Evaluation of Commercially Available Serologic Diagnostic Tests for Chikungunya Virus

Chikungunya virus (CHIKV) is present or emerging in dengue virus endemic areas. Infections caused by these viruses share some common signs/symptoms, but prognosis, patient care, and persistent symptoms differ. Thus, accurate diagnostic methods are essential for differentiating the infections. We evaluated 4 CHIKV serologic diagnostic tests, 2 of which showed poor sensitivity and specificity.
