Malaria Historical Analysis

Climate variables may effect malaria transmission in certain regions. These products aid to determine the historical risk for malaria due to climatic factors.

The maps and charts in this section may aid in forecasting malaria epidemics by helping the user understand the climate risk of their region by:

Studies show that three climatic variables are related to malaria outbreaks. These variables and the range that may increase the risk for malaria transmission are listed below.

Seasonal Climatic Suitability for Malaria Transmission
This map shows the number of months suitable for malaria transmission, based on climatological averages. Suitability is defined as the coincidence of precipitation accumulation greater than 80 mm, mean temperature between 18°C and 32°C, and relative humidity greater than 60%.
Rwanda Administrative-Average WASP Index
This plot shows the time series of 12-month Weighted Anomaly Standardization Precipitation (WASP) index relative to a baseline period. The purpose of this tool is to provide a simple visual means of relating averaged precipitation to a reference period of interest.
