Recent studies examine behaviourally informed messaging to increase HIV testing, voluntary medical male circumcision, and return to HIV care through digital platforms and text messaging. Randomised and quasi-experimental designs feature prominently, reflecting strong methodological expertise. Findings highlight both the promise and limits of nudges, emphasizing the importance of visibility, context, and follow-through in converting interest into sustained engagement.

Qualitative and mixed-methods research further explores adolescent sexual decision-making, TB stigma, preventive therapy for child contacts, and digital adherence technologies. This body of work underscores patient-centred care, caregiver communication, and stigma reduction as central to improving outcomes. Collectively, these contributions inform scalable, evidence-based interventions across South Africa’s HIV and TB response.
