*Deaths and SMR were calculated only for cases with information about age available and in which death occurred >90 d after symptom onset. SMR was 1 when there was no increased risk. Bold indicates statistical significance. ICD-10, International Classification of Diseases, 10th Revision; NA, not applicable; SMR, standardized mortality ratio adjusted for current age, sex, and calendar year; WNND, West Nile neuroinvasive disease; WNV, West Nile virus.
