"It went through the roof": an observation study exploring the rise in PrEP uptake among Zimbabwean female sex workers in response to adaptations during Covid-19

INTRODUCTION: Sisters with a Voice (Sisters), a programme providing community-led differentiated HIV prevention and treatment services, including condoms, HIV testing, pre-exposure prophylaxis (PrEP) and antiretroviral therapy linkage for sex workers, reached over 26,000 female sex workers (FSW) across Zimbabwe in 2020. Zimbabwe's initial Covid "lockdown" in March 2020 and associated movement restrictions interrupted clinical service provision for 6 weeks, particularly in mobile clinics, triggering the adaptation of services for the Covid-19 context and a scale up of differentiated service delivery (DSD) models. PrEP service delivery decentralized with shifts from clinical settings towards community/home-based, peer-led PrEP services to expand and maintain access. We hypothesize that peer-led community-based provision of PrEP services influenced both demand and supply-side determinants of PrEP uptake. We observed the effect of these adaptations on PrEP uptake among FSW accessing services in Sisters in 2020. METHODS: New FSW PrEP initiations throughout 2020 were tracked by analysing routine Sisters programme data and comparing it with national PrEP initiation data for 2020. We mapped PrEP uptake among all negative FSW attending services in Sisters alongside Covid-19 adaptations and shifts in the operating environment throughout 2020: prior to lockdown (January-March 2020), during severe restrictions (April-June 2020), subsequent easing (July-September 2020) and during drug stockouts that followed (October-December 2020). RESULTS AND DISCUSSION: PrEP uptake in 2020 occurred at rates <25% (315 initiations or fewer) per month prior to the emergence of Covid-19. In response to Covid-19 restrictions, DSD models were scaled up in April 2020, including peer demand creation, community-based delivery, multi-month dispensing and the use of virtual platforms for appointment scheduling and post-PrEP initiation support. Beginning May 2020, PrEP uptake increased monthly, peaking at an initiation rate of 51% (n = 1360) in September 2020. Unexpected rise in demand coincided with national commodity shortages between October and December 2020, resulting in restriction of new initiations with sites prioritizing refills. CONCLUSIONS: Despite the impact of Covid-19 on the Sisters Programme and FSW mobility, DSD adaptations led to a large increase in PrEP initiations compared to pre-Covid levels demonstrating that a peer-led, community-based PrEP service delivery model is effective and can be adopted for long-term use

Interpreting declines in HIV test positivity: an analysis of routine data from Zimbabwe's national sex work programme, 2009–2019

Introduction Early diagnosis of HIV is critical for epidemic control. To achieve this, successful testing programmes are essential and test positivity is often used as a marker of their performance. The aim of this study was to analyse trends and predictors of HIV test positivity over time and explore how an understanding of seroconversion rates could build on our interpretation of this indicator among female sex workers in Zimbabwe. Methods We analysed HIV test data from Zimbabwe's nationally scaled sex work programme between 2009 and 2019. We defined test positivity as the proportion of all tests that were HIV positive and measured new diagnoses by estimating seroconversion rates among women with repeat tests, defined as an HIV-positive test after at least one HIV-negative test in the programme. We used logistic regression to analyse test positivity over three time-periods: 2009–2013, 2014–2017 and 2018–2019, adjusting for potential confounding by demographic factors and the mediating effects of time since last HIV test. We calculated the seroconversion rates for the same time-periods. Results During the 10-year study period, 54,503 tests were recorded in 39,462 women. Between 2009 and 2013, 18% of tests were among women who reported testing in the previous 6 months. By 2018–2019, this had increased to 57%. Between 2018 and 2019, test positivity was 9.6%, compared to 47.9% for 2009–2013 (aOR 6.08 95% CI 5.52–6.70) and 18.8% for 2014–2017 (aOR 2.17 95% CI 2.06–2.28). Adjusting for time since last test reduced effect estimates for 2009–2013 (aOR 4.03 95% CI 3.64–4.45) and 2014–2017 (aOR 1.97 95% CI 1.86–2.09) compared to 2018–2019. Among 7573 women with an initial HIV-negative test in the programme and at least one subsequent test, 464 tested HIV positive at a rate of 3.9 per 100 pyar (95% CI 3.5–4.2). Conclusions Test positivity decreased among women testing through the programme over time, while seroconversion rates remained high. These declines were partly driven by changes in individual testing history, reflecting comprehensive coverage of testing services and greater knowledge of HIV status, but not necessarily declining rates of seroconversion. Understanding testing history and monitoring new HIV infections from repeat tests could strengthen the interpretation of test positivity and provide a better understanding of programme performance

Sequential screening for lung cancer in a high-risk group: randomised controlled trial: LungSEARCH: a randomised controlled trial of Surveillance using sputum and imaging for the EARly detection of lung Cancer in a High-risk group.

BACKGROUND: Low-dose computed tomography (LDCT) screening detects early-stage lung cancer and reduces mortality. We proposed a sequential approach targeted to a high-risk group as a potentially efficient screening strategy. METHODS: LungSEARCH was a national multicentre randomised trial. Current/ex-smokers with mild/moderate chronic obstructive pulmonary disease (COPD) were allocated (1:1) to have 5 years surveillance or not. Screened participants provided annual sputum samples for cytology and cytometry, and if abnormal were offered annual LDCT and autofluorescence bronchoscopy (AFB). Those with normal sputum provided annual samples. The primary end-point was the percentage of lung cancers diagnosed at stage I/II (nonsmall cell) or limited disease (small cell). RESULTS: 1568 participants were randomised during 2007-2011 from 10 UK centres. 85.2% of those screened provided an adequate baseline sputum sample. There were 42 lung cancers among 785 screened individuals and 36 lung cancers among 783 controls. 54.8% (23 out of 42) of screened individuals versus 45.2% (14 out of 31) of controls with known staging were diagnosed with early-stage disease (one-sided p=0.24). Relative risk was 1.21 (95% CI 0.75-1.95) or 0.82 (95% CI 0.52-1.31) for early-stage or advanced cancers, respectively. Overall sensitivity for sputum (in those randomised to surveillance) was low (40.5%) with a cumulative false-positive rate (FPR) of 32.8%. 55% of cancers had normal sputum results throughout. Among sputum-positive individuals who had AFB, sensitivity was 45.5% and cumulative FPR was 39.5%; the corresponding measures for those who had LDCT were 100% and 16.1%, respectively. CONCLUSIONS: Our sequential strategy, using sputum cytology/cytometry to select high-risk individuals for AFB and LDCT, did not lead to a clear stage shift and did not improve the efficiency of lung cancer screening

Integrating Traditional African Education into Current Educational Practices: Suggestions for Primary School Pedagogy Integrating Traditional African Education into Current Educational Practices: Suggestions for Primary School Pedagogy 1

ABSTRACT This paper examines how traditional African educational approaches can be used with European methods in the teaching of young children at primary schools in Zimbabwe. From an African-centred perspective, European/Western education is viewed as &apos;compartmentalistic&apos;, limiting and potentially inhibitive of the communal, social, and cultural responsibilities expected of a fully initiated African adult. The paper takes the position that a re-look at African traditional knowledge dissemination system such as communal education, group learning, fireside folktales and legends, used in tandem with the European paradigm, will produce a better-cultured adult who fits comfortably in the frame of current developments on the African continent. The paper proposes a curriculum that recognises the value of African traditions as educational methods of teaching that can make learning more relevant and exciting for primary school going pupils

Growth Effects of Foreign Direct Investments in Zimbabwe: Do Sources Matter?

The study investigated foreign direct investment (FDI) growth effects in Zimbabwe using data spanning 1990-2019. FDI-led growth theories often view FDI as an enabler of economic growth. However, the extent may depend upon the source of FDI. Nonetheless, existing studies on Zimbabwe base their conclusions on aggregate FDI. Accordingly, we provide fresh evidence by disaggregating FDI inflows by sources. This is logical given the reality that FDI from different sources is heterogeneous. We used the Autoregressive-Distributed-Lag (ARDL) technique to estimate a time series model derived from neoclassical and endogenous growth models. Results indicated that FDI has a significantly positive growth effect. More importantly, we document that FDI sources do matter greatly. Specifically, FDI flows from Africa and Asia were found to have positive and significant growth effects. However, FDI from Europe and the United States has negative and insignificant impacts. We proffer two recommendations. Zimbabwe should attract more FDI from economies/regions in the vicinity of its level of development. Accordingly, Zimbabwe should rationally embrace the recently launched AfCFTA. It is vital to strike a balance between market deepening and promoting domestic production. Also, while most FDI from Asia is from is China, we urge Zimbabwe to provide a conducive environment to investors from the rest of Asia. This can be achieved through signing bilateral FDI agreements with Asian countries.&nbsp;&nbsp
