Bridging the Distance: A Survey of the African Diaspora's Role in Health System Strengthening in Comoros via Digital Platforms (2021–2026)

This survey research investigates the role of African diaspora health professionals in strengthening health systems in the Comoros via digital platforms from 2021 to 2026. It addresses critical human resource shortages and limited specialist expertise within the Comorian healthcare sector. Using a structured online survey, data were collected from 150 diaspora health professionals of Comorian origin and 85 in-country healthcare workers to evaluate the prevalence, nature, and perceived efficacy of digital contributions. Quantitative and qualitative analyses reveal a significant increase in virtual mentorship and telemedicine consultations since 2021, particularly in paediatrics, cardiology, and public health. Respondents reported that these interventions enhanced clinical knowledge, influenced patient management protocols, and strengthened professional networks. However, the study identifies persistent barriers, including inconsistent internet connectivity, variable digital literacy, and a lack of formalised integration within national health systems. The research concludes that the diaspora represents a vital, underutilised asset for health system strengthening. It advocates for structured, institutionally led digital health partnerships to harness this expertise sustainably. This work underscores the potential of south-south digital collaboration in advancing health equity and building resilient health systems across Africa.
