EVALUATION FOR ARBOVIRAL INFECTION AMONG CHILDREN HOSPITALIZED IN COLORADO WITH ASEPTIC MENINGITIS AND ENCEPHALITIS.

Among 39 children hospitalized in Colorado with aseptic meningitis or encephalitis, 16 (41%) had an etiology identified, including 2 (5%) with West Nile virus infection. Despite extensive testing, no other arboviral infections were identified. Arboviral infection should be considered in children with neuroinvasive disease during arboviral season with testing directed toward viruses endemic to the region and type of exposure.
