Factors Associated with Having both Male and Female Recent Sexual Partnerships Among Men Who Have Sex with Men in Harare and Bulawayo, Zimbabwe.

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.

Presence of tuberculosis symptoms among HIV-positive men who have sex with men (MSM) in Zimbabwe.

We conducted secondary data analysis using a biobehavioral survey dataset of 1538 MSM from Zimbabwe. Survey participants were screened for the four symptoms suggestive of tuberculosis infection using the WHO TB screening algorithm. Results: All participants experienced at least one symptom suggestive of tuberculosis. 40% of HIV-positive MSM reported having had a cough in the last month and 13% of them experienced unexpected weight loss. The prevalence of experiencing any of the four TB symptoms amongst HIV-positive MSM was 23%. Contribution There is an urgent need for active TB case finding and treatment amongst HIV-positive MSM in Zimbabwe. Clinicians will need to ensure that MSM who need TB testing receive it timeously.

Risk Factors for Recent HIV Infections among Adults in 14 Countries in Africa Identified by Population-Based HIV Impact Assessment Surveys, 2015-2019.

Identifying persons who have newly acquired HIV infections is critical for characterizing the HIV epidemic direction. We analyzed pooled data from nationally representative Population-Based HIV Impact Assessment surveys conducted across 14 countries in Africa for recent infection risk factors. We included adults 15-49 years of age who had sex during the previous year and used a recent infection testing algorithm to distinguish recent from long-term infections. We collected risk factor information via participant interviews and assessed correlates of recent infection using multinomial logistic regression, incorporating each survey's complex sampling design. Compared with HIV-negative persons, persons with higher odds of recent HIV infection were women, were divorced/separated/widowed, had multiple recent sex partners, had a recent HIV-positive sex partner or one with unknown status, and lived in communities with higher HIV viremia prevalence. Prevention programs focusing on persons at higher risk for HIV and their sexual partners will contribute to reducing HIV incidence.

Applying mathematical modelling to estimate the impact of COVID-19-related VMMC service disruptions on new HIV infections in Zimbabwe.

BACKGROUND: The COVID-19 pandemic has overwhelmed health systems with knock on effects on diagnosis, treatment, and care. To mitigate the impact, the government of Zimbabwe enforced a strict lockdown beginning 30 March 2020 which ran intermittently until early 2021. In this period, the Ministry of Health and Childcare strategically prioritized delivery of services leading to partial and full suspension of services considered non-essential, including HIV prevention. As a result, Voluntary Medical Male Circumcision (VMMC) services were disrupted leading to an 80% decline in circumcisions conducted in 2020. Given the efficacy of VMMC, we quantified the potential effects of VMMC service disruption on new HIV infections in Zimbabwe. METHODS: We applied the GOALS model to evaluate the impact of COVID-19-related disruptions on reducing new HIV infections over 30-years. GOALS is an HIV simulation model that estimates number of new HIV infections based on sexual behaviours of population groups. The model is parameterized based on national surveys and HIV program data. We hypothesized three coverage scenarios by 2030: scenario I - pre-COVID trajectory: 80% VMMC coverage; Scenario II - marginal COVID-19 impact: 60% VMMC coverage, and scenario III - severe COVID-19 impact: 45% VMMC coverage. VMMC coverage between 2020 and 2030 was linearly interpolated to attain the estimated coverage and then held constant from 2030 to 2050, and discounted outcomes at 3%. RESULTS: Compared to the baseline scenario I, in scenario II, we estimated that the disruption of VMMC services would generate an average of 200 (176-224) additional new infections per year and 7,200 new HIV infections over the next 30 years. For scenario III, we estimated an average of 413 (389-437) additional new HIV infections per year and 15,000 new HIV infections over the next 30 years. The disruption of VMMC services could generate additional future HIV treatment costs ranging from $27 million to $55 million dollars across scenarios II and III, respectively. CONCLUSION: COVID-19 disruptions destabilized delivery of VMMC services which could contribute to an additional 7,200 new infections over the next 30 years. Unless mitigated, these disruptions could derail the national goals of reducing new infections by 2030.

Peer-led counselling with problem discussion therapy for adolescents living with HIV in Zimbabwe: A cluster-randomised trial.

BACKGROUND: Adolescents living with HIV have poor virological suppression and high prevalence of common mental disorders (CMDs). In Zimbabwe, the Zvandiri adolescent peer support programme is effective at improving virological suppression. We assessed the effect of training Zvandiri peer counsellors known as Community Adolescent Treatment Supporters (CATS) in problem-solving therapy (PST) on virological suppression and mental health outcomes. METHODS AND FINDINGS: Sixty clinics were randomised 1:1 to either normal Zvandiri peer counselling or a peer counsellor trained in PST. In January to March 2019, 842 adolescents aged 10 to 19 years and living with HIV who screened positive for CMDs were enrolled (375 (44.5%) male and 418 (49.6%) orphaned of at least one parent). The primary outcome was virological nonsuppression (viral load ≥1,000 copies/mL). Secondary outcomes were symptoms of CMDs measured with the Shona Symptom Questionnaire (SSQ ≥8) and depression measured with the Patient Health Questionnaire (PHQ-9 ≥10) and health utility score using the EQ-5D. The adjusted odds ratios (AORs) and 95% confidence intervals (CIs) were estimated using logistic regression adjusting for clinic-level clustering. Case reviews and focus group discussions were used to determine feasibility of intervention delivery. At baseline, 35.1% of participants had virological nonsuppression and 70.3% had SSQ≥8. After 48 weeks, follow-up was 89.5% for viral load data and 90.9% for other outcomes. Virological nonsuppression decreased in both arms, but there was no evidence of an intervention effect (prevalence of nonsuppression 14.7% in the Zvandiri-PST arm versus 11.9% in the Zvandiri arm; AOR = 1.29; 95% CI 0.68, 2.48; p = 0.44). There was strong evidence of an apparent effect on common mental health outcomes (SSQ ≥8: 2.4% versus 10.3% [AOR = 0.19; 95% CI 0.08, 0.46; p < 0.001]; PHQ-9 ≥10: 2.9% versus 8.8% [AOR = 0.32; 95% CI 0.14, 0.78; p = 0.01]). Prevalence of EQ-5D index score <1 was 27.6% versus 38.9% (AOR = 0.56; 95% CI 0.31, 1.03; p = 0.06). Qualitative analyses found that CATS-observed participants had limited autonomy or ability to solve problems. In response, the CATS adapted the intervention to focus on empathic problem discussion to fit adolescents' age, capacity, and circumstances, which was beneficial. Limitations include that cost data were not available and that the mental health tools were validated in adult populations, not adolescents. CONCLUSIONS: PST training for CATS did not add to the benefit of peer support in reducing virological nonsuppression but led to improved symptoms of CMD and depression compared to standard Zvandiri care among adolescents living with HIV in Zimbabwe. Active involvement of caregivers and strengthened referral structures could increase feasibility and effectiveness. TRIAL REGISTRATION: Pan African Clinical Trials Registry PACTR201810756862405.

High Burden of Active Syphilis and Human Immunodeficiency Virus/Syphilis Coinfection Among Men Who Have Sex With Men, Transwomen, and Genderqueer Individuals in Zimbabwe.

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.

Stigma, Social Cohesion, and HIV Risk Among Sexual and Gender Minorities in Two Cities in Zimbabwe.

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.

Improving access to pre-exposure prophylaxis for adolescent girls and young women: recommendations from healthcare providers in eastern Zimbabwe.

BACKGROUND: In sub-Saharan Africa, adolescent girls and young women (AGYW) are at high risk of acquiring HIV. A growing number of sub-Saharan African countries are beginning to avail pre-exposure prophylaxis, or PrEP, but with limited success. Unpacking strategies to overcome barriers to the uptake of PrEP is critical to prevent HIV amongst AGYW. This article explores health professionals' views and recommendations on what is required to increase uptake of PrEP. METHODS: The study draws on interview data from 12 providers of HIV prevention services in eastern Zimbabwe. The healthcare providers were purposefully recruited from a mix of rural and urban health facilities offering PrEP. The interviews were transcribed and imported into NVivo 12 for thematic coding and network analysis. RESULTS: Our analysis revealed six broad strategies and 15 concrete recommendations which detail the range of elements healthcare providers consider central for facilitating engagement with PrEP. The healthcare providers called for: (1) PrEP marketing campaigns; (2) youth-friendly services or corners; (3) improved PrEP delivery mechanisms; (4) improvements in PrEP treatment; (5) greater engagement with key stakeholders, including with young people themselves; and (6) elimination of costs associated with PrEP use. These recommendations exemplify an awareness amongst healthcare providers that PrEP access is contingent on a range of factors both inside and outside of the clinical setting. CONCLUSIONS: Healthcare providers are at the frontline of the HIV epidemic response. Their community-embeddedness, coupled with their interactions and encounters with AGYW, make them well positioned to articulate context-specific measures for improving access to PrEP. Importantly, the breadth of their recommendations suggests recognition of PrEP use as a complex social practice that requires integration of a combination of interventions, spanning biomedical, structural, and behavioural domains.

Interrupted Access to and Use of Family Planning Among Youth in a Community-Based Service in Zimbabwe During the First Year of the COVID-19 Pandemic.

The COVID-19 pandemic has had serious impacts on economic, social, and health systems, and fragile public health systems have become overburdened in many countries, exacerbating existing service delivery challenges. This study describes the impact of the COVID-19 pandemic on family planning services within a community-based integrated HIV and sexual and reproductive health intervention for youth aged 16-24 years being trialled in Zimbabwe (CHIEDZA). It examines the experiences of health providers and clients in relation to how the first year of the pandemic affected access to and use of contraceptives.

The impact of the COVID-19 pandemic on people living with HIV in Zimbabwe.

The COVID-19 pandemic was reported from March 2020 in Zimbabwe. COVID-19 containment measures which included repeated lockdowns have disrupted community interactions, reduced working hours, restricted travel and restricted HIV services for people living with HIV (PLHIV), among others. The study adopted a cross-sectional design. Both qualitative and quantitative data were collected in all the 10 provinces and analysed. A sample size of 480 was calculated for the cross-sectional survey. Secondary data on HIV early warning indicators from 2018 to 2021 were extracted from 20 randomly selected health facilities and used for modelling. Mathematical modelling was conducted to assess the impact of COVID-19 on PLHIV. AIDS-related deaths increased from 20 100 in 2019 to 22 200 in 2020. In addition, there were significant years of life lost (yLLs) from premature mortality and years of life lost due to disability (yLDs) from COVID-19. Prevalence of COVID-19 among PLHIV was 4%. COVID-19 vaccination coverage was 64%, which is higher than the national average of 42%. Stress and breach of confidentiality as ARV medicines were given out in open spaces and fear of contracting COVID-19 were the perceived psychological issues. COVID-19 disrupted HIV service provision, increased AIDS-related deaths and caused psychological challenges.

Economic implications of COVID-19 for the HIV epidemic and the response in Zimbabwe.

Understanding the economic implications of COVID-19 for the HIV epidemic and response is critical for designing policies and strategies to effectively sustain past gains and accelerate progress to end these colliding pandemics. While considerable cross-national empirical evidence exists at the global level, there is a paucity of such deep-dive evidence at national level. This article addresses this gap. While Zimbabwe experienced fewer COVID-19 cases and deaths than most countries, the pandemic has had profound economic effects, reducing gross domestic product by nearly 7% in 2020. This exacerbates the long-term economic crisis that began in 1998. This has left many households vulnerable to the economic fallout from COVID-19, with the number of the extreme poor having increased to 49% of the population in 2020 (up from 38% in 2019). The national HIV response, largely financed externally, has been one of the few bright spots. Overall, macro-economic and social conditions heavily affected the capacity of Zimbabwe to respond to COVID-19. Few options were available for borrowing the needed sums of money. National outlays for COVID-19 mitigation and vaccination amounted to 2% of GDP, with one-third funded by external donors. Service delivery innovations helped sustain access to HIV treatment during national lockdowns. As a result of reduced access to HIV testing, the number of people initiating HIV treatment declined. In the short term, there are likely to be few immediate health care consequences of the slowdown in treatment initiation due to the country's already high level of HIV treatment coverage. However, a longer-lasting slowdown could impede national progress towards ending HIV and AIDS. The findings suggest a need to finance the global commons, specifically recognising that investing in health care is investing in economic recovery.

Human Immunodeficiency Virus Infection in Adolescents and Mode of Transmission in Southern Africa: A Multinational Analysis of Population-Based Survey Data.

BACKGROUND: Adolescents aged 10-19 years living with human immunodeficiency virus (HIV) (ALHIV), both perinatally infected adolescents (APHIV) and behaviorally infected adolescents (ABHIV), are a growing population with distinct care needs. We characterized the epidemiology of HIV in adolescents included in Population-based HIV Impact Assessments (2015-2017) in Zimbabwe, Malawi, Zambia, Eswatini, and Lesotho. METHODS: Adolescents were tested for HIV using national rapid testing algorithms. Viral load (VL) suppression (VLS) was defined as VL <1000 copies/mL, and undetectable VL (UVL) as VL <50 copies/mL. Recent infection (within 6 months) was measured using a limiting antigen avidity assay, excluding adolescents with VLS or with detectable antiretrovirals (ARVs) in blood. To determine the most likely mode of infection, we used a risk algorithm incorporating recency, maternal HIV and vital status, history of sexual activity, and age at diagnosis. RESULTS: HIV prevalence ranged from 1.6% in Zambia to 4.8% in Eswatini. Of 707 ALHIV, 60.9% (95% confidence interval, 55.3%-66.6%) had HIV previously diagnosed, and 47.1% (41.9%-52.3%) had VLS. Our algorithm estimated that 72.6% of ALHIV (485 of 707) were APHIV, with HIV diagnosed previously in 69.5% of APHIV and 39.4% of ABHIV, and with 65.3% of APHIV and 33.5% of ABHIV receiving ARV treatment. Only 67.2% of APHIV and 60.5% of ABHIV receiving ARVs had UVL. CONCLUSIONS: These findings suggest that two-thirds of ALHIV were perinatally infected, with many unaware of their status. The low prevalence of VLS and UVL in those receiving treatment raises concerns around treatment effectiveness. Expansion of opportunities for HIV diagnoses and the optimization of treatment are imperative.

Screening for HIV Among Patients at Tuberculosis Clinics - Results from Population-Based HIV Impact Assessment Surveys, Malawi, Zambia, and Zimbabwe, 2015-2016.

The World Health Organization and national guidelines recommend HIV testing and counseling at tuberculosis (TB) clinics for all patients, regardless of TB diagnosis (1). Population-based HIV Impact Assessment (PHIA) survey data for 2015-2016 in Malawi, Zambia, and Zimbabwe were analyzed to assess HIV screening at TB clinics among persons who had positive HIV test results in the survey. The analysis was stratified by history of TB diagnosis* (presumptive versus confirmed†), awareness§ of HIV-positive status, antiretroviral therapy (ART)¶ status, and viral load suppression among HIV-positive adults, by history of TB clinic visit. The percentage of adults who reported having ever visited a TB clinic ranged from 4.7% to 9.7%. Among all TB clinic attendees, the percentage who reported that they had received HIV testing during a TB clinic visit ranged from 48.0% to 62.1% across the three countries. Among adults who received a positive HIV test result during PHIA and who did not receive a test for HIV at a previous TB clinic visit, 29.4% (Malawi), 21.9% (Zambia), and 16.2% (Zimbabwe) reported that they did not know their HIV status at the time of the TB clinic visit. These findings represent missed opportunities for HIV screening and linkage to HIV care. In all three countries, viral load suppression rates were significantly higher among those who reported ever visiting a TB clinic than among those who had not (p<0.001). National programs could strengthen HIV screening at TB clinics and leverage them as entry points into the HIV diagnosis and treatment cascade (i.e., testing, initiation of treatment, and viral load suppression).

Forced Sexual Initiation and Early Sexual Debut and Associated Risk Factors and Health Problems Among Adolescent Girls and Young Women - Violence Against Children and Youth Surveys, Nine PEPFAR Countries, 2007-2018.

Adolescent girls and young women aged 13-24 years are disproportionately affected by HIV in sub-Saharan Africa (1), resulting from biologic, behavioral, and structural* factors, including violence. Girls in sub-Saharan Africa also experience sexual violence at higher rates than do boys (2), and women who experience intimate partner violence have 1.3-2.0 times the odds of acquiring HIV infection, compared with those who do not (3). Violence Against Children and Youth Survey (VACS) data during 2007-2018 from nine countries funded by the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) were analyzed to estimate prevalence and assess factors associated with early sexual debut and forced sexual initiation.† Among adolescent girls and young women aged 13-24 years who ever had sex, the prevalence of lifetime sexual violence ranged from 12.5% to 49.3%, and forced sexual initiation ranged from 14.7% to 38.9%; early sexual debut among adolescent girls and young women aged 16-24 years ranged from 14.4% to 40.1%. In multiple logistic regression models, forced sexual initiation was associated with being unmarried, violence victimization, risky sexual behaviors, sexually transmitted infections (STIs), and poor mental health. Early sexual debut was associated with lower education, marriage, ever witnessing parental intimate partner violence during childhood, risky sexual behaviors, poor mental health, and less HIV testing. Comprehensive violence and HIV prevention programming is needed to delay sexual debut and protect adolescent girls and young women from forced sex.

Early retention among pregnant women on 'Option B + ' in urban and rural Zimbabwe.

BACKGROUND: In 2013, the World Health Organisation (WHO) recommended Option B+ as a strategy to prevent mother-to-child transmission (PMTCT) of HIV. In option B+ , lifelong antiretroviral therapy (ART) is offered to all HIV positive pregnant and breastfeeding women to reduce MTCT rate to less than or equal to 5%. Its success depends on retaining women on ART during pregnancy, delivery and breast-feeding period. There is limited data on early retention on ART among pregnant women in Zimbabwe. We therefore assessed early retention among women on Option B + from antenatal care (ANC) until 6 months post ANC booking and at delivery in Bulawayo city and Mazowe rural district of Zimbabwe. METHODS: We collected data for pregnant women booking for ANC between January and March 2018, comparing early retention among ART naïve women and those already on ART. The two cohorts were followed up for 6 months post ANC booking, and this was done in two districts. Data were collected from routine tools used at facility level which include ANC, delivery and ART registers. The Kaplan-Meier survival analysis was used to estimate retention probabilities at 1, 3 and 6 months post-delivery and for retention at delivery proportions were used. Poisson regression was used to investigate factors associated with non-retention at 6 months post ANC booking. RESULTS: A total of 388 women were included in the study with median age of 29 years (IQR: 25-34). Two-thirds booked in their second trimester. Retention at 3 and 6 months post ANC booking was 84% (95% CI 80-88) and 73% (95% CI 69-78) respectively. At delivery 81% (95% CI 76-84) were retained in care, 18% lost-to-follow-up and 1% transferred out. In this study we did not find marital status, gestation age, facility location, ART status at ANC booking, to be associated with loss to follow-up. CONCLUSION: In this study, we found low retention at 3, 6 months and delivery, a threat to elimination of Mother-to-child Transmission of HIV in Zimbabwe. Our findings emphasize the need for enhanced interventions to improve early retention such as post-test counselling, patient tracing and visit reminders.

Understanding HIV and associated risk factors among religious groups in Zimbabwe.

BACKGROUND: The influence of religion and belief systems is widely recognized as an important factor in understanding of health risk perception and myths in the general fight against the HIV pandemic. This study compares the understanding of HIV risk factors and utilization of some HIV services among religious groups in Zimbabwe. METHODS: We conducted secondary data statistical analysis to investigate the understanding of HIV and associated risk factors among religious groups in Zimbabwe using 2015-2016 Zimbabwe Demographic and Health Survey (ZDHS) data. We began by investigating associations between understanding of HIV and associated risk factors among religious groups. A multivariate stepwise backward elimination method was carried out to explore factors determining understanding of HIV risk after controlling for confounding factors using the most recent ZDHS data (2015-2016). RESULTS: The results from the three surveys showed that, in general apostolic sector had low understanding of HIV and associated risk factors compared to other religious groups. Analysis of the 2015-2016 ZDHS data showed that women belonging to the apostolic sector were less likely to know where to get an HIV test odds ratio (OR) and 95% confidence interval, 0.665 (0.503-0.880) and to know that male circumcision reduces HIV transmission OR 0.863 (0.781-0.955). Women from this group had no knowledge that circumcised men can be infected if they do not use condoms OR 0.633 (0.579-0.693), nor that it is possible for a healthy-looking person to have HIV, OR 0.814 (0.719-0.921). They would not buy vegetables from a vendor with HIV OR 0.817 (0.729-0.915) and were less likely to support that HIV positive children should be allowed to attend school with HIV negative children OR 0.804 (0.680-0.950). Similar results were obtained for men in the apostolic sector. These men also did not agree that women were justified to use condoms if the husband has an Sexually Transmitted Infection (STI) OR 0.851 (0.748-0.967). CONCLUSIONS: Our results suggest that apostolic sector lack adequate knowledge of HIV and associated risk factors than other religious groups. Targeting HIV prevention programmes by religious groups could be an efficient approach for controlling HIV in Zimbabwe.

Impact of Timing of Antiretroviral Treatment and Birth Weight on Mother-to-Child Human Immunodeficiency Virus Transmission: Findings From an 18-Month Prospective Cohort of a Nationally Representative Sample of Mother-Infant Pairs During the Transition From Option A to Option B+ in Zimbabwe.

Background: Preventing mother-to-child transmission of human immunodeficiency virus transmission (MTCT) depends on early initiation of antiretroviral therapy (ART). We report the 18-month MTCT risk during the transition from Option A to Option B+ in Zimbabwe, and assess whether ART preconception could eliminate MTCT in breastfeeding populations. Methods: In 2013, we consecutively recruited a nationally representative sample of 6051 infants aged 4-12 weeks and their mothers from 151 immunization clinics using a multistage stratified cluster sampling method. We identified 1172 human immunodeficiency virus (HIV)-exposed infants and evaluated them at baseline and every 3 months until the child became HIV-infected, died, or reached age 18 months. Results: The cumulative MTCT risk through 18 months postdelivery was 7.0%. Of the HIV-infected mothers, 35.3% started ART preconception, 28.9% during pregnancy, and 9.7% after delivery, and 16.0% received zidovudine during pregnancy. Compared to mothers without antiretroviral drug use, MTCT among those starting ART preconception and during pregnancy was lower by 88% (adjusted hazard ratio [aHR], 0.12; 95% confidence interval [CI], .06-.24) and 75% (aHR, 0.25; 95% CI, .14-.45), respectively. HIV-exposed infants with birth weight <2.5 kg (low birth weight) were 2.6-fold more likely to acquire HIV infection compared to those with birth weight ≥2.5 kg (aHR, 2.57; 95% CI, 1.44-4.59). Controlling for other factors, breastfeeding was not significantly associated with MTCT. Conclusions: ART preconception has the highest impact on reducing MTCT, indicating that HIV-infected, reproductive-age women should be prioritized in "treat-all" strategies. HIV-infected mothers without ART use should be identified at the first immunization visit and treatment initiated to reduce postdelivery MTCT. MTCT risk is higher in mothers with low-birth-weight deliveries.

The Etiology of Male Urethral Discharge in Zimbabwe: Results from the Zimbabwe STI Etiology Study.

INTRODUCTION: Sexually transmitted infections (STIs) are managed syndromically in most developing countries. In Zimbabwe, men presenting with urethral discharge are treated with a single intramuscular dose of kanamycin or ceftriaxone in combination with a week's course of oral doxycycline. This study was designed to assess the current etiology of urethral discharge and other STIs to inform current syndromic management regimens. METHODS: We conducted a study among 200 men with urethral discharge presenting at 6 regionally diverse STI clinics in Zimbabwe. Urethral specimens were tested by multiplex polymerase chain reaction testing for Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium, and Trichomonas vaginalis. In addition, serologic testing for syphilis and HIV was performed. RESULTS: Among the 200 studied men, one or more pathogens were identified in 163 (81.5%) men, including N. gonorrhoeae in 147 (73.5%), C. trachomatis in 45 (22.5%), T. vaginalis in 8 (4.0%), and M. genitalium in 7 (3.5%). Among all men, 121 (60%) had a single infection, 40 (20%) had dual infections, and 2 (1%) had 3 infections. Among the 45 men with C. trachomatis, 36 (80%) were coinfected with N. gonorrhoeae. Overall, 156 (78%) men had either N. gonorrhoeae or C. trachomatis identified. Of 151 men who consented to HIV testing, 43 (28.5%) tested positive. There were no differences in HIV status by study site or by urethral pathogen detected. CONCLUSIONS: Among men presenting at Zimbabwe STI clinics with urethral discharge, N. gonorrhoeae and C. trachomatis are the most commonly associated pathogens. Current syndromic management guidelines seem to be adequate for the treatment for symptomatic men, but future guidelines must be informed by ongoing monitoring of gonococcal resistance.

The Etiology of Genital Ulcer Disease and Coinfections With Chlamydia trachomatis and Neisseria gonorrhoeae in Zimbabwe: Results From the Zimbabwe STI Etiology Study.

BACKGROUND: In many countries, sexually transmitted infections (STIs) are treated syndromically. Thus, patients diagnosed as having genital ulcer disease (GUD) in Zimbabwe receive a combination of antimicrobials to treat syphilis, chancroid, lymphogranuloma venereum (LGV), and genital herpes. Periodic studies are necessary to assess the current etiology of GUD and assure the appropriateness of current treatment guidelines. MATERIALS AND METHODS: We selected 6 geographically diverse clinics in Zimbabwe serving high numbers of STI cases to enroll men and women with STI syndromes, including GUD. Sexually transmitted infection history and risk behavioral data were collected by questionnaire and uploaded to a Web-based database. Ulcer specimens were obtained for testing using a validated multiplex polymerase chain reaction (M-PCR) assay for Treponema pallidum (TP; primary syphilis), Haemophilus ducreyi (chancroid), LGV-associated strains of Chlamydia trachomatis, and herpes simplex virus (HSV) types 1 and 2. Blood samples were collected for testing with HIV, treponemal, and nontreponemal serologic assays. RESULTS: Among 200 GUD patients, 77 (38.5%) were positive for HSV, 32 (16%) were positive for TP, and 2 (1%) were positive for LGV-associated strains of C trachomatis. No H ducreyi infections were detected. No organism was found in 98 (49.5%) of participants. The overall HIV positivity rate was 52.2% for all GUD patients, with higher rates among women compared with men (59.8% vs 45.2%, P < 0.05) and among patients with HSV (68.6% vs 41.8%, P < 0.0001). Among patients with GUD, 54 (27.3%) had gonorrhea and/or chlamydia infection. However, in this latter group, 66.7% of women and 70.0% of men did not have abnormal vaginal or urethral discharge on examination. CONCLUSIONS: Herpes simplex virus is the most common cause of GUD in our survey, followed by T. pallidum. No cases of chancroid were detected. The association of HIV infections with HSV suggests high risk for cotransmission; however, some HSV ulcerations may be due to HSV reactivation among immunocompromised patients. The overall prevalence of gonorrhea and chlamydia was high among patients with GUD and most of them did not meet the criteria for concomitant syndromic management covering these infections.
