Nineteen (79%) of the 24 cases for which such data were available occurred in males; the median age of patients was 45 years (range: 17--80 years). Date of illness onset ranged from May 14 to June 30; one case was fatal.

Seven presumptive West Nile viremic blood donors (PVDs) have been reported to ArboNET in 2005. Of these, five were reported in Texas, and two in Arizona.

In addition, 281 dead corvids and 96 other dead birds with WNV infection have been reported from 16 states during 2005. WNV infections have been reported in horses in 11 states.
