Introduction

The artificial intelligence (AI) era is rapidly reshaping numerous sectors including, education, agriculture, healthcare, and medicine. The application of deep learning algorithms, in AI is significantly enhancing the efficiency, diagnosis, and speed of treatment.^1,2 The high-income countries (HICs) and upper middle-income countries (UMICs) are adopting and making investments in further unleashing and optimizing the application of AI in several sectors such as wearable devices, telemedicine, precision medicine, genetic-based solutions, and drug discovery and development; all of which are aimed at building a robust approach to patient care worldwide. The World Health Organization's (WHO), Global Strategy on Digital Health recommended cross-country collaboration, to ensure equity, access, and affordability of improved medical care services and universal health coverage with a target year of between 2020 and 2025. ³

However, despite all of the promising potential and impact, as demonstrated and continued to evolve in most of the HICs and UMICs, AI has yet to unleash its full potential in Africa's healthcare space. Many of the concerns are associated with algorithmic bias, health data poverty, and foreign dominations (digital colonization).^4,5 Also, the lack of proper use of human resources, bureaucratic administrative processing, extensive urban–rural divide, inequity in access to healthcare, and challenges of policy implementation by the government may be associated with difficulty in having a coordinated solution to addressing emerging problems in Africa's digital health.^6–8 Furthermore, the African population continues to grow with the youth accounting for the majority which presents both challenges and opportunities. If the political leadership harnesses the potential of the population and implements effective policies, technological startups can be used to tackle local health issues thereby improving healthcare across the continent. ⁹ Therefore, AI tools can be tailored to enhance governmental functions, at the same time ensuring an intersection of ethics, privacy, automation, bias, and transparency of AI tools in optimizing health outcomes in Africa. In this commentary, we aim to evaluate current and potential roles in which AI can be applied in the African health sector, identify opportunities, and address challenges impeding its implementation through tailored interventions and an AI framework to simulate effective policy development.
