DUPAGE COUNTY IL MIR MODEL

DuPage County, Illinois

There has been evidence of mosquito infection from WNV in Illinois every year since 2001. However, locations with higher WNV mosquito infection rates (MIR) change from year to year, varying with climatic conditions. View the graph below to see the model-estimated MIR to the current week using last weeks weather data, and to next week using National Weather Service forecast data (10-day temperatures, 3-day precipitation). (updated on Monday based on data from previous weeks)

 This West Nile Virus Mosquito Infection Rate (MIR) Model provides a predicted MIR customized specifically for DuPage County, Illinois. It is a statistical model based on measurements of MIR and weather from the past ten years to find patterns. These patterns are used to estimate the level of mosquito infection for the week ahead based on the temperature and the amount of rainfall from the weeks before. Note that this model and the results are similar to the Illinois MIR model for Climate Division 2,   but again are specific to DuPage County.

 The model was developed by the University of Illinois Geographic Information Science and Spatial Epidemiology Lab (GISSA) in collaboration with the Wheaton Mosquito Abatement District, the Forest Preserve District of DuPage County, and the DuPage County Health Department. To read about the technical and scientific details, see these two papers: Shand et al. 2016 and Ruiz et al. 2010. Contact Marilyn O’Hara Ruiz(moruiz@illinois.edu) if you want more information.
