Key Messages:
Multiple detections of West Nile Virus (WNV)-positive mosquitoes in Orange County and a much higher-than-usual number of human WNV cases in California to date signal that this WNV season is starting earlier and may be more intense than usual.
California Department of Health (CDPH) is offering a new WNV diagnostic test with improved sensitivity and specificity for WNV through their Viral and Rickettsial Disease Laboratory (VRDL).
The new assay requires whole blood, a specimen type not required for WNV testing in the past.
