Background: Differentiating risk for HIV infection is important for providing focussed prevention options to individuals. We conducted a longitudinal study to validate a risk-differentiation tool for predicting HIV or HSV-2 acquisition among HIV-negative youth., Setting: Population-based household survey in east Zimbabwe., Methods: HIV and HSV-2 status and HIV behavioural risk factors were assessed in two surveys conducted 12 months apart among young people. Associations between risk-behaviours and combined HIV/HSV-2 incident infection were estimated using proportional hazards models. We calculated the sensitivity and specificity of risk-differentiation questions in predicting HIV/HSV-2 acquisition and quantified changes between surveys among low, medium, and high-risk categories., Results: In total, 44 HIV/HSV-2 seroconversions were observed in 1812 person-years of follow up (2.43/100PY, 95%CI: 1.71-3.15); 50% of incident cases reported never having had sex at baseline. Risk of HIV/HSV-2 acquisition was higher for those reporting non-regular partners (women: HR=2.71, 95% CI:1.12-6.54, men: HR=1.37, 95%CI: 0.29-6.38) and those reporting having a partner with a sexually transmitted infection (STI) (HR=7.62 (1.22-47.51). Adding a question on non-regular partnerships increased tool sensitivity from 18.2% to 38.6%, and further to 77.3% when restricted to those who had ever had sex. Individual risk category increased for 28% of men and 17% of women over 12-months., Conclusion: The refined risk differentiation tool identified a high proportion of youth at risk of HIV acquisition. Despite this, half of incident infections were among individuals who reported no prior sexual activity. The shifting patterns of risk behaviours underscore the need for dynamic prevention engagement strategies in high HIV prevalence or incidence settings., Competing Interests: Conflicts of Interest SG declares shareholdings in pharmaceutical companies GlaxoSmithKline and Astra Zeneca.

Introduction: in 2016, the partner-funded Smart-LyncAges participatory learning project explored the feasibility of a youth-friendly package including incentivized peer educators (PEs) to enhance adolescent sexual and reproductive health (ASRH) and voluntary medical male circumcision (VMMC) linkages. After 12 months of implementation, funding reduction resulted in reduced direct project monitoring and discontinuation of monetary incentives for PEs. We assessed if reduced funding after one year of implementation affected the performance and retention of PEs and uptake of VMMC and HIV testing in ASRH services by adolescents in Bulawayo City (urban) and Mount (Mt) Darwin District (rural) in Zimbabwe., Methods: our study was an ecological study using routine data collected from March 2016 to February 2017 (intensive support) and March 2017 to February 2018 (reduced support). All the ASRH and VMMC sites in Mt Darwin and Bulawayo were involved. Participants included 58 PEs and all adolescents accessing VMMC and ASRH services. Retention of PEs measured by the submission of monthly reports and uptake of VMMC and HIV testing were the primary outcome measures., Results: the Smart-LyncAges project engaged 58 PEs with 80% aged 20-24 years. Two-thirds were male and 60% were engaged in peer education before the project. Retention of PEs was not negatively affected by funding reduction, with 70% retained up to 11 months after funding reduction. However, their performance, measured by submission of monthly activity reports and the number of adolescents reached with VMMC and HIV messages, declined while uptake of both VMMC and HIV testing was sustained., Conclusion: sustained uptake of services was possibly due to heightened awareness of service availability and demand generation in the first year of implementation. Peer-led interventions are effective for health information dissemination. Monetary incentives determine performance, but are not the only reason for retention., Competing Interests: The authors declare no competing interest., (Copyright: Simbarashe Mabaya.)

Zimbabwe has a high burden of HIV (i.e., estimated 1.3 million HIV-infected and 13.8% HIV incidence in 2017). In 2017, the country developed and implemented a pilot of HIV case surveillance (CS) based on the 2017 World Health Organisation (WHO) person-centred HIV patient monitoring (PM) and case surveillance guidelines. At the end of the pilot phase an evaluation was conducted to inform further steps. The pilot was conducted in two districts (i.e., Umzingwane in Matabeleland South Province and Mutare in Manicaland Province) from August 2017 to December 2018. A mixed-methods cross-sectional study of stakeholders and health facility staff was used to assess the design and operations, performance, usefulness, sustainability, and scalability of the CS system. A total of 13 stakeholders responded to an online questionnaire, while 33 health facility respondents were interviewed in 11 health facilities in the two districts. The HIV CS system was adequately designed for Zimbabwe's context, integrated within existing health information systems at the facility level. However, the training was minimal, and an opportunity to train the data entry clerks in data analysis was missed. The system performed well in terms of surveillance and informatics attributes. However, viral load test results return was a significant problem. The HIV CS system was found useful at the health facility level and should be rolled out in a phased manner, beginning in Manicaland and Matabeleland South provinces. An electronic link needs to be made between the health facilities and the laboratory to reduce viral load test results delays., Competing Interests: The authors declare no competing interests., (Copyright: Peter Nsubuga et al.)

Objectives: WHO recommended strengthening the linkages between various HIV prevention programmes and adolescent sexual reproductive health (ASRH) services. The Smart-LyncAges project piloted in Bulawayo city and Mt Darwin district of Zimbabwe established a referral system to link the voluntary medical male circumcision (VMMC) clients to ASRH services provided at youth centres. Since its inception in 2016, there has been no assessment of the performance of the referral system. Thus, we aimed to assess the proportion of young (10-24 years) VMMC clients getting 'successfully linked' to ASRH services and factors associated with 'not being linked'., Design: This was a cohort study using routinely collected secondary data., Setting: All three VMMC clinics of Mt Darwin district and Bulawayo province., Primary Outcome Measures: The proportion of 'successfully linked' was summarised as the percentage with a 95% CI. Adjusted relative risks (aRR) using a generalised linear model was calculated as a measure of association between client characteristics and 'not being linked'., Results: Of 1773 young people registered for VMMC services, 1478 (83%) were referred for ASRH services as they had not registered for ASRH previously. Of those referred for ASRH services, the mean (SD) age of study participants was 13.7 (4.3) years and 427 (28.9%) were out of school. Of the referred, 463 (31.3%, 95% CI: 30.0 to 33.8) were 'successfully linked' to ASRH services and the median (IQR) duration for linkage was 6 (0-56) days. On adjusted analysis, receiving referral from Bulawayo circumcision clinic (aRR: 1.5 (95% CI: 1.3 to 1.7)) and undergoing circumcision at outreach sites (aRR: 1.2 (95% CI: 1.1 to 1.3)) were associated with 'not being linked' to ASRH services., Conclusion: Linkage to ASRH services from VMMC is feasible as one-third VMMC clients were successfully linked. However, there is need to explore reasons for not accessing ASRH services and take corrective actions to improve the linkages., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Objectives: Antiretroviral therapy (ART) and isoniazid preventive therapy (IPT) are known to have a tuberculosis (TB) protective effect at the individual level among people living with HIV (PLHIV). In Zimbabwe where TB is driven by HIV infection, we have assessed whether there is a population-level association between IPT and ART scale-up and annual TB case notification rates (CNRs) from 2000 to 2018., Design: Ecological study using aggregate national data., Setting: Annual aggregate national data on TB case notification rates (stratified by TB category and type of disease), numbers (and proportions) of PLHIV in ART care and of these, numbers (and proportions) ever commenced on IPT., Results: ART coverage in the public sector increased from <1% (8400 PLHIV) in 2004 to ~88% (>1.1 million PLHIV patients) by December 2018, while IPT coverage among PLHIV in ART care increased from <1% (98 PLHIV) in 2012 to ~33% (373 917 PLHIV) by December 2018. These HIV-related interventions were associated with significant declines in TB CNRs: between the highest CNR prior to national roll-out of ART (in 2004) to the lowest recorded CNR after national IPT roll-out from 2012, these were (1) for all TB case (510 to 173 cases/100 000 population; 66% decline, p<0.001); (2) for those with new TB (501 to 159 cases/100 000 population; 68% decline, p<0.001) and (3) for those with new clinically diagnosed PTB (284 to 63 cases/100 000 population; 77.8% decline, p<0.001)., Conclusions: This study shows the population-level impact of the continued scale-up of ART among PLHIV and the national roll-out of IPT among those in ART care in reducing TB, particularly clinically diagnosed TB which is largely associated with HIV. There are further opportunities for continued mitigation of TB with increasing coverage of ART and in particular IPT which still has a low coverage., Competing Interests: Competing interests: Technical support was provided through the International Union Against Tuberculosis and Lung Disease (IUATLD).

Objective: Peer education is an intervention within the voluntary medical male circumcision (VMMC)-adolescent sexual reproductive health (ASRH) linkages project in Bulawayo and Mount Darwin, Zimbabwe since 2016. Little is known if results extend beyond increasing knowledge. We therefore assessed the extent of and factors affecting referral by peer educators and receipt of HIV testing services (HTS), contraception, management of sexually transmitted infections (STIs) and VMMC services by young people (10-24 years) counselled., Design: A cohort study involving all young people counselled by 95 peer educators during October-December 2018, through secondary analysis of routinely collected data., Setting: All ASRH and VMMC sites in Mt Darwin and Bulawayo., Participants: All young people counselled by 95 peer educators., Outcome Measures: Censor date for assessing receipt of services was 31 January 2019. Factors (clients' age, gender, marital and schooling status, counselling type, location, and peer educators' age and gender) affecting non-referral and non-receipt of services (dependent variables) were assessed by log-binomial regression. Adjusted relative risks (aRRs) were calculated., Results: Of the 3370 counselled (66% men), 65% were referred for at least one service. 58% of men were referred for VMMC. Other services had 5%-13% referrals. Non-referral for HTS decreased with clients' age (aRR: ~0.9) but was higher among group-counselled (aRR: 1.16). Counselling by men (aRR: 0.77) and rural location (aRR: 0.61) reduced risks of non-referral for VMMC, while age increased it (aRR ≥1.59). Receipt of services was high (64%-80%) except for STI referrals (39%). Group counselling and rural location (aRR: ~0.52) and male peer educators (aRR: 0.76) reduced the risk of non-receipt of VMMC. Rural location increased the risk of non-receipt of contraception (aRR: 3.18) while marriage reduced it (aRR: 0.20)., Conclusion: We found varying levels of referral ranging from 5.1% (STIs) to 58.3% (VMMC) but high levels of receipt of services. Type of counselling, peer educators' gender and location affected receipt of services. We recommend qualitative approaches to further understand reasons for non-referrals and non-receipt of services., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Study Goals: To describe the differences between clients presenting after rape and clients who have consented to sex as a minor to an SGBV clinic in Harare, Zimbabwe, and how these differences affect their care requirements., Background: Adolescents and adults presenting at the specialized Sexual and Gender Based Violence clinic in Harare are offered a standardised package of free medical and psychosocial care. Zimbabwe has an HIV prevalence of 14%, so prevention of HIV infection using PEP for those that present within 72 hours is a key part of the response. STI treatment, emergency contraceptive pills, referral for termination of pregnancy, psychological, social and legal support is also provided., Methods: This is a retrospective descriptive study of routine programmatic data collected at the Edith Opperman polyclinic in Mbare SGBV clinic from 2011 to 2014. Chi-square tests and logistic regression were used to describe the different experiences and the differences in uptake of care between clients presenting for rape compared to those who consented to sex as a minor., Results: During the study period a total of 3617 clients presented to the clinic. 2242 (62%) sought care after rape, 602 (17%) for having consented to sex as a minor and 395 (11%) for suspected sexual abuse. 1615 (45%) of people presenting were 12-15 year olds. Minors who consented to sex compared to survivors of rape were less likely to report within 72 hours- 156 (26%) vs 894 (40%) p<0.001; less likely to report that they delayed due to fear- 68 (17%) vs 472 (40%) p<0.001, less likely to have experienced accompanying violence- 9 (1%) vs 176 (8%) p<0.001 or physical trauma-34 (6%) vs 427 (19%) p<0.001; and less likely to display psychological symptoms at presentation 51 (8%) vs 411 (18%) p<0.001. Minors who consented to sex compared to those who were raped were less likely to start PEP if eligible-123 (80%) vs 751 (93%) p<0.001, less likely to take emergency contraceptives if eligible-125 (81%) vs 598 (88%) p<0.001, more likely to be pregnant- 132 (23%) vs 241 (15%) p<0.001; less likely to request a termination of pregnancy if pregnant-10 (8%) vs 74 (31%) p<0.001; and less likely to come for at least one follow up 281 (47%) vs 1304 (58%) p<0.001., Conclusion: The experiences of those who consent to sex as a minor and those that have experienced forced sex were very different. The standardised SGBV medical response does not fully meet the needs to protect minors who have consented to sex from HIV or unwanted pregnancies. Clients who present for having consented to sex as a minor might benefit more from being offered long-term family planning or being assessed as a sero-discordant couple rather than simply PEP and ECP as is relevant for clients who have been raped. More provision of health care is needed for minors to ensure they have access to enough information and protection from HIV, other STIs and unwanted pregnancy, before they decide to engage in sexual intercourse, rather than as an emergency at an SGBV clinic.
