A Multiplex Microsphere Immunoassay for Zika Virus Diagnosis.

ABSTRACT: Rapid and accurate diagnosis of infectious agents is essential for patient care, disease control, and countermeasure development. The present serologic diagnosis of Zika virus (ZIKV) infection relies mainly on IgM-capture ELISA which is confounded with the flaw of cross-reactivity among different flaviviruses. In this communication, we report a multiplex microsphere immunoassay (MIA) that captures the diagnostic power of viral envelope protein (that elicits robust, yet cross-reactive antibodies to other flaviviruses) and the differential power of viral nonstructural proteins NS1 and NS5 (that induce more virus-type specific antibodies). Using 153 patient specimens with known ZIKV and/or dengue virus (DENV; a closely related flavivirus) infections, we showed that (i) ZIKV envelope-based MIA
