West Nile virus (WNV) is one of the leading causes of arboviral encephalitis in the United States but is often underdiagnosed. Despite the wide breadth of WNV-induced clinical disease syndromes, many of the symptoms associated with WNV are nonspecific at the time of presentation; thus, choosing the right diagnostic tool is essential to not only understand the true burden of disease but also provide pathogen-directed interventions for WNV-infected patients. In this chapter, we briefly discuss the three most common types of diagnostic methods for WNV in human clinical samples: nucleic acid detection, enzyme-linked immunoassay (ELISA), and plaque reduction neutralization test (PRNT) and present the method for PRNT.
