Area of Science:

Epidemiology
Mathematical Biology
Computational Science

Background:

Mathematical models are crucial for understanding disease outbreaks but often lack accuracy due to oversimplification.
Model predictions can conflict with real-world data, necessitating model improvement for reliable public health decisions.

Purpose of the Study:

To address the inconsistency between simplified epidemiological models and real-world data.
To propose a novel method for enhancing the accuracy of mathematical models in epidemiology.
To demonstrate the method's effectiveness using the 2016 Zika outbreak in Brazil.

Main Methods:

Development of an embedded discrepancy operator, a modification to existing model equations.
Calibration of the modified model using all available relevant data.
Case study application to the 2016 Zika outbreak in Brazil.

Main Results:

The enriched model demonstrated significantly improved consistency with real-world data compared to standard models.
The embedded discrepancy operator effectively reconciles model output with observed epidemiological trends.
The proposed method proved generalizable to other mathematical models in epidemiology.

Conclusions:

The embedded discrepancy operator offers a practical approach to enhance the accuracy of epidemiological models.
This method improves the reliability of predictions for disease outbreaks, aiding public health strategies.
The approach is adaptable and broadly applicable across various epidemiological modeling scenarios.
