AbstractIntroduction: Rapid diagnostic testing has made HIV diagnosis and subsequent treatment more accessible. However, multiple factors, including improper implementation of testing strategies and clerical errors, have been reported to lead to HIV misdiagnosis. The World Health Organization has recommended HIV retesting prior to antiretroviral therapy (ART) initiation which has become pertinent with scaling up of Early Access to ART for All (EAAA). In this analysis, misdiagnosed clients are identified from a subgroup of clients enrolled in EAAA implementation study in Swaziland.Methods: The subgroup to assess misdiagnosis was identified from enrolled EAAA study clients, who had an undetectable viral load prior to ART initiation between September 1, 2014 and May 31, 2016. One hundred and five of 2533 (4%) clients had an undetectable viral load prior to initiation to ART (pre‐ART). The HIV status of clients was confirmed using the Determine HIV 1/2 and Uni‐Gold HIV 1/2 rapid tests performed serially as recommended by the national testing algorithm. The status of clients on ART was additionally confirmed by fourth‐generation HIV Ag/Ab combo tests, Architect and Genscreen Ultra.Results: Fourteen of the 105 (13%) clients were false positive (HIV negative) on confirmation testing, of whom five (36%) were still in pre‐ART care, while nine (64%) were in ART care. Overall, proportion of false positive was 0.6% (14/2533). The false‐positive clients had a median CD4 of 791 cells/ml (interquartile range (IQR): 628, 967) compared to 549 cells/ml (IQR: 387, 791) for true positives (HIV positive) (p = 0.0081) and were nearly 20 years older (p = 0.0008).Conclusions: Overall 0.6% of all enrolled EAAA clients were misdiagnosed, and 64% of misdiagnosed clients were initiated on ART. With adoption of EAAA guidelines by national governments, ART initiation regardless of immunological criteria, strengthening of proficiency testing and adoption of retesting prior to ART initiation would allow identification of misdiagnosed clients and further reduce potential of initiating misdiagnosed clients on ART.

AbstractIntroductionThe potential disruption in antiretroviral therapy (ART) services in Africa at the start of the COVID‐19 pandemic raised concern for increased morbidity and mortality among people living with HIV (PLHIV). We describe HIV treatment trends before and during the pandemic and interventions implemented to mitigate COVID‐19 impact among countries supported by the US Centers for Disease Control and Prevention (CDC) through the President's Emergency Plan for AIDS Relief (PEPFAR).MethodsWe analysed quantitative and qualitative data reported by 10,387 PEPFAR‐CDC‐supported ART sites in 19 African countries between October 2019 and March 2021. Trends in PLHIV on ART, new ART initiations and treatment interruptions were assessed. Viral load coverage (testing of eligible PLHIV) and viral suppression were calculated at select time points. Qualitative data were analysed to summarize facility‐ and community‐based interventions implemented to mitigate COVID‐19.ResultsThe total number of PLHIV on ART increased quarterly from October 2019 (n = 7,540,592) to March 2021 (n = 8,513,572). The adult population (≥15 years) on ART increased by 14.0% (7,005,959–7,983,793), while the paediatric population (<15 years) on ART declined by 2.6% (333,178–324,441). However, the number of new ART initiations dropped between March 2020 and June 2020 by 23.4% for adults and 26.1% for children, with more rapid recovery in adults than children from September 2020 onwards. Viral load coverage increased slightly from April 2020 to March 2021 (75–78%) and viral load suppression increased from October 2019 to March 2021 (91–94%) among adults and children combined. The most reported interventions included multi‐month dispensing (MMD) of ART, community service delivery expansion, and technology and virtual platforms use for client engagement and site‐level monitoring. MMD of ≥3 months increased from 52% in October 2019 to 78% of PLHIV ≥ age 15 on ART in March 2021.ConclusionsWith an overall increase in the number of people on ART, HIV programmes proved to be resilient, mitigating the impact of COVID‐19. However, the decline in the number of children on ART warrants urgent investigation and interventions to prevent further losses experienced during the COVID‐19 pandemic and future public health emergencies.
