Introduction
Beginning in late January 2025, Stop‐Work orders and contract cancellations have disrupted HIV programmes supported by the President's Emergency Plan for AIDS Relief (PEPFAR). We assessed the effects on HIV service delivery in four African countries.
Methods
Weekly aggregate HIV services data from a convenience sample of 165 Center for Disease Control and Prevention (CDC)‐funded, ICAP‐supported facilities—22 in Angola, 75 in the Democratic Republic of the Congo (DRC), 20 in South Sudan and 48 in Zambia—were analysed. We compared data from pre‐Stop‐Work (7 October 2024–23 January 2025), Stop‐Work (24 January 2025–11 February 2025) and post‐resumption (12 February 2025–31 March 2025) phases. We examined the number of individuals: (1) who tested for HIV; (2) receiving index testing; (3) had HIV‐positive results/yield; (4) initiated antiretroviral therapy (ART); as well as (5) number of pregnant women with known HIV status; and (6) number of HIV‐exposed infants who received early infant diagnosis (EID) testing. We used phase‐specific weekly averages, relative percentage changes across phases and linear trend tests to measure the magnitude of disruptions and recovery.
Results
In Angola, DRC and Zambia, significant declines in number of HIV‐positive tests (−58%, −34%, −17%) and ART initiations (−16%, −32%, −17%) were observed across the three phases with limited recovery in number of positive tests in Zambia and ART initiations in Angola. In DRC and Zambia, HIV testing (−33%, −35%), including index testing (−37%, −72%), significantly declined; additionally, HIV testing of pregnant women significantly declined (−28%) in DRC. In Angola and Zambia, EID testing declined (−12%, −18%) with limited recovery. In Angola, HIV testing (2476→2205→2519), including testing for pregnant women (280→ 233→ 287), rebounded in the post‐resumption phase; in DRC, EID (6.5→6.3→7.9) rebounded. There were increases in HIV testing yield in Zambia (2.8%→3.1%→4.0%) and index testing (20→24→36) in Angola. No reductions were observed in South Sudan.
Conclusions
Stop‐Work orders and award terminations have resulted in substantial short‐term reductions in the delivery of HIV testing and treatment services. Long‐term funding disruptions necessitate careful planning, realistic timelines and investment in cost‐effective service models to sustain the gains and maintain the momentum in the global HIV response.

Homebased index case HIV testing (HHTC) has shown higher uptake and good yield than traditional HIV testing methods. World Health Organization has called for increased operational research to evaluate HIV care processes particularly linkage to care. In this paper, we present project results of the time taken to link newly identified PLHIV to care after HHTC in the Manicaland and Midlands provinces of Zimbabwe.
We retrospectively reviewed community-facility referral data from the Zimbabwe HIV Care and Treatment project for newly diagnosed PLHIV for the period March-September 2016. A referral slip was given to a client after receiving a positive HIV results and was presented and filed upon reaching a health facility. In July 2016, the project started working with trained expert clients to assist with linkage to care. Data was entered in a spreadsheet and then imported for descriptive statistical analysis with EpiInfoTM Version 7.2.0.1. Odd ratios were used to identify factors associated with linkage to care within seven days.
Out of 1004 newly identified PLHIV between March and September 2016, 650 (64.7%) were linked to care. The median time taken to be linked to care was four days (Interquartile range 19 days). Overall, 63.1% (410) of PLHIV were linked to care within seven days of diagnosis and 85% within 30 days. PLHIV were more likely to be linked to care within seven days of diagnosis between July and September 2016 (OR = 4.1; p< 0.001), a period when ZHCT started working with expert clients to support linkage to care.
HHTC resulted in almost 63% of newly diagnosed PLHIV being linked into care within seven days, and 85% within 30 days. Linkage to care within seven days was significantly associated with the period of engaging expert clients in the project. We recommend community based HIV testing programs to work with expert clients to ensure timely linkages of new PLHIV.

This study compared the use of pork backfat (PF) and fat-tailed sheep tail and backfat (SF) on the physicochemical, fatty acids and sensory attributes of warthog cabanossi. There were no differences between weight loss during drying, moisture content, pH, water activity, salt content and lipid oxidation between the cabanossi types. However, protein and ash contents were higher in PF cabanossi whilst fat content was higher in SF cabanossi. The PF cabanossi had higher polyunsaturated fatty acids (especially n-6), lower monounsaturated fatty acids whilst the saturated fatty acid content was similar between the two cabanossi products. The n-3:n-6 ratio was more beneficial in the SF cabanossi. The descriptive sensory analysis showed two distinct products where PF cabanossi scored higher for most attributes. Although SF cabanossi scored less for these attributes, this cabanossi had unique and acceptable sensory attributes. This study concluded that fat-tailed sheep tail and backfat could be used to produce a unique cabanossi product of acceptable quality.

Barriers to HIV service utilisation by people living with HIV in two provinces of Zimbabwe : results from 2016 baseline assessment
2018
Background: The emergence of antiretroviral therapy (ART) transformed HIV from a terminal illness to a chronic disease. However, limited access to health services remains one of many barriers to HIV service utilisation by people living with HIV (PLHIV) in low-resource settings. The goal of this study was to describe the barriers to HIV service utilisation in two provinces of Zimbabwe. Methods: A qualitative descriptive study was conducted with PLHIV and village health workers (VHW) in eight districts within the two provinces. Convenience sampling was used to select the participants. This sampling was limited to communities supported by health facilities with more than 500 PLHIV enrolled into HIV care and treatment. Interviews were audio-recorded and transcripts were subjected to thematic content analysis. Results: A total of 22 community focus group discussions (FGDs) were conducted. Barriers to using HIV services cited in PLHIV and VHW FGDs were similar. These were categorised as health system-related barriers, which include user fees, long waiting times, lack of confidentiality and negative attitudes by healthcare providers, and lack of consistent community-based HIV services. Community-related barriers cited were stigma and discrimination, food insecurity, distance to facilities and counterproductive messaging from religious sectors. Client-related factors reported were inadequate male involvement in HIVrelated activities and defaulting after symptoms improved. Conclusion: Our assessment has indicated that there are several barriers to the utilisation of HIV services by PLHIV in the two provinces of Zimbabwe. As new strategies and programmes are being introduced in the current resource-constrained era, efforts should be made to understand the needs of the clients. If programmes are designed with an effort to address some of these challenges, there is a possibility that countries will quickly achieve the 90-90-90 targets set by The Joint United Nations Programme on HIV/AIDS.

Background
Sub-Saharan Africa is the world region with the greatest number of people eligible to receive antiretroviral treatment (ART). Less frequent dispensing of ART and community-based ART-delivery models are potential strategies to reduce the load on overburdened healthcare facilities and reduce the barriers for patients to access treatment. However, no large-scale trials have been conducted investigating patient outcomes or evaluating the cost-effectiveness of extended ART-dispensing intervals within community ART-delivery models. This trial will assess the clinical effectiveness, cost-effectiveness and acceptability of providing ART refills on a 3 vs. a 6-monthly basis within community ART-refill groups (CARGs) for stable patients in Zimbabwe.
Methods
In this pragmatic, three-arm, parallel, unblinded, cluster-randomized non-inferiority trial, 30 clusters (healthcare facilities and associated CARGs) are allocated using stratified randomization in a 1:1:1 ratio to either (1) ART refills supplied 3-monthly from the health facility (control arm), (2) ART refills supplied 3-monthly within CARGs, or (3) ART refills supplied 6-monthly within CARGs. A CARG consists of 6–12 stable patients who meet in the community to receive ART refills and who provide support to one another. Stable adult ART patients with a baseline viral load < 1000 copies/ml will be invited to participate (1920 participants per arm). The primary outcome is the proportion of participants alive and retained in care 12 months after enrollment. Secondary outcomes (measured at 12 and 24 months) are the proportions achieving virological suppression, average provider cost per participant, provider cost per participant retained, cost per participant retained with virological suppression, and average patient-level costs to access treatment. Qualitative research will assess the acceptability of extended ART-dispensing intervals within CARGs to both providers and patients, and indicators of potential facility-level decongestion due to the interventions will be assessed.
Discussion
Cost-effective health system models that sustain high levels of patient retention are urgently needed to accommodate the large numbers of stable ART patients in sub-Saharan Africa. This will be the first trial to evaluate extended ART-dispensing intervals within a community-based ART distribution model, and results are intended to inform national and regional policy regarding their potential benefits to both the healthcare system and patients.

Introduction
Several countries in southern Africa have made significant progress towards reaching the Joint United Nations Programme on HIV/AIDS goal of ensuring that 90% of people living with HIV are aware of their status. In Zimbabwe, progress towards this “first 90” was estimated at 73% in 2016. To reach the remaining people living with HIV who have undiagnosed infection, the Zimbabwe Ministry of Health and Child Care has been promoting index testing and partner notification services (PNS). We describe the implementation of index testing and PNS under the Zimbabwe HIV Care and Treatment (ZHCT) project and the resulting uptake, HIV positivity rate and links to HIV treatment.
Methods
The ZHCT project has been implemented since March 2016, covering a total of 12 districts in three provinces. To assess the project's performance on index testing, we extracted data on HIV testing from the district health information system (DHIS 2) from March 2016 to May 2018, validated it using service registers and calculated monthly HIV positivity rates using Microsoft Excel. Data were disaggregated by district, province, sex and service delivery point. We used SPSS to assess for statistical differences in paired monthly HIV positivity rates by sex, testing site, and province.
Results
The average HIV positivity rate rose from 10% during the first six months of implementation to more than 30% by August 2016 and was sustained above 30% through May 2018. The overall facility HIV positivity rate was 4.1% during the same period. The high HIV positivity rate was achieved for both males and females (mean monthly HIV positivity rate of 31.3% for males and 33.7% for females), with females showing significantly higher positivity compared to males (p < 0.001). The ZHCT mean monthly HIV positivity rate from index testing (32.6%) was significantly higher than that achieved through provider‐initiated testing and counselling and other facility HIV testing modalities (4.1%, p < 0.001).
Conclusions
The ZHCT project has demonstrated successes in implementing index testing and PNS by attaining a high HIV positivity rate sustained over the study period. As the country moves towards HIV epidemic control, index testing and PNS are critical strategies for targeted HIV case identification.

Pediatric COVID-19 in Lesotho and Post-pandemic Implications on Lower Respiratory Infections in Children
2024
Background The United States Agency for International Development (USAID) Reaching Impact, Saturation, and Epidemic Control (RISE) program funded Jhpiego to support the Government of Lesotho's COVID-19 response, including two national COVID-19 treatment centers. To evaluate the status of post-pandemic pediatric respiratory care in Lesotho, we analyzed pediatric treatment center data and healthcare worker (HCW) performance on pediatric COVID-19 training offered to HCWs at COVID-19 treatment centers. Methods We conducted a retrospective cohort study of patients 15 years of age or less hospitalized at two COVID-19 treatment centers in Lesotho from May 1, 2020, to April 30, 2022. Patient data were extracted from hospital files. We used the independent sample t-test, Mann-Whitney U test, or Fisher's exact test to evaluate associations between exposure variables and death. We also assessed differences between pre- and post-training examination scores of three one-day HCW training on pediatric COVID-19 using paired t-tests. Results Overall, <15-year-olds comprised 18/1,448 (1.2%) hospitalizations. Twenty-two percent (4/18) of children were hypoxemic (oxyhemoglobin saturation <94%) within the first 24 hours and 44% (8/18) at any point in the hospitalization. Oxygen utilization increased over the two-year period (p=0.004) and all eight children with hypoxemia received oxygen (p<0.001). Four of 18 (22%) patients died. For HCW training, pre- and post-training examinations were completed by 76/82 (92.7%) participants. The overall mean pretraining score was 44.6% (standard deviation (SD) 15.7%). Mean scores improved by an average of 32.2% (95% confidence interval (CI) 27.7%, 36.6%, p<0.001) on the same day post-training examination. Conclusions National COVID-19 treatment center data indicate a low burden of severe pediatric COVID-19 disease in Lesotho. However, recognized HCW knowledge gaps suggest deficiencies in identifying and referring severely ill children, which may detrimentally impact the ongoing post-pandemic care of children with severe lower respiratory infections.
