Protecting HIV service delivery for key populations in southern Africa in the context of the COVID-19 pandemic.

The 2025 UNAIDS targets prioritize reaching all subpopulations living with HIV and those at risk for HIV as the only pathway to achieving control of the HIV epidemic. This has brought to the fore the importance of addressing the needs of key marginalized groups and placing such communities at the center of HIV response strategies. However, the COVID-19 pandemic has resulted in a setback in terms of confronting HIV. With this in mind, it is important not only to protect services within HIV responses among key populations, but also to expand such services to meet the UNAIDS 2025 targets. Without this, gains in controlling COVID-19 may be achieved at the expense of losses in controlling the spread of HIV, which had been achieved after sustained and resource-intensive actions.

Impact of early antiretroviral treatment on sexual behaviour: a randomised comparison.

BACKGROUND: Antiretroviral treatment (ART) reduces HIV infectiousness but the effect of early ART on sexual behaviour is unclear. METHODS: We assessed, within the START randomized trial that enrolled HIV-positive adults with CD4 cell count greater than 500 cells/µl, the effect of early (immediate) versus deferred ART on: condomless sex with HIV-serodifferent partners (CLS-D); all condomless sex (CLS); HIV transmission-risk sex (CLS-D-HIV risk, defined as CLS-D and: not on ART or started ART <6 months ago or viral load greater than 200 copies/ml or no viral load in past 6 months), during 2-year follow-up. Month-12 CLS-D (2010-2014) was the primary outcome. RESULTS: Among 2562 MSM, there was no difference between immediate and deferred arms in CLS-D at month 12 [12.6 versus 13.1%; difference (95% CI): -0.4% (-3.1 to 2.2%), P = 0.75] or month 24, or in CLS. Among 2010 heterosexual men and women, CLS-D at month 12 tended to be higher in the immediate versus deferred arm [10.8 versus 8.3%; difference:2.5% (-0.1 to 5.2%), P = 0.062]; the difference was greater at month 24 [9.3 versus 5.6%; difference: 3.7% (1.0 to 6.4%), P = 0.007], at which time CLS was higher in the immediate arm (20.7 versus 15.7%, P = 0.013). CLS-D-HIV risk at month 12 was substantially lower in the immediate versus deferred arm for MSM [0.2 versus 11%; difference: -10.7% (-12.5 to -8.9%), P < 0.001] and heterosexuals [0.6% versus 7.7%; difference: -7.0% (-8.8 to -5.3%), P < 0.001], because of viral suppression on ART. CONCLUSION: A strategy of early ART had no effect on condomless sex with HIV-serodifferent partners among MSM, but resulted in modestly higher prevalence among heterosexuals. However, among MSM and heterosexuals, early ART resulted in a substantial reduction in HIV-transmission-risk sex, to a very low absolute level.

Advanced disease at enrollment in HIV care in four sub-Saharan African countries: change from 2006 to 2011 and multilevel predictors in 2011.

OBJECTIVES: To examine changes between 2006 and 2011 in the proportion of HIV-positive patients newly enrolled in HIV care with advanced disease and the median CD4 cell count at enrollment; and identify patient, facility, and contextual-level factors associated with late enrollment in care in 2011. DESIGN: Cross-sectional over time. METHODS: For time-trends analyses, routinely collected patient-level data (307 110 adults newly enrolled in 138 HIV clinical care facilities) in Kenya, Mozambique, Rwanda and Tanzania; and for analyses of correlates, patient-level data (46 201 in 195 facilities), and facility and population-level survey data were used. Late enrollment was defined as CD4 cell count 350 cells/µl or less and/or WHO clinical stage 3/4. RESULTS: Late enrollment declined from 69.9 to 57.2% (P < 0.0001); median CD4 cell count increased from 242 to 292 cells/µl (Ptrend < 0.0001). In 2011, risk of late enrollment was significantly higher for men and nonpregnant women vs. pregnant women; patients aged above 25 vs. 15-25 years; nonmarried vs. married; and those entering from sites other than prevention of mother-to-child transmission. More extensive HIV testing coverage in the region of a facility was significantly associated with lower risk of late enrollment. CONCLUSIONS: Despite improvement, in 2011, 57% of patients entered HIV care who were already antiretroviral therapy-eligible. The lower risk of late enrollment among those referred from prevention of mother-to-child transmission and in regions where HIV testing coverage was higher suggests that innovative approaches to rapidly increase testing uptake among people living with HIV prior to the development of symptoms have the potential to reduce late enrollment in care.
