Eastern Equine Encephalitis Differential Diagnoses

Diagnostic Considerations
The current Centers for Disease Control and Prevention (CDC) guidelines for diagnosis of an arbovirus infection require the presence of an acute febrile illness with encephalitis during a time when viral transmission is likely and at least 1 of the following criteria is met:
- Greater than 4-fold increase in the viral antibody titer between acute and convalescent sera (often 10 weeks apart)
- Isolation of the virus from CSF, blood, or tissue
- Immunoglobulin M (IgM) positive to the organism in the CSF; presumptive positives can be made from the remaining biochemical assays (eg, hemoagglutinin inhibition, immunofluorescence, neutralization, complement fixation)
