Participants were eligible if they were assigned female sex at birth, aged 18-25 years, not living with HIV, sexually active, newly initiating PrEP, had regular access to a mobile telephone, and could read. Using sequentially numbered, sealed, opaque envelopes containing group allocation, a staff member assigned enrolled participants (1:1) to receive one of two adherence-support interventions: once per week two-way SMS communication or participation in a WhatsApp peer-support group. Participants assigned to WhatsApp were put into groups with approximately 25 participants, during which they were prompted by staff facilitators to discuss any challenges with PrEP use or other events happening in their lives. The allocation sequence was generated by the data manager using random numbers with variable block sizes between 10 and 14. Only trial investigators were masked to participant intervention assignments; participants, people giving interventions, people assessing outcomes, and people analysing data were not masked to group assignment. All enrolled participants were offered PrEP (ie, co-formulated, once per day oral emtricitabine 200 mg and tenofovir disoproxil fumarate 300 mg). The primary outcome was high PrEP adherence at month 9, defined as concentration of tenofovir diphosphate on dried blood sample of 700 fmol per punch or more. At month 3, participants with low PrEP adherence were randomly assigned to a secondary, intensified intervention of issue-focused counselling once per month or drug-level feedback counselling based on PrEP drug concentrations at months 3 and 6. The protocol was registered at ClinicalTrials.gov (NCT04038060) and the trial is complete.</p><p><strong>Findings: </strong>Participants were enrolled and followed up between May 16, 2019, and Jan 25, 2022.

At month 9, 34 (20%) of 174 participants in the two-way SMS arm had tenofovir diphosphate 700 fmol per punch or more, compared with 32 (18%) of 174 in the WhatsApp arm (relative risk 1·06, 95% CI 0·69-1·64; p=0·78).

Therefore, there is a crucial need to evaluate current epidemiological trends and monitor global progress towards HIV incidence and mortality reduction goals. In this analysis, we assess the current burden of HIV in 204 countries and territories and forecast HIV incidence, prevalence, and mortality up to 2050 to allow countries to plan for a sustained response with an increasing number of people living with HIV globally.</p><p><strong>Methods: </strong>We used the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 analytical framework to compute age-sex-specific HIV mortality, incidence, and prevalence estimates for 204 countries and territories (1990-2021). We aimed to analyse all available data sources, including data on the provision of HIV programmes reported to UNAIDS, published literature on mortality among people on antiretroviral therapy (ART) identified by a systematic review, household surveys, sentinel surveillance antenatal care clinic data, vital registration data, and country-level case report data. We calibrated a mechanistic simulation of HIV infection and natural history to available data to estimate HIV burden from 1990 to 2021 and generated forecasts to 2050 through projection of all simulation inputs into the future. Historical outcomes (1990-2021) were simulated at the 1000-draw level to support propagation of uncertainty and reporting of uncertainty intervals (UIs). Our approach to forecasting utilised the transmission rate as the basis for projection, along with new rate-of-change projections of ART coverage. Additionally, we introduced two new metrics to our reporting: prevalence of unsuppressed viraemia (PUV), which represents the proportion of the population without a suppressed level of HIV (viral load <1000 copies per mL), and period lifetime probability of HIV acquisition, which quantifies the hypothetical probability of acquiring HIV for a synthetic cohort, a simulated population that is aged from birth to death through the set of age-specific incidence rates of a given time period.</p><p><strong>Findings: </strong>Global new HIV infections decreased by 21·9% (95% UI 13·1-28·8) between 2010 and 2021, from 2·11 million (2·02-2·25) in 2010 to 1·65 million (1·48-1·82) in 2021. HIV-related deaths decreased by 39·7% (33·7-44·5), from 1·19 million (1·07-1·37) in 2010 to 718 000 (669 000-785 000) in 2021. The largest declines in both HIV incidence and mortality were in sub-Saharan Africa and south Asia. However, super-regions including central Europe, eastern Europe, and central Asia, and north Africa and the Middle East experienced increasing HIV incidence and mortality rates.
