Rapid detection of the virus in field-collected specimens can accelerate appropriate mosquito control measures that could prevent transmission and disease among human population. In this study we developed a rapid, sensitive and specific real time PCR for the detection of ZIKV circulating in Africa and Asia. This assay will be a useful tool for differential Zika fever diagnostics in a situation where number of other disease like malaria, dengue, chikungunya co-circulate and are clinically indistinguishable.

After 7 days of propagation, viral infection was tested by an indirect immunofluorescence assay (IFA) using specific hyperimmune mouse ascitic fluids as previously described [17] and supernatants from infected cells were collected as stocks for virus RNA isolation. ZIKV stocks were used for sequencing and evaluation of the sensitivity of the rRT-PCR assay. Other flaviviruses were used to evaluate the specificity of the assay.

Alignment of the designed primers and probe with Zika virus strain sequences. Dots indicate identity with the consensus sequence on the top of the alignment. Sensitivity and specificity of the rRT-PCR assay
The assay detected the RNA of all 37 ZIKV strains (Table 1) . The detection limit of the assay was evaluated using a quantitative RNA standard and a pfu-dilution series. To standardize the assay, serial dilutions of transcribed ZIKV RNA were tested by the real time PCR developed (Table 4) .
