Introduction

Ebola and Marburg are severe, often fatal viral diseases that pose significant threats to global health security. Rapid detection and effective surveillance are critical components of a comprehensive strategy to prevent, control, and mitigate the impact of these and other emerging infectious diseases. With the advent of big data and artificial intelligence (AI), new opportunities have emerged for enhancing disease monitoring and outbreak prediction, making these technologies an essential component of public health preparedness. This paper explores the potential for big data analytics and AI in improving early detection, monitoring, and surveillance of Ebola and Marburg outbreaks, and includes case studies of successful implementation.


Big Data in Disease Surveillance

The proliferation of digital data sources, such as electronic health records, social media, and internet search trends, has provided public health professionals with unprecedented access to real-time information on disease transmission and spread. These large, complex datasets can be analyzed to uncover patterns, trends, and associations, enabling more accurate and timely predictions of disease outbreaks [1].


For example, HealthMap, an online platform that aggregates and visualizes data from various sources, including news reports, social media, and official reports, has been used to monitor and predict disease outbreaks, including Ebola [2]. By analyzing this diverse range of data, HealthMap provides public health officials with early warning of potential outbreaks, allowing them to respond more effectively.


Artificial Intelligence in Disease Prediction and Monitoring

AI, including machine learning and deep learning algorithms, has shown great promise in improving the accuracy and efficiency of disease prediction and monitoring. AI-driven models can analyze vast amounts of data from diverse sources, identifying patterns and relationships that may be difficult for humans to discern [3].


In the context of Ebola and Marburg, AI-driven models have been developed to predict the risk of disease spread based on factors such as climate, population density, and travel patterns. For example, a study by Bogoch et al. (2015) used machine learning algorithms to predict the international spread of Ebola during the 2014-2016 West African outbreak [4]. The model accurately predicted the countries at highest risk of importation, enabling more targeted public health interventions.


Case Studies: Successful Implementation of Big Data and AI in Disease Surveillance

The ProMED-mail System: The Program for Monitoring Emerging Diseases (ProMED) is an early warning system that utilizes big data analytics and AI to detect and track disease outbreaks. ProMED analyzes information from various sources, such as news reports, social media, and official notifications, to provide real-time updates on emerging infectious diseases, including Ebola and Marburg [5]. ProMED has been credited with identifying numerous outbreaks, including the 2003 SARS outbreak, before they were officially reported [2].


BlueDot: BlueDot is a Canadian company that uses AI-driven algorithms to predict and track the spread of infectious diseases. BlueDot’s platform analyzes large volumes of data from diverse sources, such as climate data, airline ticketing, and news reports, to predict the potential for disease outbreaks and their likely spread [6]. During the 2014-2016 Ebola outbreak, BlueDot successfully predicted the spread of the virus to Nigeria and Senegal, enabling public health officials to implement targeted interventions [7].


Challenges and Future Directions

While big data and AI hold significant promise for improving disease surveillance and outbreak prediction, there are several challenges that must be addressed. First, data quality and reliability can be an issue, particularly when utilizing non-traditional data sources such as social media. Second, integrating diverse data sources and formats can be complex and time-consuming. Finally, ensuring the privacy and security of sensitive health data is a critical concern that must be carefully managed [8].


Despite these challenges, ongoing advances in data analytics and AI technologies, as well as increased collaboration between public health professionals, data scientists, and technology companies, are expected to drive further improvements in disease surveillance and outbreak prediction. Future research should focus on refining AI-driven models, integrating diverse data sources more effectively, and addressing privacy and security concerns while maintaining the utility of big data for public health purposes.


Conclusion

Harnessing the power of big data and artificial intelligence in monitoring Ebola and Marburg outbreaks has the potential to revolutionize early detection and surveillance systems. By leveraging the vast amounts of data available from various sources and employing AI-driven models to predict and track disease spread, public health professionals can respond more effectively to potential outbreaks, ultimately saving lives and mitigating the impact of these devastating diseases.


Notes

On August 1, 2018, the Ministry of Health of the Democratic Republic of the Congo (DRC) reported an outbreak of Ebola virus disease in North Kivu Province. Cases were also reported in Ituri and South Kivu provinces. In 2019, Uganda detected and responded to four Ebola cases imported from neighboring DRC; no additional neighboring countries reported cases related to this outbreak. On June 25, 2020, the WHO declared this outbreak over.external icon In total, 3470 cases (probable and confirmed) of Ebola were reported, with 2287 deaths. This was the 10th and largest Ebola outbreak in DRC, and the second largest outbreak of Ebola ever recorded since the virus was discovered in 1976 in DRC. The confirmed cases in Uganda represent the first cases of Zaire ebolavirus in that country, and the first cases of Ebola virus disease in Uganda since 2013.
