Steps in Outbreak Investigation

Steps in Outbreak Investigation

In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:

Area of Science:

Epidemiology
Machine Learning
Time Series Analysis

Background:

Traditional single time series models have limitations in accurately predicting infectious disease incidence.
Combining diverse models using a stacking architecture can capture complex data patterns more effectively.
This study addresses the need for improved prediction models in infectious disease surveillance.

Purpose of the Study:

To compare the predictive performance of traditional time series models and deep learning algorithms for malaria case prediction.
To explore the application and value of stacking methods in infectious disease prediction.
To develop a novel ensemble model for enhanced malaria incidence forecasting.

Main Methods:

Applied Autoregressive Integrated Moving Average (ARIMA), Seasonal-Trend decomposition using Loess (STL)+ARIMA, Backpropagation Artificial Neural Network (BP-ANN), and Long Short-Term Memory (LSTM) network models.
Utilized malaria and meteorological data from Yunnan Province (2011-2017) for model simulations.
Employed Gradient-Boosting Regression Trees (GBRTs) to create a stacking ensemble model, evaluating performance using Root Mean Square Error (RMSE), Mean Absolute Scaled Error (MASE), and Mean Absolute Deviation (MAD).

Main Results:

Individual models showed varying performance: LSTM achieved the lowest RMSE (7.208), MASE (0.266), and MAD (5.691).
The stacking ensemble model significantly outperformed individual models, reducing RMSE to 6.810, MASE to 0.224, and MAD to 4.625.
The ensemble model demonstrated superior predictive accuracy compared to all four sub-models.

Conclusions:

A novel ensemble model utilizing stacking architecture enhances the accuracy of malaria case prediction.
The developed stacking model demonstrates superior performance over individual traditional and deep learning models.
Stacking architecture holds significant potential for improving infectious disease prediction and surveillance.
