The data on avian and mosquito infections were converted into surveillance variables using empirical Bayes methodology. A preliminary logistic regression model was formulated to relate these surveillance variables and demographic variables to case fatality rates. The statistical technique of backward elimination was applied to obtain a final model in terms of the variables most useful for predicting case outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results.<\/jats:title>\n                    <jats:p>The probability of a fatal outcome depends on the poverty rate for the county in which the infected person lives ( p=0.0283), the average temperature ( p&lt;0.0001), and surveillance variables reflecting the fractions of Culex pipiens and Culex restuans mosquitoes among infected mosquitoes ( p=0.0079; p=0.0076).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions.<\/jats:title>\n                    <jats:p>Effective WNV educational programs and control measures are vital, especially in poverty-stricken areas.
