Summary
Optimizing infectious disease detection requires smart spatial sampling. This study uses human mobility data to improve testing efficiency, reducing screened individuals while maintaining high accuracy in identifying infections.
Area of Science:
- Epidemiology
- Public Health
- Data Science
Background:
- Effective outbreak management relies on timely and precise detection of emerging infections.
- Human mobility patterns are critical drivers of infectious disease spatial transmission dynamics.
- Spatial sampling strategies can optimize testing resource allocation for infection detection.
Purpose of the Study:
- To introduce a spatial sampling framework using human mobility data to optimize testing resource allocation for emerging infections.
- To enhance the precision of infection detection by integrating individual movement and contact behavior.
- To develop a cost-effective solution for containing infectious diseases through optimized testing deployment.
Main Methods:
- Integrated mobility patterns, derived from point-of-interest and travel data, into four community-level spatial sampling approaches.
- Developed Case Flow Intensity (CFI) and Case Transmission Intensity (CTI) metrics informed by spatiotemporal analysis of human mobility.
- Evaluated mobility-based spatial sampling using actual and simulated outbreaks under various transmissibility, intervention, and population density scenarios.
Main Results:
- Mobility-informed spatial sampling, specifically CFI and CTI, significantly enhances community-level testing efficiency.
- Reduced the number of individuals screened while maintaining high accuracy in infection identification.
- Demonstrated the crucial role of prompt CFI and CTI application in densely populated areas for highly contagious infections.
Conclusions:
- Leveraging inter-community movement data and initial case locations optimizes spatial sampling for infectious disease detection.
- The proposed framework extends spatiotemporal mobility data analysis into spatial sampling for effective disease surveillance.
- This approach offers a cost-effective strategy for optimizing testing resource deployment to contain emerging infectious diseases.
