Accurate infectious disease forecasting is possible even without routine surveillance. Optimizing data from existing sites improves predictions, and monitoring population centers can serve as a reliable proxy for effective disease surveillance.
Area of Science:
- Epidemiology
- Network Science
- Public Health
Background:
- Sentinel observations are crucial for infectious disease surveillance, but many regions lack adequate capacity.
- Existing surveillance systems often struggle with accurate forecasting and estimation, especially in data-scarce areas.
Purpose of the Study:
- To develop and validate a framework for optimizing surveillance site selection to improve infectious disease forecasting.
- To assess the feasibility of using collective data from multiple sites for accurate disease estimation and prediction in unmonitored locations.
Main Methods:
- Developed a framework to optimize surveillance site selection by minimizing uncertainty propagation in a networked disease transmission model.
- Utilized influenza outbreak data from 35 US states to compare the optimized system with alternative designs based on population and mobility.
- Validated a proxy method using regional population centers with model simulations for 3,108 US counties and historical data for human metapneumovirus and seasonal coronavirus.
Main Results:
- The optimized surveillance system generated superior near-term predictions for influenza compared to systems based on population and human mobility.
- Monitoring regional population centers proved to be a reasonable proxy for the optimized network, enhancing surveillance capabilities.
- The proxy method demonstrated effectiveness for guiding the systemic allocation of surveillance efforts for various respiratory pathogens.
Conclusions:
- Collective data utilization and optimized site selection can enable accurate infectious disease forecasting in locations with limited surveillance capacity.
- A proxy method based on monitoring regional population centers offers a practical approach to guide surveillance efforts for diseases with scarce historical data.
- The proposed framework enhances the efficiency and effectiveness of public health surveillance systems for infectious diseases.
