Non-occupational post-exposure prophylaxis (nPEP) and pre-exposure prophylaxis (PrEP) are effective HIV prevention methods, but their use is low in Sub-Saharan Africa (SSA). Mobile applications (apps) could increase uptake and adherence to these interventions, yet research on their use in communities is limited. Furthermore, there is limited information on the design and development of these apps, impacting their implementation. This scoping review aims to identify, analyse and evaluate mobile apps designed to improve nPEP uptake, adherence and linkage to PrEP services focusing on key features, barriers and facilitators. It also seeks to address gaps in studies assessing the feasibility, usability and acceptability of these apps, with the goal of informing future research, healthcare policies and public health strategies to reduce the HIV burden in Sub-Saharan Africa.

This review will follow the Arksey and O'Malley framework and search databases such as PubMed, Scopus and Web of Science for relevant studies. Two independent reviewers will screen and assess full-text studies. Primarily, the review will include studies on digital interventions for nPEP and PrEP, excluding opinion papers, narrative reviews and sub-studies. Grey literature from sources like Google Scholar will also be considered. Data will be captured using a charting form, and results will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews framework. Completion is expected in December 2025.

No ethical approval is required as publicly available materials will be used. Results will be shared through peer-reviewed journals, conferences and with policymakers to inform HIV prevention strategies.

Effective community-based disease management is essential for public health. In low- and middle-income countries, sustainable strategies for timely diagnosis and treatment are a research priority. This study aims to assess the feasibility of a non-invasive saliva self-sampling method, paired with digitally linked molecular point-of-care diagnostics, for detecting respiratory infections among paediatric patients in the Tshwane District, South Africa.

A field study will be conducted at Steve Biko Academic Hospital to compare saliva collection using the CandyCollect lollipop device and standard mouth swabs. The spiral groove of the lollipop device captures pathogens, which are stored in DNA/RNA preservation media and later analysed using quantitative PCR and commercially available rapid antigen tests. The multiplex respiratory pathogen panel, based on TaqMan real-time PCR technology, targets key paediatric pathogens including Streptococcus pneumoniae, Haemophilus influenzae, Mycoplasma pneumoniae, respiratory syncytial virus (RSV) and influenza A/B. Nucleic acids will be extracted using standard viral extraction kits and analysed following manufacturer protocols. Internal controls will be included in each qPCR run, and samples with CT values below defined thresholds will be considered positive. Rapid antigen tests will detect common pathogens such as influenza A/B, RSV and SARS-CoV-2 for comparative analysis. User experience and acceptability will be assessed via child-friendly and caregiver surveys following sample collection. The study will be implemented in two phases: diagnostic performance evaluation and user feedback assessment. The protocol is aligned with the Standard Protocol Items: Recommendations for Interventional Trials 2013 checklist.

Ethical approval has been granted by the University of Pretoria (509/2023) and the Gauteng Department of Health (GP_202406_032). The study is registered in the Pan African Clinical Trial Registry (PACTR202411743094783). Findings will be disseminated through peer-reviewed journals, conferences and stakeholder briefings. The study complies with South Africa’s Protection of Personal Information Act. Data collection is scheduled from November 2024 to February 2025, with project completion expected within 1 year.
