French Polynesia is a high epidemic/endemic area for arthropod-borne viruses (arboviruses). We recently reported the silent circulation of Ross River virus and absence active transmission chikungunya (CHIKV) among blood donors sampled before emergence Zika (ZIKV) CHIKV in Polynesia. In this study, prevalence four serotypes dengue (DENV) occurrence other arboviruses were investigated Polynesia.Serum samples from 593 collected between July 2011 October 2013 tested by ELISA presence immunoglobulin G antibodies against each DENV serotypes, ZIKV, Japanese encephalitis (JEV), West Nile (WNV).It was found that 80.3%, 0.8%, 1.3%, 1.5% seropositive at least one serotype, JEV, WNV, respectively.These results corroborate expected conversely suggest no WNV occurred 2011. Information provided study may be useful public health authorities to improve surveillance implement strategies prevent arboviruses.
