Introduction

Technology has revolutionized disease surveillance in Africa, transforming how health data is collected, analysed, and disseminated. Electronic reporting platforms, digital surveillance tools, and mobile technologies have significantly enhanced the timeliness and accuracy of disease surveillance, enabling quicker responses to outbreaks. This article explores the role of technology in modernizing disease surveillance and its impact on public health in Africa.

Electronic Reporting Platforms

Sierra Leone has been a trailblazer in implementing electronic disease surveillance systems, with a significant shift from the traditional paper-based reporting methods to a more advanced, web-based platform. This transition has been facilitated through the integration of the e-IDSR (electronic Integrated Disease Surveillance and Response) system with the District Health Information System. The e-IDSR system allows health workers to collect, enter, and transmit data from remote areas directly to central databases in real-time, reducing delays associated with manual data collection and reporting. The integration with DHIS2 also enhances the accuracy of disease reporting, as the system includes built-in validation tools that help identify discrepancies or errors during data entry. Furthermore, this shift to electronic systems has facilitated the integration of various disease surveillance data, such as data on malaria, cholera, and Ebola, into a centralized system that can be accessed by health officials and other stakeholders quickly. DHIS2 is a widely recognized platform used globally for managing health data and supporting decision-making in public health. By incorporating DHIS2 into the e-IDSR system, Sierra Leone has streamlined its disease surveillance processes, ensuring more timely, accurate, and comprehensive data collection.

Digital Surveillance Tools

Africa CDC is developing digital surveillance indicators and online dashboards using social media and internet data to monitor infectious diseases like cholera and Ebola. This approach aims to strengthen real-time surveillance and guide interventions. The Surveillance, Outbreak Response Management and Analysis System (SORMAS) is a comprehensive digital platform used in Nigeria and Ghana to manage disease surveillance and outbreak responses. It provides real-time data critical for tackling deadly disease outbreaks.

Mobile Technologies

Mobile (mHealth) apps are increasingly used for reporting health data and tracking disease outbreaks. These tools enable health workers to submit reports quickly and access critical information on the go. Mobile technologies also facilitate community engagement in health surveillance by disseminating health information and promoting preventive behaviours.

Future Directions

The future of disease surveillance in Africa lies in scaling up existing digital systems and expanding their reach to cover more regions, particularly in low-resource settings where infrastructure and technological capabilities are limited. While several countries have successfully implemented digital disease surveillance systems, the challenge remains to extend these platforms to rural and underserved areas, where health data collection and reporting are often less reliable. Scaling up digital surveillance requires a multi-faceted approach, which includes not only expanding the technical infrastructure—such as internet connectivity, mobile networks, and reliable power sources—but also building the necessary human resources to manage and operate these systems effectively. This scaling-up effort will focus on integrating new technologies such as artificial intelligence (AI), machine learning, and big data analytics, which can enhance disease prediction models, automate data processing, and improve the accuracy of health forecasting. For instance, AI algorithms can analyse vast amounts of health data to predict disease outbreaks before they occur, enabling pre-emptive action to prevent widespread transmission. Additionally, mobile health technologies (mHealth), including apps for data collection, real-time reporting, and community-based health monitoring, will continue to be integral in bridging gaps in disease surveillance across the continent.

International Collaboration

International collaboration is a cornerstone for advancing disease surveillance systems in Africa. Effective disease surveillance is not only a national responsibility but also a regional and global one. Partnerships between African countries and international health organizations, such as the World Health Organization (WHO), Africa Centres for Disease Control and Prevention (Africa CDC), and Global Fund, are all essential in sharing the best practices, resources, and expertise to strengthen digital surveillance systems across the continent. The future direction of disease surveillance in Africa hinges on the scaling up of digital systems to cover all regions, especially underserved and rural areas, while simultaneously strengthening international collaborations. 

Conclusion

Technology has transformed disease surveillance in Africa, offering unprecedented opportunities for timely and effective public health responses. By leveraging electronic reporting platforms, digital surveillance tools, and mobile technologies, Africa can strengthen its health systems and improve outcomes in the face of emerging health challenges.
