AI is emerging as a transformative force in enhancing disease surveillance systems, as public health entities grapple with fragmented data processes.

Despite increased investments in disease surveillance following the COVID-19 pandemic, public health officials still face challenges due to disjointed systems and manual data processes. According to Steve Kearney, Global Medical Director at SAS, the lack of interoperability among various data sources impedes timely detection and response to infectious disease outbreaks. Traditional methods often rely on outdated workflows that are ill-equipped to adapt to new health threats, making it difficult to identify emerging outbreaks quickly.

Generative artificial intelligence, particularly retrieval-augmented generation (RAG), presents an opportunity to enhance the scalability and flexibility of disease surveillance. By sourcing accurate data from reliable channels, RAG can provide a comprehensive view of public health threats. However, Kearney emphasizes the importance of trustworthy AI models that incorporate robust data governance and monitoring mechanisms. This reliability is crucial for epidemiologists who depend on accurate information to inform their analyses and decisions.

Moreover, RAG can facilitate better communication among public health stakeholders by tailoring data presentations to meet specific needs. For instance, it can aggregate insights from social media, offering timely indicators of health trends that traditional surveillance systems may overlook. While RAG is not intended to replace existing surveillance methods, it serves as a valuable complement, empowering epidemiologists to detect and respond to public health challenges more effectively.

As the field evolves, the focus should shift from large language models to smaller, curated models that prioritize trust and accuracy. This approach not only enhances data interpretation but also positions health professionals to better identify and manage potential disease outbreaks.
