Abstract
The clinical features associated with West Nile virus (WNV) infections are described based on data collected from history forms submitted with samples during a province-wide WNV testing programme. Age 40–59 years (OR 1.7, p<0.008), residence in the southeast of Alberta (OR 4.2, p<0.001), maculopapular rash (OR 8.6, p<0.001) or tremor (OR 3.6, p<0.001) were independently associated with WNV infection.
