Processing dynamic contact data for disease transmission models significantly impacts network topology and disease spread. Careful consideration of data processing decisions is crucial for accurate modeling and policy implications.
Area of Science:
- Epidemiology
- Network Science
- Computational Biology
Background:
- Dynamic contact data is vital for understanding infectious disease transmission.
- Processing contact data can alter network structure and disease simulation outcomes.
Purpose of the Study:
- To investigate how four data processing decisions influence contact data information content and disease transmission models.
- To identify which processing decisions have the most significant impact on model dynamics.
Main Methods:
- Examined the effects of temporal sampling window (TSW), spatial threshold (SpTh), minimum contact duration (MCD), and temporal aggregation.
- Assessed changes in information content via entropy and evaluated impacts on disease transmission model metrics (R0, time to peak infection, epidemic extent).
Main Results:
- Processing decisions significantly altered disease transmission dynamics.
- Spatial threshold (SpTh) had the largest independent effect on information content.
- Model metrics like R0 and time to peak infection were more sensitive to information changes than epidemic extent.
Conclusions:
- Data processing choices alone can substantially influence insights from dynamic contact data in transmission modeling.
- Careful consideration of processing decisions is essential before using contact-based models for analysis, comparison, or policy formulation.
