Opportunities and risks of big data in disease surveillance.
summary
Panel argues big data can shorten detection by days but often fails to give earlier warning in practice; examples include global pandemic models built from NASA/IATA mobility + stochastic SIR models (2009 H1N1 sometimes predicts arrival week), hospital proximity sensors that map contact networks for nosocomial outbreak control, and mining web searches/Wikipedia or HealthMap with machine learning/NLP. Airtel handing over mobile phone traces in Senegal enables rapid contact tracing; participatory platform reaches 50,000 volunteers. Major risks: reidentification, legal limits (GDPR tensions) and unresolved governance.
