INTRODUCTION
The COVID-19 pandemic and the measures taken to limit its spread have severely disrupted health systems and medical care. People living with HIV (PLHIV) suffer from high levels of comorbidities and stigma, and often faced challenges in access to care prior to the pandemic. The aim of this study was to explore the extent to which the pandemic and the public health measures have affected medical care for PLHIV. The study took place in two different contexts in terms of care and experience of the pandemic where MSF operates, in Arua (Uganda) and Chiradzulu (Malawi).
METHODS
We conducted a multicentric mixed-methods study . The quantitative component explored patients’ retention in care and viral suppression using programmatic data routinely collected from January 2018 to April 2021 . The qualitative study investigated patient perspectives and perceptions of the impact of Covid-19 and the public health and social measures on their lives and ability to manage their health, and on HIV care. The interviews with patients were conducted from January to June 2021.
RESULTS
From 2020 to 2021, we observed a 15% decrease in active cohort among adults on any regimen and a 17% decrease among children and adolescents in Arua. During the same period in Chiradzulu, the first- and second-line cohorts decreased in size (10% drop and 12% drop, respectively). In addition, we observed a reduction in ART initiations and in clinical consultations at the start of pandemic (50% and 68% in Arua and 34% and 60% in Chiradzulu, respectively) and a gradual decrease in viral load coverage. In Uganda, the lockdown affected patients’ and caregivers’ livelihoods, education, access to food and psychosocial wellbeing negatively, which at times affected their ability to manage HIV condition at home and to adhere. Adolescents lost support, experienced increasing HIV stigma, and started to provide for themselves. In Malawi, patients and caregivers emphasized the impact of the pandemic and public health measures on livelihoods and food security and noted the reduction or absence of MSF social support activities during this time. Also, the fear of COVID at health facilities and the confusion and lack of communication about regarding day-to-day changes in activities was disturbing to both patients and staff.
CONCLUSION
The COVID-19 epidemic and public health measures had an important negative impact on HIV care in the health facilities and in the community in Arua and Chiradzulu. To ensure a conducive environment for patients’ access to essential HIV care and treatment during potential future outbreaks requires continued collaboration with the national authorities and advocacy for more non-violent and less authoritarian ways of implementing restrictions. In addition, innovative public health information campaigns about COVID-19 and care services, to reduce fear of disease and to dispel rumours and misinformation are recommended.
KEY MESSAGE
COVID-19 has severely disrupted access to health systems and treatment. The measures put in place to limit the spread of the epidemic have altered people's bearings. How has the pandemic in Arua and Chiradzulu affected PLHIV, who already suffer from higher levels of mental health problems, comorbidities and stigma?

: A multicentric, retrospective case-series analysis (facility-based) in five sites across Kenya, Malawi, Mozambique, and Uganda screened HIV-positive adults for hepatitis C virus (HCV) antibodies using Oraquick rapid testing and viral confirmation (in three sites). Results found substantially lower prevalence than previously reported for these countries compared with previous reports, suggesting that targeted integration of HCV screening in African HIV programs may be more impactful than routine screening.This is an open access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

Objective To describe how district-wide access to HIV/AIDS care was achieved and maintained in Thyolo District, Malawi. Method In mid-2003, the Ministry of Health and Médecins Sans Frontières developed a model of care for Thyolo district (population 587 455) based on decentralization of care to health centres and community sites and task shifting. Results After delegating HIV testing and counseling to lay counsellors, uptake of testing increased from 1300 tests per month in 2003 to 6500 in 2009. Shifting responsibility for antiretroviral therapy (ART) initiations to non-physician clinicians almost doubled ART enrolment, with a majority of initiations performed in peripheral health centres. By the end 2009, 23 261 people had initiated ART of whom 11 042 received ART care at health-centre level. By the end of 2007, the universal access targets were achieved, with nearly 9000 patients alive and on ART. The average annual cost for achieving these targets was €2.6 per inhabitant/year. Conclusion The Thyolo programme has demonstrated the feasibility of district-wide access to ART in a setting with limited resources for health. Expansion and decentralization of HIV/AIDS service-capacity to the primary care level, combined with task shifting, resulted in increased access to HIV services with good programme outcomes despite staff shortages.

In Thyolo District, Malawi, a study was conducted among commercial sex workers (CSWs) attending mobile clinics in order to; determine the prevalence and pattern of sexually transmitted infections (STIs), describe sexual behaviour among those who have an STI and identify risk factors associated with 'no condom use'. There were 1817 CSWs, of whom 448 (25%) had an STI. Of these, the commonest infections included 237 (53%) cases of abnormal vaginal discharge, 109 (24%) cases of pelvic inflammatory disease and 95 (21%) cases of genital ulcer disease (GUD). Eighty-seven per cent had sex while symptomatic, 17% without condoms. Having unprotected sex was associated with being married, being involved with commercial sex outside a known rest-house or bar, having a GUD, having fewer than two clients/day, alcohol intake and having had no prior medication for STI. The high levels of STIs, particularly GUDs, and unprotected sex underlines the importance of developing targeted interventions for CSWs and their clients.

Malawi offers antiretroviral treatment (ART) to all HIV-positive adults who are clinically classified as being in WHO clinical stage III or IV without 'universal' CD4 testing. This study was conducted among such adults attending a rural district hospital HIV/AIDS clinic (a) to determine the proportion who have CD4 counts >or=350 cells/microl, (b) to identify risk factors associated with such CD4 counts and (c) to assess the validity and predictive values of possible clinical markers for CD4 counts >or=350 cells/microl. A CD4 count >or=350 cells/microl was found in 36 (9%) of 401 individuals who are thus at risk of being placed prematurely on ART. A body mass index (BMI) >22 kg/m(2), the absence of an active WHO indicator disease at the time of presentation for ART, and a total lymphocyte count >1,200 cells/microl were significantly associated with such a CD4 count. The first two of these variables could serve as clinical markers for selecting subgroups of patients who should undergo CD4 testing. In a resource-limited district setting, assessing the BMI and checking for active opportunistic infections are routine clinical procedures that could be used to target CD4 measurements, thereby minimising unnecessary CD4 measurements, unnecessary (too early) treatment and costs.

OBJECTIVES
Mortality in patients starting antiretroviral therapy (ART) is higher in Malawi and Zambia than in South Africa. We examined whether different monitoring of ART (viral load [VL] in South Africa and CD4 count in Malawi and Zambia) could explain this mortality difference.
DESIGN
Mathematical modelling study based on data from ART programmes.
METHODS
We used a stochastic simulation model to study the effect of VL monitoring on mortality over 5 years. In baseline scenario A all parameters were identical between strategies except for more timely and complete detection of treatment failure with VL monitoring. Additional scenarios introduced delays in switching to second-line ART (scenario B) or higher virologic failure rates (due to worse adherence) when monitoring was based on CD4 counts only (scenario C). Results are presented as relative risks (RR) with 95% prediction intervals and percent of observed mortality difference explained.
RESULTS
RRs comparing VL with CD4 cell count monitoring were 0.94 (0.74-1.03) in scenario A, 0.94 (0.77-1.02) with delayed switching (scenario B) and 0.80 (0.44-1.07) when assuming a 3-times higher rate of failure (scenario C). The observed mortality at 3 years was 10.9% in Malawi and Zambia and 8.6% in South Africa (absolute difference 2.3%). The percentage of the mortality difference explained by VL monitoring ranged from 4% (scenario A) to 32% (scenarios B and C combined, assuming a 3-times higher failure rate). Eleven percent was explained by non-HIV related mortality.
CONCLUSIONS
VL monitoring reduces mortality moderately when assuming improved adherence and decreased failure rates.

Eighty per cent of Malawi's 8 million children live in rural areas, and there is an extensive tiered health system infrastructure from village health clinics to district hospitals which refers patients to one of the four central hospitals. The clinics and district hospitals are staffed by nurses, non-physician clinicians and recently qualified doctors. There are 16 paediatric specialists working in two of the four central hospitals which serve the urban population as well as accepting referrals from district hospitals. In order to provide expert paediatric care as close to home as possible, we describe our plan to task share within a managed clinical network and our hypothesis that this will improve paediatric care and child health.

OBJECTIVE
The evaluation of HIV treatment programs is generally based on an estimation of survival among patients receiving antiretroviral treatment (ART). In large HIV programs, loss to follow-up (LFU) rates remain high despite active patient tracing, which is likely to bias survival estimates and survival regression analyses.
METHODS
We compared uncorrected survival estimates derived from routine program data with estimates obtained by applying six correction methods that use updated outcome data by a field survey targeting LFU patients in a rural HIV program in Malawi. These methods were based on double-sampling and differed according to the weights given to survival estimates in LFU and non-LFU subpopulations. We then proposed a correction of the survival regression analysis.
RESULTS
Among 6,727 HIV-infected adults receiving ART, 9% were LFU after one year. The uncorrected survival estimates from routine data were 91% in women and 84% in men. According to increasing sophistication of the correction methods, the corrected survival estimates ranged from 89% to 85% in women and 82% to 77% in men. The estimates derived from uncorrected regression analyses were highly biased for initial tuberculosis mortality ratios (RR; 95% CI: 1.07; 0.76-1.50 vs. 2.06 to 2.28 with different correction weights), Kaposi sarcoma diagnosis (2.11; 1.61-2.76 vs. 2.64 to 3.9), and year of ART initiation (1.40; 1.17-1.66 vs. 1.29 to 1.34).
CONCLUSIONS
In HIV programs with high LFU rates, the use of correction methods based on non-exhaustive double-sampling data are necessary to minimise the bias in survival estimates and survival regressions.
