Fig. 1. : agarose gel electrophoresis of reverse transcription-polymerase chain reaction assays for Zika virus (ZIKV) detection. The arrow indicates the 364 bp amplicon expected for ZIKV. RNA extracted from serum samples of patients in acute-phase of dengue fever and Chikungunya fever and a negative serum sample were included as negative controls. CHIKV: Chikungunya virus; M: molecular size marker; 1-21: serum samples.
