Clinical manifestations, diagnosis, and treatment of West Nile virus infection

Data from the 2002 outbreak in the United States suggested that rash appears in approximately one-half the patients with WN fever [2], which may be more frequent than with neuroinvasive disease [3]. The rash is typically maculopapular, involves the chest, back and arms, and generally lasts for less than one week (show picture 1). The rash is sometimes accompanied by complaints of dysesthesia and pruritis [4]. Generalized lymphadenopathy, although commonly reported in previous outbreaks, is rare in contemporary outbreaks.
