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.

Compared to the only available assay based on ZIKV samples obtained during the outbreak in Micronesia, the advantage of our assay is that the primers and probe of our rRT-PCR assay were designed and evaluated using genetic diversity and geographic distribution of ZIKV isolated over 36 years. The developed rRT-PCR assay allowed the detection of 0.5 pfu/ml. This detection limit value is similar to that found by Wu et al., [23] and is therefore sensitive enough to diagnose ZIKV in clinical cases. Indeed, viraemia found in human infection ranges from 102 to 106 pfu/ml [7] , [26] , [15] , [27] .

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.
