Background:
- Malaria prevention strategies require reliable forecasting models.
- Meteorological factors significantly influence malaria transmission dynamics.
Purpose of the Study:
- To develop and evaluate a meteorological factors-based predictive model for malaria forecasting.
- To provide reliable data for developing malaria prevention strategies.
Main Methods:
- Collected malaria occurrence and climate data (1994-1999) from Yunnan province.
- Utilized Neural Network Toolbox in Matlab 6.1 to establish a forecasting model.
- Included meteorological factors: pressure, temperature, humidity, rainfall, sunshine hours, etc.
Main Results:
