and 15-17 months (phase 2) after IPTi implementation. Methods included: assessments of 18 health facilities (HF), including register data abstraction (phases 1 and 2); a knowledge, attitudes and practices survey with 20 health workers (HWs) in phase 1; second-generation sequencing of SP resistance markers (pre-IPTi and phase 2); and a cluster-sample household survey among caregivers of children aged 3-15 months (phase 2). IPTi and vaccination coverage from the household survey were calculated from child health cards and maternal recall and weighted for the complex sampling design. Interrupted time series analysis using a Poisson regression model was used to assess changes in malaria cases at HF before and after IPTi implementation. RESULTS: Most HWs (19/20) interviewed had been trained on IPTi; 16/19 reported feeling well prepared to administer it. Nearly all HFs (17/18 in phase 1; 18/18 in phase 2) had SP for IPTi in stock. The proportion of parasite alleles with dhps K540E mutations increased but remained below the 50% WHO-recommended threshold for IPTi (4.1% pre-IPTi [95%CI 2-7%]; 11% post-IPTi [95%CI 8-15%], p < 0.01). From the household survey, 299/459 (67.4%) children ≥ 10 weeks old received the first dose of IPTi (versus 80.4% for second pentavalent vaccine, given simultaneously); 274/444 (62.5%) children ≥ 14 weeks old received the second IPTi dose (versus 65.4% for third pentavalent vaccine); and 83/217 (36.4%) children ≥ 9 months old received the third IPTi dose (versus 52.2% for first measles vaccine dose). HF register data indicated no change in confirmed malaria cases among infants after IPTi implementation. CONCLUSIONS: Kambia district was able to scale up IPTi swiftly and provide necessary health systems support. The gaps between IPTi and childhood vaccine coverage need to be further investigated and addressed to optimize the success of the national IPTi programme.

RESUMEN

BACKGROUND: Many challenges exist in providing equitable access to rural healthcare in the Democratic Republic of the Congo (DRC). WHO recommends student exposure to rural clinical rotations to promote interest in rural healthcare. Challenges to rural engagement include lack of adequate infrastructure and staff to lead rural education. This case report highlights key steps in developing a rural rotation program for DRC nursing students. Case presentation To implement a rural rotation (RR) program, ICAP at Columbia University (ICAP) consulted with students, the Ministries of Health (MoH) and Education (MoE), and nursing schools to pilot and expand a rural rotation program. Nursing schools agreed to place students in rural clinics and communities. Key stakeholders collaborated to assess and select rural sites based on availability of nursing mentors, educational resources, security, accessibility, and patient volume. To support this, 85 preceptors from 55 target schools and 30 rural health facilities were trained of which 30 were selected to be "master trainers". These master trainers led the remaining 55 preceptors implementing the rural rotation program. We worked with rural facilities to engage community leaders and secure accommodation for students. A total of 583 students from five Lubumbashi schools and two rural schools outside Kinshasa participated across 16 rural sites (298 students in 2018-2019 school year and 285 in 2019-2020). Feedback from 274 students and 25 preceptors and nursing school leaders was positive with many students actively seeking rural assignments upon graduation. For example, 97% agreed or strongly agreed that their RR programs had strengthened their educational experience. Key challenges, however, were long-term financial support (35%) for rural rotations, adequate student housing (30%) and advocacy for expanding the rural workforce. CONCLUSIONS: With nearly 600 participants, this project showed that a RR program is feasible and acceptable in resource-limited settings yet availability of ample student accommodation and increasing availability of rural jobs remain health system challenges. Using a multipronged approach to rural health investment as outlined by WHO over two decades ago remains essential. Attracting future nurses to rural health is necessary but not sufficient to achieve equitable health workforce distribution.

RESUMEN

OBJECTIVES: While female sex workers (FSW) are nearly 14 times more likely to be living with HIV than non-FSW, less than 40% of FSW living with HIV are on antiretroviral therapy (ART). We sought to understand how the work environment influences ART access and adherence for FSW in preparation for the Siyaphambili trial. METHODS: FSW living with HIV (n=24) and key informants (n=15) were recruited to participate in semistructured in-depth interviews using maximum variation and snowball sampling, respectively. FSW were recruited on key variants including type of sex work venue, primary work time and history of ART use. Data were collected between September and November 2017 in Durban, South Africa. Interviews were audio-recorded, transcribed and translated. Data were then coded applying grounded theory in Atlas.ti. RESULTS: FSW experienced occupational barriers to adherence including work-related migration, substance use and theft of ART on the job. Fear of wage loss due to HIV disclosure to clients and brothel managers prevented some FSW from accessing ART at their clinic and taking medications while working. FSW employed coping strategies to overcome barriers including sharing ART with colleagues, carrying small supplies of ART and visiting the clinic prior to appointments for ART refills. Further, some FSW received adherence support from colleagues who were also living with HIV. CONCLUSIONS: Considering these occupational pressures on FSW and supporting positive coping strategies are important when designing and implementing HIV treatment programmes. Findings suggest strengthening social cohesion and supporting differentiated care efforts to improve HIV outcomes among FSW living with HIV.

RESUMEN

Nearly 75 percent of female sex workers (FSWs) in Port Elizabeth, South Africa are mothers, many of whom engage in sex work during pregnancy or after delivery. We conducted in-depth interviews with 22 postpartum and 8 pregnant FSWs in Port Elizabeth. Interview guides were used to probe women's experiences, challenges, and concerns about selling sex during pregnancy and post-delivery in a high-HIV-prevalence context. Interviews were transcribed, translated, and coded using thematic analysis. FSWs experienced and feared violence by clients during pregnancy, highlighting the need for safe work environments. Further, FSWs expressed concerns about HIV acquisition and vertical transmission during the perinatal period. Physical challenges related to pregnancy affected women's ability to work. Returning to work post-delivery presented barriers to initiating and practicing exclusive breastfeeding. As a result, many FSWs practiced mixed feeding. Interventions, tailored to respond to FSW's challenges and experiences, may offer improved health outcomes in this context.

RESUMEN

BACKGROUND: Late presentation combined with limited engagement in antenatal care (ANC) increases risk of vertical transmission among mothers living with HIV. Female sex workers (FSW) have more than four times greater burden of HIV than other women of reproductive age in South Africa and the majority of FSW are mothers. For mothers who sell sex and are at increased HIV acquisition risk, timely and routine ANC seeking is especially vital for prevention of vertical transmission. This study represents a mixed-methods study with FSW in Port Elizabeth, South Africa, to characterize factors influencing ANC seeking behaviors in a high HIV prevalence context. METHODS: FSW (n = 410) were recruited into a cross-sectional study through respondent-driven sampling between October 2014 and April 2015 and tested for HIV and pregnancy. A sub-sample of pregnant and postpartum women (n = 30) were invited to participate in in-depth interviews (IDIs) to explore their current or most recent pregnancy experiences. IDIs were coded using a modified grounded theory approach and descriptive analyses assessed the frequency of themes explored in the qualitative analysis among the quantitative sample. RESULTS: In the quantitative survey, 77% of FSW were mothers (313/410); of these, two-thirds were living with HIV (212/313) and 40% reported being on antiretroviral therapy (ART) (84/212). FSW in the qualitative sub-sample reported unintended pregnancies with clients due to inconsistent contraceptive use; many reported discovering their unintended pregnancies between 4 and 7 months of gestation. FSW attributed delayed ANC seeking and ART initiation in the second or third trimesters to late pregnancy detection. Other factors limiting engagement in ANC included substance and alcohol use and discontent with previous healthcare-related experiences. CONCLUSIONS: Late pregnancy discovery, primarily because pregnancies were unplanned, contributed to late ANC presentation and delayed ART initiation, increasing risks of vertical HIV transmission. Given limited ART coverage among participants, addressing the broader sexual and reproductive health and rights needs of mothers who sell sex has important implications for preventing vertical transmission of HIV. Integrating comprehensive family planning services into FSW programming, as well as providing active linkage to ANC services may reduce barriers to accessing timely ANC, decreasing risks of vertical transmission.

RESUMEN

In South Africa, 60% of female sex workers are estimated to be living with human immunodeficiency virus (HIV). Many of these women face structural and individual-level barriers to initiating, accessing, and adhering to antiretroviral therapy (ART). While data are limited, it is estimated that less than 40% of sex workers living with HIV achieve viral suppression, leading to suboptimal clinical outcomes and sustained risks of onward sexual and vertical HIV transmission. Siyaphambili, a NINR/NIH-funded study, focuses on studying optimal implementation strategies for meeting HIV treatment needs among cisgender female sex workers living with HIV who are not virally suppressed. Here, we present the study protocol of this sequential multiple assignment randomized trial. In total, 800 viremic female sex workers will be enrolled into an 18-month adaptive implementation study to 1) compare the effectiveness and durability of a nurse-led decentralized ART treatment program versus an individualized case management approach, in isolation or in combination to achieve viral suppression and 2) estimate incremental cost-effectiveness of interventions and combinations of interventions. The primary outcome is a combined intention-to-treat outcome of retention in ART care and viral suppression at 18 months with secondary implementation outcomes. Siyaphambili aims to inform the implementation of and scale-up of HIV treatment services for female sex workers by determining the minimal package of services needed to achieve viral suppression and by characterizing individuals in need of more intensive HIV treatment approaches.

RESUMEN

Parental obligations influence sexual behaviour among female sex workers (FSW) and may serve as a risk or protective factor for HIV acquisition. How these obligations affect behaviours beyond HIV prevention, including HIV care, is understudied. We analysed 25 interviews conducted with 11 mothers who sell sex and are living with HIV, and 4 key informants as part of a larger study examining the positive health, dignity, and prevention needs of FSW in eSwatini. Despite awareness of HIV reinfection, FSW initiated sex work and engaged in condomless sex due to financial pressures of providing for children. While women attributed having condomless sex to their obligations as a provider, motherhood also served as motivation to engage in HIV care. Further, FSW described children as a source of support in HIV care. Children reminded mothers to take their medications, prepared food to take with medications, and assisted with travel to the clinic.

RESUMEN

INTRODUCTION: We sought to characterize social and structural drivers of HIV vulnerability for transgender women (TGW) in Zimbabwe, where TGW are not legally recognized, and explore differences in vulnerability by feminine presentation. METHODS: A secondary analysis was conducted with a sub-sample of participants recruited from a 2019 respondent-driven sampling survey that comprised men who have sex with men, TGW and genderqueer individuals assigned male sex at birth, from two cities in Zimbabwe. Survey questionnaires captured information related to socio-demographics, sexual and substance use behaviours, and social and structural barriers to HIV services. Secondary analyses were restricted to participants who identified as female, transfemale or transwomen (236/1538) and were unweighted. Descriptive statistics were used to calculate sample estimates and chi-square and Fisher's exact tests were used to assess differences in vulnerability by feminine presentation. RESULTS: Among 236 TGW, almost half (45.3%) presented as feminine in the 6 months preceding the survey and 8.5% had ever used hormones to affirm their gender identities. Median age among TGW was 23 years (interquartile range: 20-26). Feminine presenting TGW in our sample had higher prevalence of arrest (15.9% vs. 3.9%), rejection by family/friends (38.3% vs. 14.0%), employment termination (11.2% vs. 3.9%), employment refusal (14.0% vs. 3.9%), denial of healthcare (16.8% vs. 2.3%), physical, sexual or verbal harassment or abuse (59.8% vs. 34.1%), alcohol dependence (32.7% vs. 12.4%), recent transactional sex with a male or TGW partner (30.8% vs. 13.3%) and recent non-injection drug use (38.3% vs. 20.2%) than non-feminine presenting TGW (all p-value <0.05). CONCLUSIONS: Findings suggest that TGW, particularly feminine presenting TGW, experience social and structural inequities which may contribute to HIV vulnerability. Interventions aimed at addressing inequities, including trans competency training for providers and gender-affirming, psychosocial and legal support services for TGW, might mitigate risk.

RESUMEN

Objectives: To measure HIV and Hepatitis B virus (HBV) prevalence and associated risk behaviors among men who have sex with men (MSM) and transgender women/genderqueer individuals (TGW/GQ) in Zimbabwe. Methods: We conducted a biobehavioral survey using respondent-driven sampling (RDS) among adult MSM and TGW/GQ in Harare and Bulawayo, Zimbabwe in 2019. Participants completed a questionnaire and underwent testing for HIV and HBV. Results: Overall, 1,510 (Harare: 694, Bulawayo 816) participants were enrolled and consented to testing; 3.8 % (58) tested positive for HBV, 22.5 % (339) tested positive for HIV, and 2.2 % (33) tested positive for both HIV and HBV. HBV prevalence was higher among participants with HIV compared to HIV-negative participants (9.7 % vs. 2.1 %, p < 0.0001). Overall, HBV prevalence was not statistically different between MSM and TGW/GQ (3.7 % vs 4.5 %, p = 0.49) nor between Harare and Bulawayo (3.3 % vs 4.3 %, p = 0.33). Conclusions: Our survey demonstrates the prevalence of HBV among MSM and TGW/GQ is lower than other estimates of HBV among MSM in Africa but remains high among our survey population living with HIV highlighting the need to expand HBV testing and treatment services, especially among people with HIV in Zimbabwe.

RESUMEN

BACKGROUND: In 2021, the HIV prevalence among South African adults was 18% and more than 2 million people had uncontrolled HIV and, therefore, had increased risk of poor outcomes with SARS-CoV-2 infection. We investigated trends in COVID-19 admissions and factors associated with in-hospital COVID-19 mortality among people living with HIV and people without HIV. METHODS: In this analysis of national surveillance data, we linked and analysed data collected between March 5, 2020, and May 28, 2022, from the DATCOV South African national COVID-19 hospital surveillance system, the SARS-CoV-2 case line list, and the Electronic Vaccination Data System. All analyses included patients hospitalised with SARS-CoV-2 with known in-hospital outcomes (ie, who were discharged alive or had died) at the time of data extraction. We used descriptive statistics for admissions and mortality trends. Using post-imputation random-effect multivariable logistic regression models, we compared characteristics and the case fatality ratio of people with HIV and people without HIV. Using modified Poisson regression models, we compared factors associated with mortality among all people with COVID-19 admitted to hospital and factors associated with mortality among people with HIV. FINDINGS: Among 397 082 people with COVID-19 admitted to hospital, 301 407 (75·9%) were discharged alive, 89 565 (22·6%) died, and 6110 (1·5%) had no recorded outcome. 270 737 (68·2%) people with COVID-19 had documented HIV status (22 858 with HIV and 247 879 without). Comparing characteristics of people without HIV and people with HIV in each COVID-19 wave, people with HIV had increased odds of mortality in the D614G (adjusted odds ratio 1·19, 95% CI 1·09-1·29), beta (1·08, 1·01-1·16), delta (1·10, 1·03-1·18), omicron BA.1 and BA.2 (1·71, 1·54-1·90), and omicron BA.4 and BA.5 (1·81, 1·41-2·33) waves. Among all COVID-19 admissions, mortality was lower among people with previous SARS-CoV-2 infection (adjusted incident rate ratio 0·32, 95% CI 0·29-0·34) and with partial (0·93, 0·90-0·96), full (0·70, 0·67-0·73), or boosted (0·50, 0·41-0·62) COVID-19 vaccination. Compared with people without HIV who were unvaccinated, people without HIV who were vaccinated had lower risk of mortality (0·68, 0·65-0·71) but people with HIV who were vaccinated did not have any difference in mortality risk (1·08, 0·96-1·23). In-hospital mortality was higher for people with HIV with CD4 counts less than 200 cells per µL, irrespective of viral load and vaccination status. INTERPRETATION: HIV and immunosuppression might be important risk factors for mortality as COVID-19 becomes endemic.

RESUMEN

BACKGROUND: Despite achievements in the HIV response, social and structural barriers impede access to HIV services for key populations (KP) including men who have sex with men (MSM), transgender women (TGW), and people who inject drugs (PWID). This may be worsened by the COVID-19 pandemic or future pandemic threats. We explored the impact of COVID-19 on HIV services and sexual and substance use behaviors among MSM/TGW and PWID in Zambia as part of a formative assessment for two biobehavioral surveys. METHODS: From November-December 2020, 3 focus groups and 15 in-depth interviews (IDIs) with KP were conducted in Lusaka, Livingstone, Ndola, Solwezi, and Kitwe, Zambia. Overall, 45 PWID and 60 MSM/TGW participated in IDIs and 70 PWID and 89 MSM/TGW participated in focus groups. Qualitative data were analyzed using framework matrices according to deductive themes outlined in interview guides. RESULTS: KP reported barriers to HIV testing and HIV treatment due to COVID-19-related disruptions and fear of SARS-CoV-2 exposure at the health facility. MSM/TGW participants reported limited supply of condoms and lubricants at health facilities; limited access to condoms led to increased engagements in condomless sex. Restrictions in movement and closure of meet-up spots due to COVID-19 impeded opportunities to meet sex partners for MSM/TGW and clients for those who sold sex. COVID-19 restrictions led to unemployment and loss of income as well as to shortages and increased price of drugs, needles, and syringes for PWID. Due to COVID-19 economic effects, PWID reported increased needle-sharing and re-use of needles. CONCLUSIONS: Participants experienced barriers accessing HIV services due to COVID-19 and PWID attributed unsafe needle use and sharing to loss of income and lack of affordable needles during pandemic-related restrictions. To maintain gains in the HIV response in this context, strengthening harm reduction strategies and improvements in access to HIV services are necessary.

RESUMEN

Key populations including men who have sex with men (MSM), female sex workers, people who inject drugs, transgender persons, and prisoners account for nearly 50% of new HIV infections globally. To inform the HIV response and monitor trends in HIV prevalence and incidence among key populations, countries have increased efforts to implement biobehavioral surveys (BBS) with these groups as part of routine surveillance. Yet the marginalized nature of populations participating in a BBS requires contextually acceptable and appropriate strategies for effective implementation. We conducted a formative assessment to inform the first BBS conducted with MSM and others assigned male who have sex with men (OAMSM) in Zimbabwe, where same-sex sexual behaviors are illegal and highly stigmatized and describe applications of our findings. Qualitative data were collected through four focus groups with 32 MSM/OAMSM and 25 in-depth interviews (15 MSM/OAMSM, 10 service providers/gatekeepers) from December 2018 to January 2019. Rapid assessment techniques were employed including rapid identification of themes from audio recordings and review of detailed field notes and memos to identify key themes. Findings from this assessment included contextually relevant considerations including behaviors and terminology to avoid when working with MSM/OAMSM in Zimbabwe, appropriate compensation amounts for survey participation, proposed data collection sites, and differences in sexual openness, marital status, and networks among younger and older MSM/OAMSM. Participants also reported strong network ties suggesting respondent-driven sampling-a peer chain referral approach-to be an appropriate recruitment method in this context. Taken together, these findings highlighted key considerations and strategies for implementation to ensure the subsequent BBS in Zimbabwe was both acceptable and appropriate. These results and applications of these results are important for informing surveillance efforts and broader HIV-related engagement efforts among MSM/OAMSM in Zimbabwe as well as in other contextually similar countries in Southern Africa.

RESUMEN

INTRODUCTION: Zimbabwe is scaling up pre-exposure prophylaxis (PrEP) for key populations, including men who have sex with men (MSM) and transgender women (TGW). To assess implementation and inform HIV programming, we evaluated gaps in PrEP awareness, uptake and use, and correlates of awareness and uptake among a sample of MSM, TGW and genderqueer individuals (GQ) in Harare and Bulawayo, Zimbabwe. METHODS: Respondent-driven sampling was used to recruit 1194 MSM and 344 TGW/GQ aged ≥18 to participate in a cross-sectional survey assessing HIV-related outcomes in 2019. Consenting participants completed a questionnaire on socio-demographic information, sexual risk practices and engagement in HIV services and underwent HIV testing. Descriptive statistics were used to assess the PrEP cascade. Multiple logistic regression models were used to identify factors associated with PrEP awareness and uptake among HIV-negative participants. Data were unweighted as the sample did not reach convergence on key estimates. RESULTS: Among the 1167 HIV-negative participants, most (79.2%) were MSM compared to TGW/GQ (20.8%). Median age was 24 years. Overall, 45.8% were aware of PrEP and of those, 31.3% had ever taken PrEP. Most (71.1%) reporting never taking PrEP were willing to start PrEP; the main reasons for never starting PrEP included not knowing where to access it (24.8%) and fearing side effects (20.4%). Among those who had ever taken PrEP, 74.9% had taken PrEP in the last 6 months; of these, 42.4% had taken PrEP the day of or day preceding the survey. Side effects represented the most common (59.5%) reason for discontinuing PrEP. MSM (adjusted odds ratio [aOR]: 2.5, 95% confidence interval [CI]: 1.8-3.6) and TGW/GQ in Harare (aOR: 3.1, 95% CI: 2.1-4.7), and TGW/GQ in Bulawayo (aOR: 2.4, 95% CI: 1.1-5.3) had higher awareness of PrEP than MSM in Bulawayo. Overall, TGW/GQ were more likely to have ever taken PrEP compared to MSM (aOR: 1.6, 95% CI: 1.01-2.4). CONCLUSIONS: Findings emphasize the need for tailored interventions to promote PrEP among key populations. As HIV programs in Zimbabwe continue to expand PrEP services, these data, including barriers to starting and continuing PrEP, can inform strategies to address gaps along the PrEP cascade.

RESUMEN

In Africa, rapid testing for recent HIV infection (RTRI) is being scaled up; however, use of the recent infection testing algorithm (RITA), which uses viral load (VL) to confirm RTRI-recent infections, is not a widespread practice. We present results of recently acquired HIV infections among men who have sex with men (MSM), transgender women, and genderqueer (TGW/GQ) individuals with newly diagnosed HIV infection in Zimbabwe as per the national approach (RTRI) and applying a RITA. In 2019, 1,538 MSM and TGW/GQ in Harare and Bulawayo, Zimbabwe were recruited to participate in a biobehavioral survey using respondent-driven sampling. Consenting participants received HIV testing and all HIV-positive specimens were tested with the RTRI Asanté HIV-1 Rapid Recency Assay, and for VL and CD4 count. RTRI-recent participants with unsuppressed VL (≥1,000 copies/mL) were classified as RITA-recent. Descriptive statistics were used to summarize results among RTRI-recent and RITA-recent participants. Among those tested for HIV (1,511/1,538), 22.5% (340/1,511) tested positive and of those, 55.0% (187/340) self-reported an HIV-negative or unknown status. Among these, 8.6% (16/187) were classified as RTRI-recent and 91.4% (171/187) were classified as RTRI-long term. After accounting for VL, RITA-recency was 1.1% (2/187). Two of 16 (12.5%) RTRI-recent infections were RITA-recent. VL among RITA-recent cases were 9,052 copies/mL and 40,694 copies/mL and both had CD4 counts <500. Data highlight misclassification of recent infections among MSM and TGW/GQ with newly diagnosed HIV infection using RTRI. With the incorporation of VL, >85% of RTRI-recent cases were reclassified as RITA-long term. True characterization of recent infections may not be possible without VL testing, which remains challenging in resource-limited settings.

RESUMEN

BACKGROUND: Globally, men who have sex with men (MSM), transgender women, and genderqueer individuals are at greater risk for HIV than the general population although little data are available from these groups in Zimbabwe, a country with a national adult HIV prevalence of 12·9%. We aimed to examine progress towards the UNAIDS 90-90-90 treatment targets and factors associated with meeting the targets among a sample of MSM, transgender women, and genderqueer individuals in Zimbabwe. METHODS: In this cross-sectional survey in 2019, we used respondent-driven sampling to identify MSM, transgender women, and genderqueer individuals aged at least 18 years to participate in a biobehavioural survey in Harare and Bulawayo, Zimbabwe. Participants were eligible to participate if they were assigned male at birth; had engaged in anal or oral sex with a man in the past 12 months; resided in Harare or Bulawayo for at least 1 month; spoke English, Shona, or Ndebele; provided written informed consent; and were in possession of a valid recruitment coupon if applicable. Enrolled participants completed a questionnaire and underwent HIV testing, and off-site viral load testing was done on all HIV-positive samples. Unweighted bivariate analyses and multivariable logistic regression models were used to evaluate the association of sociodemographic, behavioural, and other factors with HIV-positive status awareness among MSM, transgender women, and genderqueer individuals, and with viral load suppression among MSM. Analyses were done firstly using self-reported information and then by classifying those with a viral load of less than 200 copies per mL as being aware of their status and on treatment (viral load recategorisation). FINDINGS: Among MSM, 248 (21%; 95% CI 19-24) of 1176 tested positive for HIV. Of those who tested positive, based on self-report, 119 (48%; 95% CI 42-54) reported knowing their HIV status, of whom 112 (94%; 88-98) reported using antiretroviral therapy (ART), of whom 89 (79%; 71-87) had viral load suppression. Based on viral load recategorisation, 180 (73%; 67-78) of 248 MSM testing HIV positive reported knowing their HIV status, of whom 174 (97%; 93-99) reported using ART, of whom 151 (87%; 81-91) had viral load suppression. 92 (28%; 23-33) of 335 transgender women and genderqueer individuals tested positive for HIV. Based on self-reports from these individuals 34 (37%; 27-48) of 92 participants reported knowing their HIV status, of whom 31 (91%; 76-98) reported using ART, of whom 27 (87%; 70-96%) had viral load suppression. Based on viral load recategorisation of data from transgender women and genderqueer participants, 53 (58%; 47-58) of 92 reported awareness of their HIV status, of whom 50 (94%; 84-99) reported using ART, of whom 46 (92%; 81-98) had viral load suppression. HIV-positive MSM aged 18-24 years had lower odds of being aware of their status than those aged at least 35 years (adjusted odds ratio [aOR] 0·34; 95% CI 0·13-0·92), as did HIV-positive MSM aged 25-34 years (aOR 0·26; 0·12-0·56). HIV-positive MSM aged 18-24 years also had a lower odds of having viral load suppression than those aged 35 years and older (aOR 0·35; 0·16-0·78), as did those aged 25-34 years (aOR 0·36; 0·19-0·67). No factors were significantly associated with awareness among transgender women and genderqueer individuals in multivariable models. INTERPRETATION: Our survey showed that HIV prevalence was high and the largest difference between our results and the 90-90-90 treatment targets was in HIV status awareness, indicating the need for improvements in engaging MSM (especially young MSM), transgender women, and genderqueer individuals in HIV testing services.

RESUMEN

Introduction: Community health workers (CHWs) play an integral role in Sierra Leone's health systems strengthening efforts. Our goal was to understand CHWs' experiences of providing immunization and malaria prevention services in urban settings and explore opportunities to optimize their contributions to these services. Methods: In 2018, we conducted an exploratory qualitative assessment in the Western Area Urban district, which covers most of the capital city of Freetown. We purposively selected diverse health facilities (i.e., type, ownership, setting) and recruited CHWs through their supervisors. We conducted eight focus group discussions (FGD) with CHWs, which were audio-recorded. The topics explored included participants' background, responsibilities and priorities of urban CHWs, sources of motivation at work, barriers to CHWs' immunization and malaria prevention activities, and strategies used to address these barriers. The local research team transcribed and translated FGDs into English; then we used qualitative content analysis to identify themes. Results: Four themes emerged from the qualitative content analysis: (1) pride, compassion, recognition, and personal benefits are important motivating factors to keep working as CHWs; (2) diverse health responsibilities and competing priorities result in overburdening of CHWs; (3) health system- and community-level barriers negatively affect CHWs' activities and motivation; (4) CHWs use context-specific strategies to address challenges in their work but require further support. Conclusion: Focused support for CHWs is needed to optimize their contributions to immunization and malaria prevention activities. Such interventions should be coupled with systems-level efforts to address the structural barriers that negatively affect CHWs' overall work and motivation, such as the shortage of work supplies and the lack of promised financial support.
