Development of a novel NS1 competitive enzyme-linked immunosorbent assay for the early detection of Zika virus infection.

Zika virus (ZIKV) is a flavivirus that has emerged as a global health threat after the 2015 outbreak in the Americas, where devastating congenital defects were documented. There are currently no vaccines to prevent ZIKV infections nor commercially available clinical diagnostic tests demonstrated to...
