RESEARCH: ILLINOIS WNV MOSQUITO INFECTION RATE MODEL
ILLINOIS MIR PREDICTION MODEL - CLIMATE DIVISION 5
Plots below: Top: Measureand and estimated mosquito infection rate (MIR) for 2017, measured MIR for 2012, and the 2005-2013 average MIR by Climate Division. Week 18 corresponds approximately to the first week of May, Week 30 to the last week of July and Week 40 to the first week of October. Lines can be turned off and on, scales can be expanded, and actual values can be viewed using a mouse. Bottom: Historical (2004-2013) plots of measured MIR and number of human cases per Week.
Years following warm and dry winters as well as hot dry summers are most conducive to high numbers of human WNV cases and high values of MIR. Few cases of WNV are found during wet summers that are either cool or hot. Cool, but dry conditions often result in a late start to the WNV season.
